Triggering the In Situ Electrochemical Formation of High Capacity Cathode Material from MnO

An in situ way to prepare manganese-based high capacity cathode material is proposed by directly cycling MnO with conductive carbon in LiPF6-based electrolyte. An easily scalable process involving 2 h high-energy ball milling of the mixture is adopted. A fluorine-rich environment enabled by electrochemical-driven catalytic decomposition of LiPF6 is found to be essential to sustain the reversible reaction.
