Abstract :
LiCr0.15Mn1.85O4 spinel has been successfully synthesized by glycine–nitrate method (GNM). The presence of pure spinel phase was confirmed by long term XRPD measurements and the Rietveld structural refinement. Lattice parameter was estimated to be 8.2338 Å. Average particle size of prepared powder material is below 500 nm. The BET surface area is 9.6 m2 g− 1. As a cathode material for lithium batteries LiCr0.15Mn1.85O4 shows initial discharge capacity of 110 mA h g− 1 and capacity retention of 83% after 50 cycles.
