锂离子电池超高容量负极材料的研究进展

Development of Super-high Capacity Negative Electrode Materials for Lithium Ion Batteries

对最近几年锂离子电池用负极材料,特别是首次最大充放电容量超过500 mAh/g的负极材料进行了综述。分类详述了高容量负极材料的研究现状,其中包括碳负极材料(硬碳、碳纳米管、碳的掺杂)和非碳负极材料(锡基负极材料、过渡金属氮化物、新型合金),并对其各自的特点进行了分析,认为超大比容量的锂离子电池用负极材料是未来发展的重要方向。

Negative electrode materials for lithium ion batteries, especially those with maximum first-time charge-discharge capacity above 500 mAh/g were reviewed. The research status and characteristics of the high capacity negative electrode materials were discussed in detail, including carbon negative materials such as disordered carbon, carbon nanotubes and doped carbon as well as non-carbon negative materials such as tin-based negative materials, transitional metal nitride and typical alloys. The developing direction of lithium ion batteries is considered to be on super-high capacity batteries in the future.
