锰酸锂电池掺杂钴镍对电化学性能影响研究
Effects of cobalt and nickel doping on electrochemical performance of LiMn2O4 batteries
摘要
Abstract
Lithium battery cathode materials were doped with cobalt and nickel through the sintering process,and also the pure phase lithium batteries were prepared.The composition,micro morphology,structure and charge discharge characteristics of the products were characterized by X ray diffraction,plasma emission spectrometer,electrochemical performance test system and electron scanning electron microscope.The study results show that lithium manganese battery doped with cobalt and nickel has high crystallinity,uniform particle and no obvious impurity phase.The initial discharge specific capacities of lithium battery doped with cobalt and nickel are 118.5,108.2 mAh/g capacity,respectively.After 50 cycles,the discharge specific capacity is 110.8,101.9 mAh/g,and the capacity retention is 93.5％ and 94.2％,respectively.关键词
