Title: Cathode additives for lithium-ion batteries

Abstract

In some implementations, a cathode is formed by (1) providing a cathode additive including (a) a matrix including a lithium compound, and (b) metal nanostructures embedded in the matrix; and (2) combining the cathode additive with a cathode active material to form a mixture. In other implementations, a cathode is formed by (1) providing a cathode additive including a compound of lithium and at least one non-metal or metalloid; and (2) combining the cathode additive with a cathode active material to form a mixture.
