It’s likely that many of the electronic devices in your home today are powered by lithium-ion batteries. Lithium-ion batteries are found in everything from cell phones and children’s toys to power tools, e-bikes, and even electric cars. These rechargeable batteries are ideal for electronic devices that need to efficiently release large amounts of power in a short period of time, and they are more environmentally friendly and cost-effective than disposable batteries. However, if lithium-ion batteries overheat, become damaged, or are exposed to salt water, they can catch fire and explode.

You may have noticed that there have been many news reports about lithium-ion battery fires in recent years. For example, in 2024, after Hurricanes Helene and Milton, salt water came into contact with lithium-ion batteries in electric vehicles and other battery-powered devices such as golf carts and scooters, causing several house fires. If you’ve flown in recent years, you may have also noticed that carrying a spare lithium-ion battery with you has become a requirement for aviation safety. These incidents have heightened public awareness of lithium-ion batteries, but the actual fire risks are not fully understood by everyone.

Why are lithium-ion batteries so popular?

One significant advantage of lithium-ion batteries is that they allow for more compact devices. Lithium is the lightest metal element, which allows lithium-ion batteries to store more energy in a relatively small space, making for smaller, lighter electronic devices. For portable devices like mobile phones, lightness and compactness are the top consumer demands.

In addition, the rechargeable nature of lithium-ion batteries also makes them more attractive than traditional disposable batteries. Not only can consumers reduce the hassle of frequently purchasing new batteries, but lithium-ion batteries also have no "memory effect." This is different from other types of rechargeable batteries (such as nickel-cadmium batteries), which can cause capacity and voltage to drop if they are recharged without being fully discharged. Lithium-ion batteries avoid this problem, ensuring longer-term efficiency.

Are lithium-ion batteries a fire hazard?

Lithium-ion batteries are generally safe if they are stored, used, and charged properly. To ensure safety, follow these recommendations when using lithium-ion batteries:

• Store batteries in a cool, dry place away from flammable items and avoid moisture. Do not expose batteries to sunlight or extreme cold.

• Follow the battery storage guidelines provided by the device manufacturer.

• Always use the charger that came with the device. Some chargers have a temperature-regulating feature to ensure that the battery doesn't overheat. Using an inappropriate charger can cause the battery to overcharge, which can pose a safety hazard.

• Always unplug the power cord after charging is complete to avoid overcharging.

• Do not charge your device in bed or under a pillow, and ensure that there is enough air circulation around the device to keep it cool.

Also, lithium-ion batteries don't last forever. Typically, they last two to three years, or about 500 charge and discharge cycles. Common signs of battery aging include slower charging, overheating, swelling, or losing power when not in use. If these problems occur, the battery should be replaced as soon as possible, and never replace a lithium-ion battery yourself without the manufacturer's guidance.

What causes lithium-ion battery fires?

The root cause of lithium-ion battery fires is a phenomenon called "thermal runaway." When the battery cannot effectively release the heat it generates, its temperature rises rapidly, causing a fire or explosion. Counterfeit batteries are a greater risk because they are usually of poor quality and prone to this problem.

Here are some factors that can cause lithium-ion battery fires:

• Leaving the battery plugged in after charging is complete

• Physical damage to the battery or its casing

• Using a charging method that is too fast (usually with a non-designated charger)

• Exposing the battery to extreme heat or cold

• Exposing the battery to salt water, such as when stored in a basement or garage that could be flooded

• Using uncertified batteries

As electric scooters, electric bikes, and other mobility devices become more popular, many fires caused by lithium-ion batteries have occurred in these devices. Residents living in multi-unit housing, especially those who need to charge these battery-powered devices at home, are at an increased risk of fire.

As I continue to work with alkaline batteries, I’m increasingly impressed by their performance. Despite their small size, these batteries are packed with power, making them a modern marvel. When paired with cutting-edge LED technology, a couple of AA alkaline cells can provide hours of bright light. Even in more demanding applications, such as two-way radios, alkaline batteries can outlast rechargeable alternatives, providing long-lasting power for communications.

One of the most surprising revelations comes from the fact that twelve D alkaline batteries can power a medical suction device for anywhere from six to nine hours. This impressive power density—storing a significant amount of energy in a small, compact form—is one of the main reasons alkaline batteries can serve such a wide variety of functions.

