【摘要】 锂离子电池正极材料是锂离子电池发展的关键。对锂离子电池正极材料进行包覆是改善其性能的有效方法。锂钴氧和锂锰氧正极材料表面包覆后的循环性能,特别是高温下的循环性能可以得到有效的改善。对于LiFePO4来讲,表面包覆主要是解决这类正极材料导电性问题。文章综述了国内外锂离子电池材料表面包覆的研究现状,提出了作者对将来研究方向的一些看法和建议。更多还原

【Abstract】 To prepare high performance anode materials is a key factor for Li-ion batteries.Surface coating is an effective way to improve the performance of anode materials.The cycling performance of anode materials Li-Co-O and Li-Mn-O composite oxides can be obviously improved by surface coating technique,particularly at elevated temperature.In this paper,current research status of surface coating of anode materials for Li-ion batteries is reviewed,the suggestions and future research targets are put forward.更多还原
