Abstract

The LiMn₂O₄ powder was prepared by Sol-gel method at 300℃. The morphology and size of grain were determined by XRD and SEM. Coin cells have been used to test the cycleability and characteristics the materials with 1 mol LiCLO₄/PC-EC-DME electrolyte. Reversible capacity has been demonstrated for 10 cycles with 125 mAh/g in the range 4.2 V to 3.4 V cycling cut off voltages without any important capacity loss.
