Electrochemical pouch cell for energy storage devices

Disclosed is an electrochemical pouch cell (1), particularly intended for an electrical energy storage device (10) of a motor vehicle, comprising a stack of a plurality of electrodes (2), at least one electrical terminal (4), and an inner liner (3) connected to the electrical terminal (4) and itself at a primary connection (5) and a secondary connection (6), respectively, so as to form a recess (100), the plurality of electrodes (2) and all or part of the at least one electrical terminal (4) extend into the recess, a first dimension of the electrical terminal (4) being substantially equal to or greater than a first dimension of a stack of the plurality of electrodes (2). 披露了一种尤其旨在用于机动车辆的电能储存设备(10)的电化学软包电池单体(1)，该电化学电池单体包括由多个电极(2)构成的堆叠、至少一个电端子(4)、以及内衬(3)，该内衬分别在主连结部(5)和副连结部(6)处连接到电端子(4)和自身，以便形成凹部(100)，该多个电极(2)和整个或部分的该至少一个电端子(4)延伸到该凹部中，电端子(4)的第一尺寸基本等于或大于由该多个电极(2)构成的堆叠体的第一尺寸。
