>Enhancing the Electrochemical Performances by Wet Ball ...
The introduction of structural water in cathode materials of zinc-ion batteries can reduce electrostatic interactions to promote zinc-ion diffusion. However, it is difficult to introduce structural water in MnO2 cathodes due to annealing for crystallinity. For the first time, we introduce structural water into MnO2/graphite nanocomposites by simple wet ball milling of a …

Ball milling of rye bran gave rise to similar results, with the A/X ratio of the extractable AX being considerably lower (0.51). Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE-AX levels (>70%) in wheat and rye bran within a 24 h ball-milling period.

Abstract Manganese dioxide has been recognized as the ideal cathode for the aqueous zinc ion batteries (ZIBs). Nevertheless, the poor conductivity and infinite relative volume changes limit its further practical applications. Herein, we developed a promising cathode design by ball milling of electrolytic manganese dioxide (MnO2) in the presence of graphite nanosheets.
