复合导电剂对富锂固溶体材料性能的影响
Effect of composite conductive on performance of Li-rich solid solution materials
摘要
Abstract
Effects of different ratio of vapor growth carbon fiber(VGCF) and Super-P on the performance of Li-rich solid solution material were investigated,which were Li-rich solid solution material as active materials,Super-P as conductive agents,VGCF as an another conductive material.A 3 dimensions conductive network was formed on the surface of the second particles of active materials when adding VGCF into the conductive.With the increase of VGCF's content,the rate capabilities were changed.The specific capacity was increased firstly and then decreased,when the content of VGCF was increased.The discharge was 183.6 mAh/g at 3 C,when the content of VGCF was 50％,it was better than Super-P only as conductive agents (164.4 mAh/g at 3 C),and only VGCF (155.4 mAh/g at 3 C).The electrical resistivity of the corresponding electrode was the lowest,which was 38.692 Ω · cm.关键词
