Abstract
A Li-ion battery is disclosed, the Li-ion battery including an anode, a cathode, a lithium donor formed from a Li-containing material, and an electrolyte in communication with the anode, the cathode, and the lithium donor. The lithium donor may be incorporated into the anode, incorporated into the cathode, a layer formed on either an anode side or a cathode side of a separator of the battery. The lithium donor is formed from Li-containing material insensitive to oxygen and aqueous moisture.
