Abstract
Disclosed is a lithium battery including a silicon negative electrode, a lithium mixed metal oxide positive electrode, a separator disposed between the negative and positive electrodes to define a reservoir region, an electrolytic solution filled in the reservoir region, and a sealant structure wrapped around the silicon negative electrode, the lithium mixed metal oxide positive electrode, the separator, and the electrolytic solution. The electrolytic solution includes an organic solvent, a lithium salt, and an additive. The additive includes a maleimide compound and vinylene carbonate. The silicon negative electrode of the lithium battery employing the described electrolytic solution has higher cycle efficiency and longer operating lifespan.
