High-temperature lithium-ion battery technology:

The anode material is doped with metal elements by the calcination process, which improves the crystal structure stability of lithium cobalt oxide at high temperatures, reduces the oxidation capacity of the material, and inhibits the reaction between the electrode material and the electrolyte.

The cell of the 18650 li-ion battery has superior anti-swelling and high safety performance, and is especially suitable for high-temperature environments.
