All batteries cannot be said to be absolutely safe, but lithium batteries are indeed a relatively safe battery. First of all, lithium batteries have a very good resistance to thermal imbalance, which makes it can be very good to deal with extreme environments like high temperature.
Secondly, the internal chemical properties of lithium batteries are more stable, and lithium batteries have a lot of internal diaphragms and pressure release valves, lithium battery electrode materials compared to other materials will not be rapidly degraded in the overcharging and overdischarging, which makes lithium batteries to withstand overcharging, overdischarging and mechanical damage can be reduced to the extent of the damage, the structural design of these lithium batteries have greatly enhanced the safety of the battery. This shows that lithium batteries are indeed safer batteries.
Under normal circumstances, lithium batteries do not work when the internal chemical reaction is very stable, so it is safer to store lithium batteries at home, but you need to pay attention to the environment around the lithium battery, the battery board should be stored in a dry, cool and ventilated environment, take the humid environment, the battery is in the environment for a long time in the damp, which will greatly reduce the battery performance and service life.
Secondly, you can not cover the metal objects on the surface of the lithium battery, which will lead to the positive and negative poles of the lithium battery are connected, resulting in a short circuit of the battery, which is very serious, not only will make the battery scrapped, but also may cause a fire.
There are many reasons why lithium batteries catch fire, generally can be divided into three categories. That is, improper use, internal defects and mechanical damage to the battery.
Your improper use, such as overcharging, use in high temperature environments can lead to lithium battery fire, take overcharging this case, lithium battery overcharging will lead to an imbalance in the internal chemical reaction of the battery, generating a large amount of heat, the heat continues to accumulate will cause a fire.
Battery internal defects, such as uneven battery materials and missing diaphragm materials, such batteries in the use process compared to normal lithium batteries are more prone to short-circuit conditions, short-circuit will make the internal heat of the battery increases rapidly, and ultimately cause the battery fire this situation.
Battery suffered serious mechanical damage caused by the principle of fire with the battery internal defects are similar, because the battery suffered serious mechanical damage will make the structural integrity of the battery has been damaged, resulting in the use of the battery in the occurrence of short-circuit, which triggered the battery fire.
If your lithium battery is charging process, then you should first cut off the power to prevent further expansion of the fire, after that you can choose to use a dry powder fire extinguisher or carbon dioxide fire extinguisher to extinguish the lithium battery fire, can not use water, because the water will react with the chemicals in the lithium battery, resulting in the battery explosion and the release of toxic gases.
Of course, you should wear protective clothing and goggles before using the fire extinguisher, as much as possible to wrap the exposed skin, and keep a safe distance from the source of the fire, in order to prevent lithium batteries from exploding when the internal chemical substances splashed on your skin.
If the number of lithium batteries is high and a large fire is started, you should leave the fire scene immediately to ensure your life safety and call the fire department immediately, they will handle the fire properly.
First of all, those low-quality lithium batteries are extremely dangerous. These lithium batteries flow to the market through informal channels, usually without strict quality control and without product qualification certificates, so the safety risk of these products is high, and you should pay attention to screening when you buy them.
Secondly, if your lithium battery because of improper use or mechanical damage caused by bulging, electrolyte leakage and other abnormalities, the internal chemical reaction of the lithium battery has been seriously damaged, this type of lithium battery is very dangerous, in the use of the process at any time there may be a fire phenomenon, you need to replace and dispose of this type of battery in a timely manner.
