“…NMD has thus been replaced with synthetic electrolytic manganese dioxide (EMD) of γ-MnO2 form. The salient features of EMD are its low production cost, low environmental impact, high redox potential, high rate capability, better relative performance over a wide temperature range, and long storage life [5][6][7][8][9][10]. Although γ-MnO2 can be produced by a number of different routes, electrolytically produced γ-MnO2 is the most suitable for battery applications due to its low polarization [11], and it has a niche in the market.…”

“…EMD has a high redox potential, high rate capability, long storage life, and better performance over a wide temperature range relative to its nickel and cobalt counterparts. [4][5][6][7][8] It is anticipated that over the next decade, the pricing for high purity EMD will increasingly be affected by the demand for lithium-ion batteries containing cathodic material derived from EMD. This rechargeable battery has quickly become the technology of choice in the cordless power tool industry and is being increasingly applied in the electric vehicle (EV) and hybrid electric vehicle (HEV) industries.…”

The effect of non-ionic surface active agents (surfactants) Triton X-100 (TX-100) and and their role in potassium intercalation in electrolytic manganese dioxide (EMD) produced from manganese cake has been investigated. Electrosynthesis of MnO 2 in the absence or presence of surfactant was carried out from acidic MnSO 4 solution obtained from manganese cake under optimized conditions. A range of characterization techniques, including field emission scanning electron microscopy, transmission electron microscopy (TEM), Rutherford back scattering (RBS), and BET surface area/porosity studies, was carried out to determine the structural and chemical characteristics of the EMD. Galvanostatic (discharge) and potentiostatic (cyclic voltammetric) studies were employed to evaluate the suitability of EMD in combination with KOH electrolyte for alkaline battery applications. The presence of surfactant played an important role in modifying the physicochemical properties of the EMD by increasing the surface area of the material and hence, enhancing its electrochemical performance. The TEM and RBS analyses of the discharged EMD (c-MnO 2 ) material showed clear evidence of potassium intercalation or at least the formation of a film on the MnO 2 surface. The extent of intercalation was greater for EMD deposited in the presence of TX-100. Discharged MnO 2 showed products of Mn 2+ intermediates such as MnOOH and Mn 3 O 4 .

“…22,[40][41][42][43][44] Being an environmentally benign and relatively inexpensive material manganese dioxide has been in high demand as a cathode material for energy storage when compared to other metal oxide counterparts such as nickel 45 and cobalt-oxides. Since 1990s, it has also become very popular in lithium, sodium and magnesium-ion rechargeable batteries.…”
