N‐doped carbon‐coated CoSe2 nanocrystals anchored on two‐dimensional MXene nanosheets for efficient electrochemical sodium‐ and potassium‐ion storage

Summary Sodium‐ion batteries (SIBs) and potassium‐ion batteries (KIBs) have received much attention as next‐generation energy storage systems owing to the abundance. Nevertheless, they face great challenges in the design of optimum electrode materials for practical applications. Herein, we prepared...
