Its high nominal voltage, thermal stability, and low toxicity render LiMn2O4 a highly promising cathode material for lithium ion batteries, but capacity fading due to unwanted side reactions during cycling remains an issue. Here, the authors show that carbon-coating a LiMn2O4 cathode reduces side reactions such as manganese dissolution and manganese oxide formation, thereby improving battery cycling stability.
