60℃.
This is because the organic components of the lithium battery electrolyte will decompose in high temperature environments, producing flammable and explosive gases, which can trigger runaway reactions thermal under high temperatures and pressures. Additionally, when lithium batteries are used normally, the internal temperature also increases as energy is consumed, increasing the risk of explosion. Lithium battery is a new type of efficient, energy-saving and environmentally friendly battery. It is widely used in smartphones, tablets, laptops, electric vehicles and other fields. However, there are certain safety risks when using and storing lithium batteries, including explosion accidents in high temperature environments.
