nLi_xMn_2-yO₄ Cells - Secondary Performance

Results of cyclng a Li-nLiMn₂O₄ cell between 4.5 and 2.5 V at a rate of 20 µA/cm².

The capacity loss is about 0.003% per cycle.

Results of continued cycling at 100°C. The higher capacity loss is due to a recrystallization of the cathode.

Increasing crystallinity of the cathode with cycling leads to a gradual change in the discharge curve.
