| 摘 要： | 利用共沉淀辅以高温烧结法制备了椭球形三元高镍LiNi_(0.8)Co_(0.1)Mn_(0.1)O_2(LNCM811)正极材料,并用XRD、SEM和TEM对其结构和形貌进行表征。利用CV和恒流充放电测试LNCM811在添加质量含量分别为2%(w/w)DTD(硫酸乙烯酯)、1%(w/w)MMDS(甲烷二磺酸亚甲酯)及其复合添加剂2%DTD+1%MMDS的电解液中的电化学性能,并利用EIS测试其充放电过程中的动力学特性。结果发现相较于1%MMDS,2%DTD能较为显著提高LNCM811在常温的首周放电容量和首周库伦效率;1%MMDS和2%DTD均能提高电极材料的长循环寿命,室温25℃条件下2%DTD比1%MMDS效果更显著,而高温60℃下1%MMDS比2%DTD更为明显;LNCM811正极无论在室温下还是高温下在复合添加剂的电解液中均具有最好循环性能。EIS测试表明2%DTD+1%MMDS复合添加剂能显著降低LNCM811动力学阻抗。
