本文讨论了硬碳负极材料不同比例混合于人造石墨的锂离子电池的性能。实验结果表明:随着在人造石墨中硬碳的比例增加,电池的首次放电效率和放电容量随之降低,电池的倍率充放电性能、低温充放电性能、常温循环和高温循环性能也随之变差。对比100%人造石墨负极电池,当掺杂量达到10%-30%时,电池的性能有所提升;当掺杂量超过30%时,电池性能变差,其中当掺杂量为10%时性能最佳。
Abstract：The paper discusses the performance of lithium ion batteries with hard carbon anode materials mixed with artificial graphite in different proportions.The experimental results show that:with the increasing of the proportion of hard carbon in the artificial graphite,the first discharge efficiency and discharge capacity of the battery decrease,and the multiple charge and discharge performance,low temperature charge and discharge performance,cycle performance of the battery at room temperature and high temperature also become worse.Compared with 100%artificial graphite anode battery,when the doping amount reaches 10%-30%,the performance of the battery is improved.When the doping amount exceeds 30%,the performance of the battery becomes worse,and the best performance is when the doping amount is 10%.
