Abstract:
In this work the surface of LiNi0.5Mn1.5O4 (LMN) particles is modified by Mn3O4 coating through a simple wet grinding method, the electronic conductivity is significantly improved from 1.53×10−7 S/cm to 3.15×10−5 S/cm after 2.6 wt% Mn3O4 coating. The electrochemical test results indicate that Mn3O4 coating dramatically enhances both rate performance and cycling capability (at 55 °C) of LNM. Among the samples, 2.6 wt% Mn3O4-coated LNM not only exhibits excellent rate capability (a large capacity of 108 mAh/g at 10 C rate) but also shows 78% capacity retention at 55 °C and 1 C rate after 100 cycles.
