Sure. Lithium carbonate is a chemical that's used to make some of the positive electromaterials for lithium-ion batteries. It's a combination of lithium, carbon and oxygen. It has some very nice properties in that it's quite stable in the air and relatively moisture-insensitive.
Lithium hydroxide is a combination of lithium, oxygen and hydrogen. It's usually sold in the hydrated form of lithium hydroxide monohydrate. It's also used in the production of usually positive electromaterials that have a high nickel content.
These two materials are the most common materials used in the synthesis of the positive electromaterials for the lithium-ion battery.
