14-18 parts of zinc powder;
0.008-0.012 parts of indium oxide;
0.06-0.09 part of polyacrylic acid;
0.06-0.09 part of sodium polyacrylate;
6-7 parts of electrolyte;
1.2 to 1.5 portions of deionized water.
The preparation method of the cathode material for the mercury-free alkaline zinc-manganese dioxide battery comprises the following steps:
firstly, putting zinc powder, indium oxide, polyacrylic acid and sodium polyacrylate together, stirring for 25-35 minutes, and uniformly mixing to prepare a mixture;
and pouring the electrolyte, the deionized water and the mixture into a paste mixing machine, and stirring for 35-45 minutes under vacuum to obtain the mercury-free alkaline zinc-manganese dioxide battery cathode material.
