The method discloses a method for preparing a supercapacitor electrode based on a silver nanowire. The method comprises the following steps: using the silver nanowire as a conductive agent, mixing with a binder and an active substance to prepare a sizing agent, using foamed nickel as a current collector to prepare an electrode piece through a rolling or coating transfer technology, combining a diaphragm and an electrolyte or ionic liquid to assemble a supercapacitor; in the supercapacitor, the silver nanowire is used as the conductive age3nt to replace a traditional conductive agent, and the supercapacitor is excellent in performance, high in repeatability and low in cost and has wide application prospect. 本发明公开了种基于银纳米线制备超级电容器电极的方法；应用银纳米线作为导电剂，和粘结剂及活性物质混合配制浆料，通过滚压或涂布转移工艺技术以泡沫镍为集流体制备成电极极片，结合隔膜和电解液或离子液体，组装成超级电容器；该超级电容器应用银纳米线作为导电剂，取代传统导电剂，超级电容器性能优异、重复性好、成本低，具有广泛的应用前景。
