Urea-assisted mixed gas treatment on Li-Rich layered oxide with enhanced electrochemical performance

Lithium-rich manganese-based oxides (LRMOs) have been considered as one of the most promising cathode materials owing to their superior specific capacity and high operating voltage. However, their large-scale commercial applications are limited due to problems such as structural instability, voltage decay, and poor cycle stability. Herein, pre-generated oxygen vacancies and oxygen-deficient phase were introduced to Li 1.2 Mn 0.6 Ni 0.2 O 2...
