摘要:

负极材料是锂离子电池的重要组成部分, 目前商用锂离子电池的负极材料石墨的理论比容量仅为372 mAh/g, 严重制约了锂离子电池的进一步发展。在众多的锂离子电池负极材料新体系中, 金属氧化物具有理论比容量高、价格低廉、环境相容性好等优点, 受到广泛关注, 但是其存在导电性差、充放电体积变化大等缺点。研究发现, 纳米化可以在保持金属氧化物优点的同时克服其缺点, 因此成为金属氧化物基负极材料的研究热点。本文对近期纳米金属氧化物基锂离子电池负极材料研究的主要成果进行综述, 着重关注几种具有代表性的金属氧化物及其复合物的纳米结构设计与性能优化, 并为后续相关研究提出建议。

Abstract:

Anode material is an important component for Li-ion battery. The current anode materials are mainly based on graphite, which possesses low theoretical specific capacity of 372 mAh/g, and thus hinder the further development of Li-ion battery. Among the newly developed anode materials, metal oxides have recently attracted intense attention due to their high theoretical specific capacity, low cost and environmental friendliness. However, metal oxides own poor electrical conductivity and large volume changes during cycling. Nanosizing can overcome these disadvantages while maintaining the advantages for metal oxide based anode materials, and thus becomes a research hot spot. Herein, we review the recent research advances of the nanostructured metal oxides as anode materials, mainly focusing on the microstructure design and performance optimization of representative metal oxides and their composites. In addition, some suggestions are presented for further explorations in relative fields.

Key words: metal oxides, nanosizing, Li-ion batteries, anode materials, review
