【摘要】 对锂离子电池碳负极材料表面进行镀膜处理,并对处理前后的电极进行电化学容量测试和扫描电镜形貌分析。结果表明,镀膜处理后的电极的充放电容量提高了10％～15％,而充放电效率和电压平台基本没有改变。结合电镜结果对这一现象进行了分析和讨论。更多还原

【Abstract】 The effect of plating on the anodic characteristics of carbon was investigated. This treatment led to a large increase in charge and discharge capacity which was attributed to the formation of a new membrane on the surface of carbon. But the membrane did not affect the voltage plateaus of the studied materials. SEMs of these materials were also discussed to explain the discrepancy of their capabilities.更多还原
