For now. After long-term development, lithium-ion batteries have been able to guarantee safe application in normal environments, but thermal runaway in overheated or impacted environments cannot be ruled out. Because lithium-ion batteries are mainly composed of positive electrodes, negative electrodes, electrolytes, and diaphragms, their performance is relatively fragile. If they are overcharged or over-discharged for a long time, copper dendrites will form inside, and copper dendrites will easily cause short circuits and cause fires if they pierce the diaphragm. .
This is why two-wheeled vehicles and tricycles are prone to fire. As for how to avoid such accidents, there are two main ideas.
The first is to do a good job in protection, such as: purchase new energy products with national safety certification, do a good job in the inspection and maintenance of electric vehicles on a regular basis; standardize safety behaviors, do not charge with flying wires, and do not overcharge or overdischarge for a long time.
The second is to do a good job in early warning and treatment, such as: installing an automatic spray fire extinguishing device in the battery compartment to detect fires in advance, automatically spray and deal with "initial small fires". Raise safety awareness, and prohibit the use of electric vehicles when they realize that there are abnormal phenomena in electric vehicles. Learn the correct way to deal with fire, and deal with it in time when a fire is discovered, so as to avoid huge losses to people and property caused by fire.
