本发明为种透明柔性超级电容器的制备方法。该方法以金属纳米线溶液为原料，通过旋涂法在透明柔性基底材料的表面制备得到表面覆盖金属纳米线网络的透明柔性集流体；并通过沉积法将石墨烯等含碳材料实现透光率、均匀度可控制的沉积到PET极片上；再将两片极片通过轧制，得到了"三明治"结构的双电层透明柔性超级电容器。本发明技术路线简单，得到的活性材料具有开放三维(多级)结构，在降低了超级电容器系统内阻同时，保持高透光率，使能量和功率密度达到最优化。 The invention relates to a method for preparing a transparent flexible supercapacitor. According to the method, with a metal nanowire solution as a raw material, preparation is carried out on the surface of a transparent flexible substrate material by a spin-coating method to obtain a transparent flexible collector with the surface covered with a metal nano wire network; on the basis of a deposition method, carbon-included materials like graphene are deposited on PET polar pieces in a light transmittance and uniformity controllable manner; and then the two polar pieces are rolled to obtain a double-electricity-layer transparent flexible super capacitor with a sandwich structure. The technical route is simple; the obtained active material has an open three-dimensional (multi-stage) structure; the
