Embodiment 1
[0039] A high-capacity magnesium seawater battery cuprous chloride positive pole piece forming process of the present embodiment comprises the following steps:
[0040] (1) Preparation of raw materials: take 80% cuprous chloride powder by mass fraction, then weigh 8% conductive graphite and 2% carbon nanotubes respectively by mass fraction, put them into a high-speed mixer together, and stir for 10 minutes; Add deionized water to the mixed raw materials, stir for 10 minutes, and solidify the mixed raw materials; take out the mixed raw materials, put them into the material kneading equipment, add deionized water, and knead at a low speed for 40 minutes; weigh 10% poly Tetrafluoroethylene: add polytetrafluoroethylene into the kneading equipment for kneading, and add 20% deionized water according to the mass fraction of the mixed material, and continue kneading for a certain period of time to obtain a mixture with a certain viscosity;
[0041] (2) Electrode preparation: set the o...
Embodiment 2
[0046] Raw material preparation and diaphragm preparation are the same as other steps in Example 1; except that 95% cuprous chloride powder is weighed by mass fraction, and then 2% KS-6 and 1% carbon nanotubes are weighed by mass fraction, and Fractions were weighed out of 3% PTFE.
[0047] The cuprous chloride electrode that obtains in embodiment 2 is cut into size and is 45mm*55mm*1.5mm (thick), forms the Mg-CuCl seawater battery with the magnesium alloy of the same size magnesium sheet and AZ series Mg-Al-Zn, The electrolyte is 3% sodium chloride solution, and the battery is made into a positive and negative power generation device, and the test results are consistent with those in Example 1.
Embodiment 3
[0049] Raw material preparation and diaphragm preparation are the same as the other steps of Example 1; except that 70% cuprous chloride powder is weighed by mass fraction, and then 12% SP and 3% carbon nanotubes are weighed by mass fraction, and put into research together. In the bowl, continue to grind for 40 minutes; add deionized water to the mixed raw materials, grind for 20 minutes, weigh 15% polytetrafluoroethylene according to the mass fraction, and solidify the mixed raw materials.
[0050] The cuprous chloride electrode that obtains in embodiment 3 is cut size to be 45mm*55mm*1.5mm (thick), and the magnesium alloy of magnesium sheet and AZ series Mg-Al-Zn of the same size forms Mg-CuCl seawater battery, The electrolyte is 3% sodium chloride solution, and the battery is made into a positive and negative power generation device, and the test results are consistent with those in Example 1.
