Abstract
The invention provides a lithium battery, including: a cathode plate and an anode plate; a separator disposed between the cathode plate and the anode plate to define a reservoir region; and an electrolyte filled in the reservoir region. A thermal protective film is provided to cover a material of the cathode plate or the anode plate. When a battery temperature rises over an onset temperature of the thermal protective film, it undergoes a crosslinking reaction to inhibit thermal runaway. A method for fabricating the lithium ion battery is also provided.
