Abstract:

A family of potassium-doped manganese oxide materials were synthesized with the stoichiometric formula Li0.9-xKxMn2O4, where X 0.0 to 0.25, and evaluated for their viability as a cathode material for a rechargeable lithium battery. A performance maximum was found at X 0.1 where the initial specific capacity for the lithium - potassium doped manganese dioxide electrochemical couple was 130 mAhrsg of active cathode material.
