摘要
Abstract
The relative scarcity of domestic cobalt resources,mostly relying on imports,de-cobaltization has become one of the future development directions of ternary cathode materials for lithium-ion batteries.In this study,high-nickel cobalt-free LiNi0.9Mn0.1O2 binary single crystal cathode material and cobalt-containing LiNi0.92Co0.06Mn0.02O2 ternary single crystal cathode material were taken as the objects of study,and the electrochemical performances such as specific capacity,initial DCR,rate and cycling of the two materials were characterized using CR2016 button half battery and 604062 soft pack full battery respectively.The feasibility of the high-nickel cobalt-free binary single crystal cathode material in the application of lithium-ion batteries was investigated.The experimen-tal results show that although the specific capacity of high-nickel cobalt-free LiNi0.9Mn0.1O2 binary single crystal cathode material is slightly lower than that of cobalt-containing LiNi0.92Co0.06Mn0.02O2 ter-nary single crystal cathode material,it has obvious advantages in terms of cycle stability.And it can be used as one of the substitutes of the cobalt ternary cathode material when the price of cobalt is un-stable in the future.关键词