Long Shelf Life: A Key Advantage

Another remarkable feature of alkaline batteries is their long shelf life. These batteries typically remain viable for up to ten years after manufacture, which is why many people stockpile them for emergency preparedness. If you ever check the expiration date on a pack of alkaline batteries, you’ll notice this impressive shelf life. However, it's important to note that while they may still be good after a decade, their capacity will often decrease. By the tenth year, a battery may retain only around 50% of its original capacity, meaning that while they will still work, they won’t last as long in devices.

If you're saving batteries for a critical use, it’s a good idea to ensure that they aren’t too far past their expiration date. Ideally, you want to have at least seven years before they expire. But don’t let your alkaline batteries go to waste. As they near their expiration, you can cycle them into less critical applications, saving your new batteries for essential uses. This helps ensure that you’re not discarding potentially useful power.

The Availability and Versatility of Alkaline Batteries

Alkaline batteries are also incredibly ubiquitous. As one emergency preparedness expert put it, "You can hardly throw a rock without hitting a place that sells alkaline batteries." This is a massive advantage during emergencies when normal supply chains may be disrupted. In fact, alkaline batteries are among the first supplies to be airlifted into disaster-stricken areas, ensuring that essential equipment remains operational.

Recognizing these advantages, manufacturers of medical devices, like Powered Air Purifying Respirators (PAPR), have started to offer alternatives powered by alkaline batteries. These devices, which protect healthcare workers from contaminants, no longer require external power sources or proprietary rechargeable batteries. Similarly, medical aspirators that run on standard D-cell batteries are now available, providing more flexibility in emergency and remote environments.

The Quality Variance in Alkaline Batteries

That said, not all alkaline batteries are created equal. During testing for a medical aspirator powered by alkaline batteries, we discovered significant differences in performance across brands. A reliable rule of thumb is to always choose well-known, trusted brands for alkaline batteries. Generic or off-brand batteries tend to have lower capacity and shorter run times, which can be critical when the battery life is a key factor in your device's performance.

Conclusion

Alkaline batteries remain a staple in both everyday and emergency use due to their impressive energy density, long shelf life, and broad availability. Whether you're powering simple household devices or critical medical equipment, their reliability makes them an excellent choice. Just remember to check the expiration dates, cycle older batteries into less demanding tasks, and always go for reputable brands for the best results.

Alkaline batteries have a longer service life and higher voltage, and can usually be used for a longer period of time.

The main difference between carbon-zinc batteries and alkaline batteries

• Electrolyte type: Carbon-zinc batteries use zinc chloride as the electrolyte, while alkaline batteries use potassium hydroxide. This difference makes the battery performance and service life of the two batteries different.
• Service life: Carbon-zinc batteries can usually be used for about 18 months, while alkaline batteries can last for about 3 years, suitable for long-term low-power applications.
• Time and stability of power supply: Alkaline batteries provide a longer and stable power supply than carbon-zinc batteries, especially in devices with higher requirements for battery capacity and stability.

Comparison of prices between carbon-zinc batteries and alkaline batteries

Due to their stronger performance and longer service life, alkaline batteries are usually slightly more expensive than carbon-zinc batteries. However, considering the performance advantages in long-term use, alkaline batteries tend to be more cost-effective.

Comparison of Lithium Batteries and Alkaline Batteries

Although alkaline batteries are better than carbon-zinc batteries, the advantages of lithium batteries are more obvious when compared with lithium batteries. Lithium batteries have a higher energy density than alkaline batteries, which makes them superior in size, weight and performance. The voltage of lithium batteries is generally 3.7V, which is much higher than the 1.5V of alkaline batteries. In addition, lithium batteries have a wider operating temperature range and can provide stable power supply under extreme environmental conditions.

In addition, lithium batteries are more environmentally friendly and have a longer life than alkaline batteries, making them a more efficient and environmentally friendly battery choice.

Summary

In general, alkaline batteries have a longer service life and more stable performance than carbon-zinc batteries, and are suitable for devices that require long-term power supply. Although alkaline batteries are slightly more expensive, in many cases, choosing alkaline batteries will be more economical and practical.

