When considering Solar Lithium Battery Safety, it’s crucial to act fast if a solar lithium battery catches fire. First, move everyone to a safe place far from the fire. Do not use water unless experts say it is okay, as lithium fires require special methods to cool them down. These fires can escalate quickly because heat spreads to other parts of the battery. Over 25,000 fires or overheating cases have occurred in five years involving lithium batteries. Understanding how to stay safe with these batteries is essential for everyone.
What Are The Hazards of Lithium Battery Fires?
Toxic Gas Production
When a lithium battery burns, it releases harmful gases. These gases can hurt your health and are dangerous in closed spaces. Studies show that burning batteries release hydrogen fluoride (HF), ranging from 20 to 200 mg/Wh of energy. HF is very corrosive and can damage your lungs. Another gas, phosphoryl fluoride (POF3), is also released at 15–22 mg/Wh during fires.
Using water mist to fight the fire can make things worse. It may help control flames but increases HF production. This shows why safety steps are so important during these fires. A study called Toxic fluoride gas emissions from lithium-ion battery fires explains how much gas is released. It stresses the need for being prepared and staying safe.
Tip: Always wear safety gear and ensure good airflow when near a burning lithium battery to avoid breathing toxic gases.
High Temperatures
Lithium battery fires create very high heat, which spreads quickly. This heat can damage buildings and cause more fires. The heat comes from a process called thermal runaway. Thermal runaway happens when the battery gets too hot inside and starts burning flammable parts.
In U.S. aviation, there were 274 thermal runaway cases over 23 years. Most happened after 2015 and caused serious harm or even deaths. The heat from these fires can ignite nearby items, making it harder to stop the fire.
Note: Extreme heat can lead to explosions, especially in bigger batteries, making the situation more dangerous.
Strong Currents
Lithium batteries hold a lot of energy, which can release fast during a fire. This sudden energy causes strong currents that may start more fires or create electrical sparks. Reports on energy systems show explosions caused by these sparks, proving the danger.
Strong currents mixed with flammable gases make these fires very risky. For example, the study Experimental Investigation of Explosion Hazard from Lithium-Ion Battery Thermal Runaway found that gas buildup during thermal runaway can cause explosions in large batteries.
To stay safe with Solar Lithium Batteries, learn about these dangers and follow safety rules. Storing, handling, and caring for batteries properly can lower the chances of fires or explosions.
Difficulty in Extinguishing
Solar lithium battery fires are very hard to put out. Their unique chemicals and heat make them tricky to control. Even after being extinguished, these fires can start again. Knowing these challenges helps you stay safe.
One big problem is keeping the battery cool over time. Lithium batteries can overheat inside, causing a chain reaction called thermal runaway. This makes the fire spread fast and hard to stop. Studies show that spraying foam in short bursts helps cool better. Using pressures between 0.4 and 0.6 MPa works best for long cooling. Higher pressures cool faster at first but don’t work as well later.
Here’s a table showing important findings:
Finding | Detail |
|---|---|
Extinguishing Time | CNF can stop flames on a 280 Ah LFP battery in 14 seconds at 0.7 MPa pressure. |
Cooling Efficiency | Pressures of 0.4–0.6 MPa work better for long cooling. Higher pressures cool faster but don’t last as long. |
Challenges | Keeping the battery cool is tough; foam bursts help improve cooling. |
These facts show why special tools and skills are needed for these fires. Always call trained experts and use advanced fire systems to handle them safely.
Risk of Self-ignition or Explosion
Solar lithium batteries can catch fire or explode on their own. Overheating, damage, or factory defects can cause these problems. Knowing these risks helps keep you safe.
Worldwide, many accidents with lithium battery storage systems have happened. Between 2011 and 2021, 32 fires and explosions were reported. Some examples include:
A fire at a test site in Brussels, Belgium, in 2017.
A fire at a cement factory in South Korea in 2018, costing $3 million in damages.
An explosion in Houston, Texas, in 2017, breaking windows 500 feet away.
A fire in Peoria, Arizona, in 2019, injuring eight firefighters.
An explosion in Beijing, China, in 2021, killing three people.
These events show why safety steps are so important. The NFPA 855–2023 rule says large battery stations must have explosion protection. Following these rules and using new technology can lower the risks of solar lithium batteries.
How To Put Out A Solar Lithium Battery Fire?
Cut Off the Power Supply
If a solar lithium battery catches fire, turn off the power first. This stops electricity flow and prevents the fire from getting worse. Lithium batteries hold a lot of energy, and cutting power lowers the chance of sparks or spreading flames.
Find the main switch or circuit breaker linked to the battery. Use tools with insulation to avoid getting shocked. If the fire is too big, focus on staying safe and call experts for help.
Tip: Learn where your battery system’s power switches are located. This helps you act fast in emergencies.
Use Water for Cooling
Water helps cool down solar lithium batteries during a fire. It absorbs heat and slows the spread of flames caused by overheating. Spraying water mist directly on the battery cells keeps the fire from moving to other parts.
Research shows water mist works well to cool lithium batteries. For example, spraying water mist for five minutes can fully stop fires without them restarting. Water cooling systems can also control battery heat during normal use or overheating.
Use water as a mist or spray, not in large amounts. Too much water can cause short circuits or damage nearby electronics. Special water mist systems are best because they cool effectively without using too much water.
Note: Never spray water on batteries still connected to live electricity unless it’s confirmed safe.
Employ Water-based Fire Extinguishers
Water-based fire extinguishers are great for putting out solar lithium battery fires. They cool the batteries and stop flames from restarting by addressing overheating. Unlike dry powders, water-based extinguishers prevent the fire from coming back.
Studies show water-based extinguishers work better than other methods. For instance, water sprays cool batteries the most and stop overheating from spreading. Dry powders only stop flames briefly, and fires can restart quickly.
Some systems mix water mist with gases to improve safety in large areas. These systems cool batteries and remove oxygen to stop the fire. Clean agent systems, which leave no residue, are also good for delicate electronics.
Extinguishing Agent | Cooling Effectiveness | Stops Overheating Spread | Notes |
|---|---|---|---|
Best | Yes | Stops overheating from spreading. | |
ABC Ultrafine Dry Powder | Moderate | No | Overheating spread in three batteries. |
BC Ultrafine Dry Powder | Low | No | Failed to stop overheating spread. |
Novec 1230 | Moderate | Yes | Good for stopping fire and toxic gas. |
Choose water-based extinguishers for the best results with lithium battery fires. Always follow safety rules and ask experts for advice when handling large battery systems.
Cover with Sand or Wet Towels
If other tools aren’t available, use sand or wet towels. Sand blocks oxygen, which slows down the fire’s spread. Wet towels cool the battery and lower the chance of flames restarting. These methods are easy and work well for small fires.
To use sand, grab a bucket or shovel. Cover the burning battery fully with a thick sand layer. This stops oxygen from reaching the fire and smothers the flames. Sand is helpful outdoors or where water and extinguishers aren’t nearby.
Wet towels are another good choice. Soak a towel in water, then squeeze out extra water. Place the towel gently over the battery, covering it completely. The wet towel absorbs heat and cools the battery, stopping it from overheating.
Tip: Wear gloves and stay at a safe distance when handling burning batteries. Safety is the most important step.
These methods are useful in emergencies but not as good as professional tools. For bigger fires, call emergency services right away. Knowing these steps can help you stay prepared and improve Solar Lithium Battery Safety.
