The implementation of spinel LiMn 2 O 4 in lithium-ion batteries has been long established
commercially and well-reported academically. Nowadays, most commercial spinel LiMn 2 O …

The oxygen reduction reaction (ORR) was studied in KOH electrolyte on carbon supported
epsilon-manganese dioxide (ɛ-MnO2/C). The ɛ-MnO2/C catalyst was prepared via thermal …

Intercalation of alkali cations (Na+, K+, etc.) or protons (H+) on the surface of MnO 2 can
improve the theoretical pseudocapacitance in the redox reactions. However, the poor …

Non-precious metal bifunctional oxygen reduction and oxygen evolution reaction (ORR and
OER, respectively) catalysts are of great interest for rechargeable metal/air batteries and …

Nanostructured manganese oxides, eg MnO2, have shown laccase-like catalytic activities,
and are thus promising for pollutant oxidation in wastewater treatment. We have …

With the deepening application of manganese based cathode materials in new energy
vehicle power batteries and wind solar energy storage batteries, diversified application …

A systematic study of the effect of acid concentration (0.5–5 MH 2 SO 4) on the electrolysis of
electrolytic manganese dioxide (EMD or γ-MnO 2) has been performed. All the samples …

Resumo The< FONT FACE=" Symbol"> e</font> phase of electrolytic manganese dioxide
