将本发明所述新型电容碳极性复合材料与石墨烯粉体混合在有机溶剂中，形成混合涂料；Mix the novel capacitor carbon polar composite material of the present invention and graphene powder in an organic solvent to form a mixed coating;
将所述混合涂料涂覆在金属片的表面，再通过粘结剂将所述混合涂料固定在所述金属片表面，制得电容电极。The mixed paint is coated on the surface of the metal sheet, and then the mixed paint is fixed on the surface of the metal sheet through an adhesive to prepare a capacitor electrode.
如图4所示，本实施例通过将石墨烯粉体与所述新型电容碳极性复合材料混合在一起，使得所述石墨烯粉体可以镶嵌或者分布在相邻新型电容碳极性复合材料之间，增加了相邻新型电容碳极性复合材料接触面积，从而有效提高了活性碳之间的导电性能；同时所述新型电容碳极性复合材料上的石墨烯还可以用来存储电荷。也就是说，采用本发明方法制备的电容电极既能够提升电容电极本身的导电性能，还能够有效提升其用于制备电容时的电容容量。As shown in Figure 4, this embodiment mixes graphene powder with the new capacitor carbon polar composite material, so that the graphene powder can be embedded or distributed in adjacent new capacitor carbon polar composite materials. The contact area between adjacent new capacitive carbon polar composite materials is increased, thereby effectively improving the conductivity between activated carbons; at the same time, the graphene on the new capacitive carbon polar composite material can also be used to store charges. That is to say, the capacitor electrode prepared by the method of the present invention can not only improve the conductive performance of the capacitor electrode itself, but also effectively improve its capacitance capacity when used to prepare capacitors.

在一些实施方式中，所述新型电容碳极性复合材料的粒径为150-250目。在本实施例中，若新型电容碳极性复合材料的粒径太小(大于250目)，则容易破坏活性碳内的很多孔洞，造成比表面积过小，不适合制作成电容电极材料；若新型电容碳极性复合材料的粒径太大(小于150目)，则相邻新型电容碳极性复合材料之间的接触不会十分紧密，也就是说，相互之间还有很多间隙，会影响电极的导电能力。In some embodiments, the particle size of the novel capacitive carbon polar composite material is 150-250 mesh. In this embodiment, if the particle size of the new capacitor carbon polar composite material is too small (greater than 250 mesh), many pores in the activated carbon will be easily destroyed, causing the specific surface area to be too small, making it unsuitable for being made into a capacitor electrode material; if If the particle size of the new capacitor carbon polar composite material is too large (less than 150 mesh), the contact between adjacent new capacitor carbon polar composite materials will not be very close, that is to say, there will be many gaps between each other, which will Affects the conductivity of the electrode.
在一些实施方式中，所述石墨烯粉体的粒径为800-1200目。本实施例通过将石墨烯粉体与所述新型电容碳极性复合材料混合在一起，使得所述石墨烯粉体可以镶嵌或者分布在相邻新型电容碳极性复合材料之间，增加了相邻新型电容碳极性复合材料接触面积，从而有效提高了活性碳之间的导电性能。本实施例中，若采用的石墨烯粉体粒径过小(大于1200目)，则所述石墨烯粉体容易进入到新型电容碳极性复合材料的孔洞中，造成存储电荷减小，影响成品电容容量；若采用的石墨烯粉体粒径过大(小于800目)，则不能有效的分布在相邻新型电容碳极性复合材料之间，无法提升相邻新型电容碳极性复合材料之间的导电性能。In some embodiments, the particle size of the graphene powder is 800-1200 mesh. In this embodiment, graphene powder is mixed with the new capacitor carbon polar composite material, so that the graphene powder can be embedded or distributed between adjacent new capacitor carbon polar composite materials, thereby increasing the phase density. The contact area of the new capacitive carbon polar composite material effectively improves the electrical conductivity between activated carbons. In this embodiment, if the particle size of the graphene powder used is too small (greater than 1200 mesh), the graphene powder will easily enter the holes of the new capacitor carbon polar composite material, causing the stored charge to decrease and affecting Finished capacitance capacity; if the particle size of the graphene powder used is too large (less than 800 mesh), it cannot be effectively distributed between adjacent new capacitor carbon polar composite materials, and the adjacent new capacitor carbon polar composite materials cannot be improved. conductive properties between.
