Abstract

In situ electrochemical formation of a high capacity electrode material which depends on the use of divided MnO powders and does not require the ball milling process on MnO-LiF composites is reported. The reactivity of MnO with electrolyte salt is fixed in the electrochemical-driven catalytic decomposition of LiPF₆ and show the feasibility of preparing MnO electrodes with room temperature capacity over 300 mA h/g^-1 good cycling performances and capability of delivering 75% of their initial energy density at C/5 rate. The study primarily aimed to show how to turn the decomposition of LiPF₆ which is extremely harmful to Li-ion batteries to the advantage of designing novel high energy density materials in situ.
