Abstract
Electrochemical behavior of the composite electrodes containing Li2.6Co0.4N and nano-size SiO1.1 has been investigated with the solid poly (ethylene oxide) electrolytes at various temperatures. The composite electrodes have a high first cycle efficiency of ca. 100% and a large reversible capacity of ca. 500 mAh g−1. Result reveals that the operating temperature and the electrode composition dominate the cycling performance. Dispersing a certain amount of sub-micro ceramic BaTiO3 within the electrodes is favorable for improving the morphology stability of the composite electrodes at the elevated temperature. Some factors influencing the electrode properties are presented and discussed in detail.
