Example Embodiment
[0066] Example 1:
[0067] A water-soluble conductive nano-metal carbon slurry, characterized in that: the water-soluble conductive nano-metal carbon slurry comprises a water-soluble nano-metal solution with a particle size range of 10-60 nanometers and a concentration of 0.05-8 g / L. A water-soluble nano-scale conductive carbon black solution of 100-1000 nanometers and a concentration of 10-50 g / L; the water-soluble nano metal solution and the water-soluble nano-scale conductive carbon black solution are mixed in a ratio of 1:100, After adding water and at least 5 kinds of surfactants with a concentration of 0.5-10 g / L and an organic reducing agent with a concentration of 0.05-1 g / L, use a grinder to grind and disperse the nano metal powder particles into the carbon black Within the particles, the water-soluble conductive nano-metal carbon paste is formed.
Example Embodiment
[0068] Example 2:
[0069] The difference between this embodiment and embodiment 1 is: the particle size of the nano metal powder is 15-50 nanometers; the particle size of the nano-scale conductive carbon black is 180-950 nanometers; the surfactant includes a wetting agent, Penetrant, dispersant, polymer barrier agent, thixotropic agent, defoamer.
Example Embodiment
[0070] Example 3:
[0071] The difference between this embodiment and Embodiment 1 is that the grinder is a vertical, horizontal, or basket sand mill.
