Abstract

本申请公开了一种电极组件及电池单体、电池、装置、制备方法和制备装置。该电极组件包括至少两个极片，包括极性相反的第一极片和第二极片，所述第一极片和所述第二极片绕卷绕轴线卷绕形成多层结构，所述多层结构具有沿所述卷绕轴线的方向延伸的容纳腔，所述容纳腔用于容纳电解液；其中，所述电极组件还包括沿第一方向延伸的至少一个导流通道，所述第一方向为垂直于所述卷绕轴线的方向，所述导流通道被配置为引导所述容纳腔内的电解液向外排出。通过设置导流通道作为电解液的传输通道，使得容纳腔内的电解液既可以通过第一极片和第二极片中的间隙向外排出，还可以通过导流通道向外排出，从而改善电解液在电极组件中的浸润效果。
