Abstract

A composite, Li V3 O8 -polypyrrole (PPy), was synthesized by a low-temperature solution route followed by an in situ polymerization method. The as-prepared powders consisted of nanosized PPy distributed homogeneously within the layered lithium trivanadate. The electrochemical properties of Li V3 O8 -PPy composite were systematically investigated and compared with bare lithium trivanadate. It was found that the electrochemical performance of the Li V3 O8 -PPy composite was significantly enhanced, with a specific capacity of ∼183 mAh g-1 retained after 100 cycles. This suggests that nanostructured PPy could work well as a polymer-conducting matrix and also as a binding material to improve the overall electrochemical properties of the Li V3 O8 when used as a cathode material in lithium-ion batteries. © 2007 The Electrochemical Society.
