摘 要：<正>Layered lithium cobalt oxide （Li CoO2） with a theoretical capacity of 274 m Ah·g-1has become a dominant cathode material for lithium-ion batteries of "3C"market （cellular phones,portable computers,camcorders）[1-2]. Nevertheless,the actually attained capacity is merely about 140 m Ah·g-1with a charge cut-off voltage of about 4.2 V （vs Li+/Li）[3]. When cycled to higher cut-off
