The key finding was that for compositions more reduced than ~MnO₁․₈₀, structural expansion has caused mechanical degradation of individual particles, as well as caused porosity changes within individual manganese dioxide particles and the electrode itself, essentially making them unavailable for discharge (proton insertion). A further implication of this is that the performance of the alkaline manganese dioxide cathode is then predominantly dependent on the geometric surface area and the bulk γ-MnO2 structure.]]> Wed 11 Apr 2018 13:49:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3213 50 Hz) and low (<2 Hz) frequency EIS data, was able to be interpreted in terms of changes in both the manganese dioxide and electrode porosity, as well as mechanical degradation of the manganese dioxide itself.
