Abstract

Abstract : The poor electronic conductivity restricts the wide applications of Li4 Ti5 O12 as anode materials in Li‐ion batteries. We report a facile approach to fabricate nitrogen‐doped carbon‐coated Li4 Ti5 O12 through carbonizing pyrrole and pyridine at different temperatures. Comparative experiments demonstrated that the carbon content plays a key role in governing the cycling performance and rate capability of Li4 Ti5 O12 . The composites with higher carbon content exhibited superior cycling performance, and the composite prepared at 600 °C using pyridine as the carbon source gave the best cycling and rate performance. Abstract : Nitrogen‐doped carbon‐coated Li4 Ti5 O12 was achieved by a simple method. Pyrrole and pyridine were used as carbon sources. The carbon content plays a key role in electrochemical performance.
