摘要
Abstract
In order to improve the cycle stability of LiNi0.8 Co0.1 Mn0.1 O2(NCM811)material,a simple method was used to prepare functional electrolyte with aluminum oxide(Al2 O3)as the electrolyte treatment agent,its effect on the performance of NCM material was studied.Compared with the original NCM,the NCM with 0.50%Al2O3 added to the electrolyte in 2.75-4.30 V at 0.5 C for 200 cycles,the capacity decay was slower,the capacity retention rate was 80.33%,the charge transfer resistance(Rct)increase trend was lower.The SEM analysis showed that clear particle profile and layered structure could still be seen on the cathode surface.关键词
