Lithium is the same element in both cases, but it is involved in different chemical compounds.
In a lithium battery the lithium is part of lithium cobalt oxide, one lithium atom, one cobalt, and two oxygen. In the medication it is lithium carbonate, which is two lithium atoms, one carbon, and three oxygen. Atoms behave very differently when in different chemical compounds so while the atom is the same they are very different things.
As for why precisely lithium works to treat some kinds of mental disorders… we don’t really know why it works, but it does seem to be effective.