If the performance requirements of the battery are higher or it needs to be used in extreme environments, lithium batteries are a better choice. It not only provides higher voltage and longer life, but also has obvious advantages in environmental protection and efficiency. Ultimately, which battery to choose depends on your specific needs and budget.

Whether you're decking the halls or buying gifts for the holidays, your preparations may involve something with a button battery. Button batteries (or disc batteries) are widely used to power a variety of everyday items around the home, such as watches, clocks, small remote controls, electronic candles, hearing aids, toys, keychains, musical greeting cards, children's audiobooks, and light-up or musical holiday decorations. These small, yet useful devices are certainly charming to look at, but they also pose a hazard that should not be ignored.

According to statistics from the Battery Ingestion Hotline, more than 3,500 people of all ages in the United States swallow button batteries each year. Although these batteries are small and usually not easy to notice, once swallowed, they can cause serious health problems, especially in children, where the consequences can be serious and even life-threatening.

Risks of swallowing button batteries

Once a child swallows a button battery, the battery releases electrical current and chemicals in the body, which can cause several serious consequences:

• Burns and corrosion: The alkaline substances in the battery can cause severe burns to the digestive tract, causing damage to the esophagus and stomach, and even possible perforation.

• Poisoning: Heavy metals inside the battery, such as mercury and cadmium, may enter the bloodstream and cause a poisoning reaction.

• Choking: If the battery gets stuck in the airway, it may cause difficulty breathing or choking.

• Organ damage: If the battery stays in the body for too long, it may cause organ damage or serious infection.

According to research, serious consequences can occur quickly within hours if a button battery is swallowed without prompt medical attention. Therefore, once an accidental swallowing occurs, parents need to react quickly and send the child to the doctor in time.

What should I do if my child swallows a button battery?

Since there is no way to know if the battery will penetrate or get stuck, it is important to seek medical help immediately.

• Call the emergency center for emergency medical assistance and try to remember the time when the battery was swallowed.

• Do not let your child eat or drink water to avoid food or liquids aggravating the injury. If your child swallows a button battery, do not let them vomit. This will make the reaction more severe.

• Do not use nose drops or ear drops to move the battery unless instructed by a medical professional.

• If the battery is still in the esophagus, an X-ray may be needed to locate it and dispose of it promptly.

How to prevent button batteries from being swallowed accidentally?

• Keep away from children: First, parents should store items containing button batteries out of reach of children. For example, place remote controls, electric toys, electronic devices, etc. in high places or lock them up.

• Choose products with safe designs: When buying children's toys and electronic devices, give priority to products with safer battery compartment designs. Some products have battery compartments with anti-tampering designs that require tools to open, which can effectively prevent children from contacting batteries.

• Check household items regularly: Parents should regularly check battery-powered devices at home to ensure that the battery cover is completely closed and undamaged. If the battery cover is loose or damaged, it should be repaired immediately.

• Educate children: As children grow up, they can be properly educated on safety to let them understand the dangers of button batteries and avoid putting them in their mouths.

• Dispose of batteries in a timely manner: If there are old button batteries at home, they should be properly discarded to avoid children's contact. For damaged batteries, parents should dispose of them in a timely manner to prevent children from swallowing them by mistake after picking them up.

The voltage drop ‌ is the decrease in voltage caused by the presence of resistance when the current passes through a resistor or conductor in a circuit.

The voltage drop is mainly caused by the following reasons.

1.‌Resistor. ‌When the current passes through the resistor, the resistor consumes part of the electric energy, which is converted into heat energy, resulting in lower voltage.

2.Current. The higher the current, the greater the voltage drop.

3.Wire length. The longer the wire length, the greater the resistance, the greater the voltage drop.

4.Wire cross-sectional area. The larger the cross-sectional area of the wire, the smaller the resistance and the smaller the voltage drop.

5.Wire material. Wires of different materials have different resistivity. The greater the resistivity, the greater the resistance, and the greater the voltage drop.

Voltage Drop will have a variety of effects on the lamp ‌, mainly including the following aspects of the impact.

1.Brightness drop. When the voltage is below the appropriate level, the brightness of the bulb will decrease. This is because the resistance in the bulb causes the voltage to be distributed to various parts, resulting in insufficient voltage, and the bulb cannot emit enough light.

