A method for preparing a Kevlar nanofiber enhanced flexible solid linear supercapacitor is disclosed. The invention relates to a method for preparing a supercapacitor, to solve the problem that in the prior art, the gel used in preparing all-solid-state linear supercapacitor is poor in mechanical property, and that mechanics strength is limited with the material toughness as a cost when a method of generating cross-linked polymer is used to improve the mechanical property of gel polymer. The method includes the steps of 1) preparing Kevlar nanofibers, 2) assembling a capacitor, 3) preparing electrolyte, 4) filling electrolyte, and 5) drying the capacitor. The invention is applicable to a method for preparing Kevlar nanofiber enhanced flexible solid linear supercapacitor. 种凯夫拉纳米纤维增强柔性固态线状超级电容器的制备方法，本发明涉及超级电容器的制备方法。本发明要解决现有技术存在制备全固态线状超级电容器使用的凝胶机械性能低，通过生成交链聚合物的方法提高凝胶聚合物的机械性能，但力学强度仍然有限并且常以牺牲材料韧性为代价的问题。方法：、凯夫拉纳米纤维的制备；二、电容器的组装；三、电解质的制备；四、电解质的灌注；五、电容器的干燥。本发明用于种凯夫拉纳米纤维增强柔性固态线状超级电容器的制备方法。
