锂离子电池正极材料研究现状

综述了锂离子电池正极材料的研究现状,大部分集中在过渡金属氧化物上。不仅包括目前研究较多的层状化合物LiCoO2、LiNiO2和尖晶石型化合物LiMn2O4类正极材料,而且也包括了现在不成熟但有着优异性能和广阔应用前景的锂钴镍复合氧化物、改性的尖晶石、黄铁矿、嵌锂氧化钒、硫以及有机硫等正极材料,并对它们的结构、电化学性能及制备方法之间的关系及近期研究现状进行了阐述。

Recent developments on Li-ion batteries positive materials

The recent development of Li-ion battery positive materials was reviewed. Much attention was paid to the transitional metal oxides.The layered LiCoO_2,LiNiO_2 and spinel LiMn_2O_4 were briefly described.Some positive materials,such as lithium cobalt-nickel oxides, modification spinel, pyrite, intercalation lithium vanadium oxides and organo-sulfide were not mature,but had excellent properties and good applied prospect.The structure and electrochemical properties of these positive materials, the investigative actuality and preparation methods were specified.