‌2.Shortened life. Low voltage will cause the life of the lamp to be shortened. The lamp needs more current in the case of low voltage to emit enough light, which will accelerate the aging of the resistance, wire, circuit board and other parts of the lamp, thus shortening the service life of the lamp.

3.Flicker and burn. When the voltage is low to a certain degree, the bulb may flicker and even burn. This is because the lamp needs more current to drive in the case of insufficient voltage, and the temperature will rise, which is easy to cause short circuit or overload, resulting in the lamp burned.

The effect of the voltage drop problem on lighting is universal, including on farm lighting. And this impact will cause direct economic losses to farmers. Is there any way to avoid this effect?

The answer is yes. After the unremitting efforts of the company's research and development team, we finally developed a Smart Poultry Lighting Control System that can not be affected by the voltage drop. The control system is equipped with self-developed drive power supply and control system. The problem caused by voltage drop to lamps has been completely solved. This control box can not only adjust the brightness and timing of the light, but also realize the sub-area control of the light. The farmers who use Intelligent Poultry Lighting Control System are extremely satisfied with the convenience it brings to the farm.

Laying hens are chickens raised specifically to lay eggs for the supply of eggs. The main task of raising laying hens is to improve egg quality and maintain or increase egg production. Laying hens breeds should be selected robust, disease resistance, foraging ability, good egg quality, high egg production rate, and coarse feeding, adapt to the local environment of the local chicken.

The laying rate of hens is very important to farmers. However, sometimes the egg production rate will decrease for some reasons, resulting in economic losses for farmers. So, what causes the decrease in laying rate of hens?

There are many reasons for the decrease in laying rate of laying hens, and the following are some of the main factors.

Environmental Factor

1. Temperature change. Too high or too low temperature can affect the laying rate of hens. For example, high temperature in summer will lead to reduced feed intake and insufficient nutrient intake of laying hens, which will affect egg production. Cold winter may cause cold stress and physiological disorders.

2. Humid environment. Excessive humidity not only affects the normal metabolism of laying hens, but also may breed harmful microorganisms and cause diseases.

3. Poor ventilation. Poor ventilation facilities or insufficient ventilation will lead to the accumulation of harmful gases (such as ammonia, carbon dioxide, etc.) in the house, affecting the health of laying hens and reducing the laying rate.

Nutritional Factor

1. Feed quality. Poor feed quality, moldy deterioration or contamination will reduce the palatability of feed, reduce the feed intake of laying hens, and lead to a decrease in laying rate.

2. Nutrient deficiency. Insufficient protein, vitamins, trace elements and other nutrients in the feed will affect the normal physiological function of laying hens, and then affect the laying rate. For example, the imbalance between calcium and phosphorus can affect the formation of eggshells.

3. Feed mutation. Sudden change of feed will lead to digestive dysfunction of laying hens, resulting in indigestion, which will affect the laying rate.

Disease Factor

1. Infectious diseases. Chickens infected with infectious diseases such as avian influenza, Newcastle disease, infectious bronchitis, etc., can lead to a sudden decline in egg production. These diseases not only affect the egg production rate of laying hens, but also can cause a large number of chicken deaths.

2. Bacterial diseases: Bacterial diseases such as colibacillosis and salmonellosis can also affect the egg production rate of laying hens.

3. Parasitic diseases: Parasitic diseases such as coccidiosis and filariasis can also have a negative impact on the egg production rate of laying hens.

Management Factor

1. Poor feeding management. Feeding is not fixed time and quantity, insufficient drinking water, equipment damage and other feeding management problems will lead to a decrease in laying rate.

2. Stress factors. Stress factors such as abnormal noise, the presence of strangers, vaccination or deworming treatment can also reduce the laying rate of laying hens.

3. Unreasonable light. Insufficient light time or insufficient light intensity will affect the physiological function of laying hens, and then affect the laying rate. 

Now, let's increase egg production in a very simple way. By using our latest research and development product High-tech Intelligent Poultry Lighting Control Box 6020 connected to the Safe LED Poultry Light Bulbs, the farming farmer can adjust the lighting time and brightness to improve lighting condition, then improve the laying rate of laying hens.
