Example Embodiment
[0015] Example 1
[0016] The first step is the preparation of electrolytic manganese dioxide:
[0017] The electrolyte is a manganese sulfate solution, the mass concentration of manganese sulfate is 135g / L, the pH value is 3.9, the electrolyte temperature is 90℃, the titanium alloy is used as the anode, the carbon electrode is the cathode, and the current density is 10mA / cm 2 , The deposit from the anode is washed, neutralized, ground and dried to obtain electrolytic manganese dioxide.
[0018] The second step is the preparation of powder porous manganese dioxide electrode:
[0019] Dry and mix electrolytic manganese dioxide and expanded graphite uniformly, the mass ratio of the two is 80:20, and then add the binder (sodium carboxymethyl cellulose aqueous solution) dropwise and stir until it becomes a paste. The body is smeared on both sides of a 3cm×3cm titanium mesh, compacted and dried to obtain a powder porous manganese dioxide electrode.
