Abstract:
A MnO2 electrode active material of high capacity is provided. The high capacity MnO2 has a surface area which is greater than 60 m2/g and the MnO2 is obtained by a process comprising a redox reaction of a Mn (II) salt and permanganate at a reaction temperature less than 30° C. and a pH of 2 to 4. Also provided are a magnesium electrochemical cell having a cathode containing the MnO2 and a rechargeable magnesium battery having a cathode containing the MnO2.
