Core-shell structure of LiMn2O4 cathode material reduces phase transition and Mn dissolution in Li-ion batteries
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 re...

| description | 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. |
