In a preferred battery, a negative electrode contains metallic lithium, a positive electrode contains transition metal chalcogen compound having a reversible lithium insertion ability, a solid electrolyte is disposed between the electrodes, and a protective layer is disposed between the solid electrolyte and the negative electrode. The protective layer contains polyvinyl pyridine (PVP) or derivatives thereof and iodine complexed with the PVP or derivatives thereof for reducing passivation of the lithium-containing negative electrode. Preferably the polyvinyl pyridine is poly-2-vinylpyridine or poly-2-vinylquinoline. |
