Abstract

The present invention discloses three classes of electrolyte additives for use in secondary lithium batteries. The secondary lithium battery may comprise a positive electrode, a negative electrode, an electrolyte, a porous separator between the positive and negative electrode, and an electrolyte additive. The electrolyte additive in the secondary lithium batteries may include non-lithium salts, inorganic fillers, and polymer additives. The use of electrolyte additives and combinations thereof improves the cell performance of secondary lithium batteries.
