In recent years, due to the high energy density and long lifespan of lithium batteries, more and more lithium batteries have replaced lead-acid batteries, and at the same time, the dangers of lithium batteries are also getting more and more attention. The following content will tell you in detail the dangers of lithium batteries.
1.The safety hazards of lithium batteries
(1) Lithium batteries contain a variety of harmful chemicals, water will release some harmful substances, if not handled properly, the human body and the environment will cause harm.
(2) If there is some kind of defect in manufacturing, then it is likely to affect your safety in the future;
(3) Since the electrolyte inside the lithium battery is volatile and flammable, it is likely to cause a fire if used improperly;
(4) If the electrolyte inside the battery leaks, it is very likely to cause poisoning.
2. The causes of fire caused by lithium batteries
(1) Electrical overload: the use of unqualified chargers or overcharging of lithium batteries when charging may cause lithium battery fire, in addition, if the circuit is short-circuited may also cause lithium battery fire;
(2) Equipment damage: when the lithium battery is squeezed, dropped and other circumstances lead to deformation, may cause the battery internal short circuit or fire and other situations occur;
(3) Thermal overload: If the lithium battery is exposed to a heat source that causes the battery to overheat, it may cause the chemical reaction inside the battery to accelerate, thus generating more heat, forming a positive feedback regulation, thus causing the lithium battery to catch fire;
(4) Environmental issues: frequent exposure to humid environments may damage the battery or certain components, a little carelessness in the work of the battery may explode or generate a fire.
3. The consequences of lithium battery fire
If a lithium battery malfunctions and causes a fire, the consequences are very serious. Because of the huge heat generated by the fire of lithium battery, it will be difficult to extinguish it without enough water. Moreover, carbon dioxide fire extinguishers cannot be used on fires caused by lithium batteries, otherwise the fire may be aggravated or cause an explosion.
In the lithium battery fire will also release toxic, flammable and explosive gases, which may cause the battery to explode.
4. How to improve the safety of lithium batteries
(1) Correct storage: store the battery away from metal objects, but also to ensure that the environment is dry and away from heat sources;
(2) Light handling: when handling the battery, pay attention not to let the battery by extrusion, puncture, fall, etc., to avoid causing the battery failure;
(3) Proper charging: use qualified chargers to avoid overcharging caused by overheating of the battery, but also to avoid letting the battery in the overheating or overcooling environment charging.
(4) Regular inspection and maintenance: Regular inspection and maintenance of the battery to prevent the battery from leakage, shell expansion and other situations;
(5) Safe disposal of used batteries: Don’t throw the batteries in the garbage can or on the lawn, but put them in the designated recycling points to prevent harm to the environment.
Conclusion:
Although there are many dangerous factors in lithium batteries, but its performance, the scope of application than other batteries are better, as long as we do a good job of protective measures, regular maintenance of lithium batteries, there will not be too much risk.
