Thermodynamic Activation of Charge Transfer in Anionic Redox Process for Li‐Ion Batteries

Rechargeable lithium-ion batteries with high energy densities are indispensable for the further development of portable electronics and electric vehicles. Traditional cathode electrodes based on materials such as LiCoO2, LiFePO4, and LiMn2O4 operate by reversible intercalation and extraction with restricted numbers of lithium ions during charge and discharge, respectively, resulting in limited specific capacities that cannot meet the demands of high-energy-density batteries.
