Lithium Potassium Manganese Mixed Metal Oxide Material for Rechargeable Electrochemical Cells

摘要

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 mAhrs/g of active cathode material.
