According to the news of Battery.com.cn, there have been many reports about the explosion of mobile phone batteries , which has also aroused public concern and anxiety. So, why is the cell phone battery exploding? How likely is it to appear? How can we avoid this? Compared with other battery technologies, lithium-ion batteries are lighter, cheaper, and have higher energy density. They have become the main form of rechargeable batteries today, and lithium-ion batteries are used in everything from mobile phones to laptops. But this battery has a problem, and in some extreme cases, it may explode. Lithium-ion batteries have an explosive tendency, and they are all caused by a process called "thermal runaway." Essentially, "thermal runaway" is a process of positive energy feedback loops: elevated temperatures cause the system to heat up, and the system heats up to raise the temperature, which in turn makes the system hotter. Lithium-ion batteries have many reasons for thermal runaway. For example, when the two ends of a lithium battery are connected by conductors, the tearing of the membrane of the negative electrode and the positive electrode of the isolated lithium ion battery causes a short circuit, and the short circuit often causes thermal collapse. Lithium-ion batteries also cause fires: ambient temperatures in excess of 60 ° C, frequent overcharging, physical damage, etc. Regardless of the cause, it is the cobalt oxide chemistry in the battery that goes through this reaction. If you heat this chemical and reach a certain temperature, it begins to self-heat and then develops into a fire and an explosion.
