Electrochemically Active Interlayers for Lithium Ion Batteries

Abstract

This disclosure is geared toward a lithium ion battery cell system. The system includes an anode current collector in contact with an anode, a separator in contact with the anode, an electrolyte, a cathode, an additive layer situated between the separator and the cathode, and a cathode current collector. The additive layer may include at least one of a transition metal sulfide, a transition metal oxide, and a transition metal phosphate.

Dependencies are inferred from the claim text.
