Gradient V2O5 surface-coated LiMn2O4 cathode towards enhanced performance in Li-ion battery applications

Gradient V2O5 surface-coated LiMn2O4 particles with size distribution of 100 - 500 nm and excellent performance in lithium-ion battery were prepared via a simple method, and the amount of V2O5-coating was initially proved to be a critical parameter for improving the properties of LiMn2O4.
