Embodiment 1
[0035] (1) At 25°C, the graphene conductive paste was subjected to back-type vibration for 30 minutes on a vibration machine with a vibration frequency of 200rmp and an amplitude of 25.0mm to remove the upper layer solution, and then sprayed on the positive plate by 0.04MPa high-pressure spraying The graphene conductive paste is evenly sprayed on the front and back sides of the grid and the negative grid, so that the frames and horizontal and vertical ribs of the positive grid and the negative grid are covered with graphene layers. Dry the kiln for 30 seconds to form a graphene coating.
[0036] (2) The positive lead paste has the following components by mass: lead powder 95Kg, dilute sulfuric acid 11Kg, red lead 4Kg, antimony trioxide 0.2Kg, stannous sulfate 0.2Kg, graphene conductive paste 0.05Kg, short fiber 0.1 Kg, 9Kg of pure water; the positive electrode paste is mixed according to the above steps, wherein the apparent density of the positive electrode paste is 4.40g / cm ...
Embodiment 2
[0041] (1) At 25°C, the graphene conductive paste was subjected to back-type vibration for 30 minutes on a vibration machine with a vibration frequency of 200rmp and an amplitude of 25.0mm to remove the upper layer solution, and then sprayed on the positive plate by 0.04Mpa high-pressure spraying The graphene conductive paste is evenly sprayed on the front and back sides of the grid and the negative grid, so that the frames and horizontal and vertical ribs of the positive grid and the negative grid are covered with graphene layers. Dry the kiln for 30 seconds to form a graphene coating.
[0042] (2) The positive lead paste has the following components by mass: 95Kg of lead powder, 11Kg of dilute sulfuric acid, 4Kg of red lead, 0.2Kg of antimony trioxide, 0.2Kg of stannous sulfate, 0.2Kg of graphene conductive paste, and 0.1 kg of short fiber Kg, 9Kg of pure water; the positive electrode paste is mixed according to the above steps, wherein the apparent density of the positive e...
