Retarding the capacity fading and voltage decay of Li-rich Mn-based cathode materials <i>via</i> a compatible layer coating for high-performance lithium-ion batteries

Abstract

coating with oxygen vacancies could inhibit the loss of lattice oxygen and protect the electrode surface by suppressing the attack from the electrolyte. This work provides an effective approach to design Li-rich Mn-based layered oxides with improved electrochemical performance.
