摘　　要：目前,锂离子动力电池低温充电性能较差的问题,一直制约着动力电池的发展。采用无定型碳包敷负极复合型材料并结合功能电解液的使用,可有效地改善锂离子电池在低温-20℃下的充放电能力,通过与常温充放电性能对比,表明这种无定型碳包敷负极复合材料可以实现动力锂离子在低温下充放电。The problem of the unsatisfied low temperature charge performance of lithium-ion power cell restricts the development of power battery. In this study, we applied amorphous carbon to coat cathode composite material companied with functional electrolyte. The results showed that such design can effectively improve the charge performance of lithium-ion power cell at 20 oC, compared with that at room temperature. It is indicated that this amorphous carbon to coat cathode composite material can successfully lead to the charge behavior of lithium-ion power cell at lower temperature.
