In a lithium-ion battery, the lithium ion is the cation that travels from anode to cathode. Lithium (Li) is easily ionized to form Li + plus one electron. The electrolyte is typically a combination of lithium salts, such as LiPF 6 , LiBF 4 , or LiClO 4 , in an organic solvent, such as ether.
Lithium-ion (Li-Ion) batteries are rechargeable batteries that are found in electronic devices such as laptops, cell phones, cameras, power tools, and certain specialty devices. These batteries are comprised of nickel, cobalt, copper, manganese, electrolyte, and certain forms of plastic casing.
