Title: Silver manganese vanadium oxide electrodes for lithium batteries

Abstract

This invention relates to electrodes for non-aqueous lithium cells and batteries. More specifically, the invention relates to silver manganese vanadium oxide positive electrodes for such cells and batteries. The silver manganese vanadium oxide electrodes may contain substituents or dopants to improve the electrochemical properties of the electrodes, cells and batteries. The silver manganese vanadium oxide electrodes optionally contain silver powder and/or silver foil to assist in current collection at the electrodes and to improve the power capability of the cells or batteries. The invention also includes a method for preparing the electrodes by decomposition of a permanganate salt, such as AgMnO4, KMnO4, NaMnO4 or LiMnO4 in the presence of a compound or compounds containing silver and/or vanadium.
