Abstract：LiNi0.5Co0.2Mn0.3O2， the eligible ternary cathode materials of lithium ion batteries， were synthesized by sol-gel self propagating combustion method using waste NiCoMn ternary material as raw material. The composite was characterized by TG， XRD， SEM and land testing. The results indicate that the material not only has a good layered structure， but also has porous properties. The discharge capacity of the product synthesized at pH＝8 is 164.6 （mA·h）/g in 2.75-4.30 V at 0.2 C， the coulomb efficiency is about 85.8%， and the capacity retention rate is about 94.9% after 30 cycles. This material is an excellent ternary cathode material with high discharge specific capacity.
