Assembling method of all-solid-state battery and all-solid-state battery

The invention provides an assembly method of a solid-state battery and an all-solid-state battery. The method comprises the following steps: providing an elastic auxiliary film; assembling the elastic auxiliary membrane, the positive plate and the electrolyte layer into a first structural body; performing first cold pressing on the first structural body to obtain a second structural body; assembling the negative plate and the second structural body to obtain a third structural body; and performing second cold pressing on the third structural body to obtain the all-solid-state battery. By adopting the technical scheme of the invention, the problems of easy short circuit of the battery and poor cycle performance of the battery cannot be simultaneously solved when the solid-state battery is assembled in the prior art are effectively solved. 本发明提供了一种固态电池的组装方法及全固态电池，方法包括：提供弹性辅助膜；将弹性辅助膜、正极片和电解质层组装为第一结构体；对第一结构体进行第一冷压，得到第二结构体；将负极片与第二结构体进行组装，得到第三结构体；对第三结构体进行第二冷压，得到全固态电池。采用本申请的技术方案，有效地解决了现有技术中在组装固态电池时无法同时解决电池易短路和电池循环性能
