Carbon materials for stable Li metal anodes: Challenges, solutions, and outlook

Abstract Lithium (Li) metal is regarded as the ultimate anode for next‐generation Li‐ion batteries due to its highest specific capacity and lowest electrochemical potential. However, the Li metal anode has limitations, including virtually infinite volume change, nonuniform Li deposition, and an unst...
