Why Lithium-Ion Batteries Catch Fire

Common Risks

You use current li-ion batteries every day in phones, laptops, and electric vehicles. While these batteries power your devices, they also come with certain risks. Even though incidents are rare, you should know that they are becoming more frequent and can lead to serious consequences. If a lithium-ion battery gets damaged or used incorrectly, it can overheat or even explode. This can cause a catastrophic fire that is hard to put out. Such fires may result in property damage, burns, or exposure to harmful chemicals and smoke.

Some of the most common risks you face with current li-ion batteries include:

• Fire hazards: Batteries can catch fire or explode if punctured, short-circuited, overcharged, or exposed to high temperatures.
• Chemical leaks: Damaged batteries may leak corrosive substances, causing chemical burns and device damage.
• Toxic inhalation: Burning batteries release toxic fumes that can harm your lungs and health.

You also need to watch out for improper usage, incorrect charging, and unsafe disposal. These actions can increase the risk of fire or explosion incidents.

Even though electric vehicles have a much lower fire rate than gasoline cars, the combustibility of lithium-ion batteries still makes safety a top concern.

Overheating and Physical Damage

Overheating is one of the main reasons why a lithium-ion battery can fail. When a battery gets too hot, it can enter a state called thermal runaway. This process can lead to a fire or even an explosion. Fires from lithium-ion batteries burn quickly and with intense heat, making them very dangerous and hard to control.

Physical damage is another major safety hazard. If you drop, puncture, or crush a battery, you can cause cracks or short circuits inside. These problems can trigger thermal runaway and increase the risk of fire. Impacts or punctures may break the battery’s internal parts, leading to dangerous failures.

Tip: Always handle your devices with care and avoid exposing batteries to extreme heat or physical shocks. Proper use and storage can help prevent catastrophic fire events.

Safety Innovations

Advanced Electrolytes

You can see major progress in battery safety through the development of advanced electrolytes. These new materials help prevent fires and improve the overall safety and performance of lithium-ion batteries. Scientists have designed electrolytes that combine the best features of both liquids and solids. This approach gives you batteries that work well in a wide range of temperatures and resist damage.

Here is a table that shows some of the most promising advanced electrolytes:

You also find new types of electrolytes like 3D-SLISE. This material uses amorphous lithium tetraborate, lithium salt, carboxymethyl cellulose, and water. It allows lithium ions to move in all directions, which boosts conductivity and battery life. The 3D-SLISE electrolyte achieves a battery voltage of 2.35 V and can handle over 400 charge and discharge cycles at high rates. Its water-based composition makes recycling easier and safer for the environment.

• 3D-SLISE lets lithium ions move freely, which improves conductivity.
• You get more than 400 cycles at fast charging rates.
• Water-based design supports easier recycling.

Advanced electrolytes also use thermo-responsive features. These features help the battery respond to temperature changes. If the battery gets too hot, the electrolyte or separator can react and stop the battery from overheating. This action lowers the risk of thermal runaway, which is the main cause of battery fires.

Protective Materials

You benefit from new protective materials that make batteries safer and more reliable. Researchers have created composite materials that resist heat and fire. These materials help stop fires before they start and protect the battery during accidents.

Some of the most effective protective materials include:

• Flexible and heat-resistant polyphenylene sulfide ultrafine fiber hybrid separators. These separators keep the battery stable, even if it gets damaged.
• The FR.10 composite, made from carbon fibers and silicone resins. This material is lightweight and thin, but it adds strong fire resistance.
• Polybenzimidazole-based composites. These materials improve fire safety and help batteries work at high temperatures.

You also see batteries with built-in fire suppressants. Laboratory tests show that water mist systems work much better than dry chemical or Class D powder systems. Water mist can put out lithium-ion battery fires and prevent them from starting again. The longer release time of water mist, about 5 minutes, gives you more protection compared to the short bursts from other systems.

Laboratory tests show:
"Water mist is significantly more effective than dry chemical and Class D powder in extinguishing lithium-ion battery fires and preventing reignition. Water mist systems can extinguish fires without reignition due to their longer release time of 5 minutes, compared to the 35-50 seconds for dry chemical and Class D powder systems, which only provide temporary extinguishment."

Companies like KULR Technology, working with NASA, have developed special tools to measure and control heat during battery failures. The fractional thermal runaway calorimeter (FTRC) helps engineers understand how much heat a battery releases during a failure. This knowledge leads to safer battery designs and better ways to stop fires before they spread.

You can trust that these innovations in electrolytes and protective materials are making a real difference. The development of these new technologies means you get batteries that are safer, last longer, and perform better in your devices. As more companies use these solutions, you will see fewer battery fires and more reliable products in your daily life.
