Novel High Rate Lithium Intercalation Cathode Materials

Abstract
Mesoporous materials based on an aluminum-phosphorous-oxygen framework containing manganese and vanadium have been prepared with a pore spacing of roughly 4 nm. The mesoporous nature of the matrices was observed to degrade with increasing content of manganese or vanadium. The electrochemical performance of these matrices as lithium intercalation cathode materials was evaluated. Although their specific capacity is less than that of the corresponding metal oxides, these materials showed very good reversibility and rate capacity. © 2001 The Electrochemical Society.
