a The SEM image of the as-prepared Li2MnO3 powder. The as-prepared Li2MnO3 exhibits a single-particle morphology with average particle size of 100–200 nm. b The nitrogen adsorption/desorption isotherm of the as-prepared Li2MnO3 powder. c The corresponding BET plot of the as-prepared Li2MnO3 powder. The specific surface area of Li2MnO3 is calculated to be 3.1106 m2 g−1. d The particle size distribution of the as-prepared Li2MnO3 powder. e In situ DEMS for the first charge of Li2MnO3. The signal of O2 evolution is not detected until 20% delithiation of Li2MnO3.
