Electrolytic MnO2 via non-isothermal electrode heating: a promising approach for optimizing performances of electroactive materials

Electrolytic manganese dioxide (EMD): a perspective on worldwide production, reserves and its role in electrochemistry

“…99 Based on Preisler's 99 observation Ti seems to be a very attractive anode material and has been used for EMD deposition by many researchers. 109 Kebadze et al 111 synthesized EMD on brous carbon electrodes as cathodes and anodes and observed that use of these electrodes improved process parameters (materials consumption, current density, specic electric power) for the electro-synthesis of MnO 2 . 108 The authors discussed the nature of the anode material which is responsible for its service life and the electrolytic parameters for the purity of EMD.…”

Influence of the solution pH on the nanostructural, and electrochemical performance of electrolytic manganese dioxide

“…The 10% ammonia solution was previously used as a neutralized the EMD after electrodeposition [8], therefore, it is used as a pH-stabilizing agent in this work. The XRD patterns of the obtained powders are illustrated in Fig.…”

“…Both ␣-MnO 2 and ␤-MnO 2 show low electrochemical activity when used as active material. Therefore, the electrochemical performance of MnO 2 , as active material in supercapacitors, Li-ion and rechargeable alkaline manganese dioxide (RAM) batteries, is strongly affected, but in proportion to the contribution of ␣ or ␤ in MnO 2 [4][5][6][7][8][9][10][11][12].…”

Spectral and electrochemical behavior of manganese dioxide nanodispersions prepared in reverse micelle

“…The catalytic activity and the selectivity of the material have been found to be dependent on porosity or grain size. So many routes for preparation of MnO 2 have been followed which include both electrochemical [17][18][19][20] and chemical [21][22][23][24][25] means. The grain size can be conveniently controlled for a water-insoluble material by synthesizing it in the aqueous core of a reverse micelle via a reaction between two water-soluble species, because the size of the water pool micro-reactor can be varied by changing the ratio (x) of the concentrations of water and surfactant.…”
