摘要
对锂离子动力电池非石墨化碳负极材料硬碳和软碳的结构和性能进行了比较研究,发现非石墨化碳负极材料其大电流性能尤其突出,甚至可在-20℃低温大电流充电,表现出了优异的倍率和低温性能。同时发现,硬碳放电性能优于软碳,而软碳充电性能则更优。
The structure and properties of non-graphitic carbon anode materials hard carbon and soft carbon for lithium ion power battery were studied.It's found that non-graphitic carbon anode materials show outstanding high current performance,and even charged at-20℃with large current,perform excellent rate capability and low temperature performance.It’s also found that the discharge performance of hard carbon is better than that of soft carbon,while the charge performance of soft carbon is better.
