摘要
综述了常见的金属氧化物、磷酸盐、碳和聚合物表面包覆改性锂离子电池正极材料LiCoO2、LiMn2O4和LiFePO4等的研究现状。在已研究过的表面包覆物中,导电聚合物因不但具有嵌锂功能,还能增强材料表面的导电性而备受关注。
Research status quo of metal oxide,phosphate,carbon and polymer surface coating of cathode materials such as LiCoO2,LiMn2O4 and LiFePO4 was reviewed.Among the above surface coating materials,electrically conductive polymer was aroused much concern because it not only had lithium intercalation function,but also could enhance the surface conductivity of the materials.
