Soft chemical synthesis and electrochemical properties of calcium ferrite-type LixMn2O4

The reference CaFe2O4-type LiMn2O4 was prepared via one-step high-pressure synthesis and compared the electrochemical properties with the ion-exchanged sample. The initial discharge capacity of the one-step synthesized one was 108 mAh g−1 at 1.0 V (vs. Li/Li+), which was 73% lower than the value of the ion-exchanged one.
