Abstract
The invention relates to a method and process apparatuses for forming a uniform carbon nano-tube electric-conduction paste. The method comprises: adding a dispersant and NMP to a planetary stirrer, and carrying out mixing stirring; adding medium-size carbon nano-tubes to the planetary stirrer, and continuously mixing and stirring, wherein the length of the medium-size carbon nano-tubes is 5-10 [mu]m, and the diameter is 10-12 nm; and sequentially adding graphene and electric-conduction carbon spheres to the planetary stirrer to form the electric-conduction paste. According to the present invention, the electric-conduction paste is fed to a stirring grinding mechanism, wherein the stirring grinding mechanism comprises another planetary stirrer and a wet grinder connected in series with theplanetary stirrer; and filling the planetary stirrer with the electric-conduction paste, and making the electric-conduction paste cyclically flow between the planetary stirrer and the wet grinder by acirculating conveying mechanism.
Description
technical field [0001] The invention relates to the field of manufacturing carbon nanotube conductive paste, in particular to a method for forming uniform carbon nanotube conductive paste and an applied process device. Background technique [0002] The battery is mainly formed by placing the positive electrode and the negative electrode in the electrolyte solution. Wherein the positive electrode is to mix and disperse a large number of positive electrode conductive units (positive electrode material, such as lithium cobalt oxide) in the slurry. Generally speaking, the positive conductive unit must be mixed with the conductive paste before it can be applied to the electrode sheet and assembled into a battery. Therefore numerous positive electrode conductive units (positive electrode materials) are connected to each other by conductive paste, so the conductive paste must have conduction aid or conductivity, so that free electrons can migrate in different positive electrode co...
