Embodiment Construction
[0021] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] Such as figure 1 As shown, the first embodiment of the present invention proposes a method for preparing a novel powder aluminum positive electrode material for aluminum electrolytic capacitors, comprising the following steps:
[0023] Step S100, using spherical aluminum powder with a particle size between 50 nanometers and 100 microns as the main raw material, using one of ethanol, ethyl acetate, acetone, and special epoxy resin as a dispersing solvent and binder, and spherical aluminum powder The aluminum powder is pre-mixed, wherein the weight of the solvent accounts for 0.1-0.5 of the weight of the aluminum powder. Specifically, the prepared spherical aluminum powder with a certain particle size is mixed with different mixing and dispersing binding solvents.
[0024] Step S200, after the pre-mixed spheric...
