作为锂二次电池负极的炭材料

CARBON MATERIATS AS NEGATIVE ELECTRODES FOR LITHIUM SECONDARY BATTERIES

炭材料替代金属锂作为锂二次电池的负极,由于它的高性能、高循环效率及安全可预测性,已越来越引起人们的广泛注意,成为电池领域的热点。本文综述了石墨层间化合物及炭材料负极的研究运态,介绍了金属锂作为负极导致循环效率低、不安全的原因及所采取的改善办法,并分析了炭替代金属锂的可能性。

Much attention had been devoted to carbon materials as negative electrodes for lithium rechargeable batteries instead of metal lithium because of their high pefo-rmance,cycle efficiency and predictable safety .This paper reviewed the trend of study on GlCs and carbon materials as anode of Li secondary cells.The reason of poor eyed efficiency and unsafely for Li secondary cells of metal Li as negative electrode and improvement methods were discussed,and the possibility of carbon wh ich substituted for metal Li were also displayed.
