Further Utilization of a Mn Redox Reaction Via Control of Structural Disorder in Olivine Systems

Anti-site defects are a critical factor for improving the electrochemical performance of olivines, and these defects can be decreased by introducing non-stoichiometry in the crystal structure that enables selective further oxidation of Mn in LiFe0.5−xMn0.5−xPO4−σ type olivine systems.
