what is ion for li?
<answer> In a lithium-ion battery, the lithium ion is the cation that travels from anode to cathode. <context> Lithium cobalt oxide consists of layers of lithium (show here as purple spheres) that lie between slabs formed by cobalt and oxygen atoms (shown here as connected red and blue spheres). 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 LiPF6, LiBF4, or LiClO4, in an organic solvent, such as ether.
