Rational design of Na(Li1/3Mn1/2Cr1/6)O2 exhibiting cation–anion-coupled redox reactions with superior electrochemical, thermodynamic, atomic, and chemomechanical properties for advanced sodium-ion batteries

Based on a cation–anion-coupled redox paradigm, Na(Li_1/3Mn_1/2Cr_1/6)O₂ is systematically designed to use rational anion redox reactions (O²⁻/O⁻) for high energy density cathodes in sodium-ion batteries.
