Chemical composition of lithium battery: The positive electrode includes a current collector composed of lithium cobaltate (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and aluminum foil. The negative electrode is composed of a current collector composed of a graphitized carbon material and a copper foil.
The battery is filled with an organic electrolyte solution. Safety valves and PTC components (partially cylindrical) are also included to protect the battery from damage during abnormal conditions and output short circuits.
Lithium metal battery:
A lithium metal battery is generally a battery using manganese dioxide as a positive electrode material, metallic lithium or an alloy metal thereof as a negative electrode material, and a nonaqueous electrolyte solution.
Lithium Ion Battery:
A lithium ion battery is generally a battery using a lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, and a nonaqueous electrolyte.
