摘要： The disclosure includes an electrochemical cell comprising a first cathode and a second cathodes are adjacent one another in a stacked arrangement to form a cathode stack in the electrochemical cell. The first cathode includes a first current collector and a first cathode form of active material covering the first current collector, and the second cathode includes a second current collector and a second cathode form of active material covering the second current collector. The second current collector is in electrical contact with the first current collector. The electrochemical cell further comprises an anode adjacent to the cathode stack, and a separator located between the cathode stack and the anode.

摘要： An electrode assembly in embodiments of the invention can include a unitary member formed from an electrically conductive material having a central portion, and tab and plate portions extending radially outward from the central portion. The unitary member can be folded to configure the plate portions in a stacked configuration, thereby providing an electrically connected support structure for a cathode and/or anode assembly without individual connections/welds of plates to a common connection. The elimination of multiple welds lowers the internal resistance of the electrode assembly, and improves the structural integrity. Embodiments of the invention include batteries and implantable medical devices (IMDs) which incorporate the design flexibility in the shape and contour of the electrode assembly and hence, the overall shape and design of batteries and IMDs.
摘要翻译：在本发明的实施例中的电极组件可以包括由具有中心部分的导电材料形成的整体构件，以及从中心部分径向向外延伸的凸片和板部分。可以将整体构件折叠以将板部分构造成堆叠构型，从而为阴极和/或阳极组件提供电连接的支撑结构，而不需要将板与各公共连接的单独连接/焊接。消除多个焊缝会降低电极组件的内部电阻，并提高结构完整性。本发明的实施例包括电池和可植入医疗装置（IMD），其将电极组件的形状和轮廓的设计灵活性并入电池和IMD的整体形状和设计。

摘要： Provided is an electric storage battery including a jelly roll type electrode assembly having a mandrel. The mandrel includes a positive portion, a negative portion and a removable portion. In some embodiments, the mandrel is planar having two faces with a groove on each of the positive and negative portions. The grooves can be on the same or different faces of the mandrel. The grooves are dimensioned to accommodate a positive and negative feedthrough pin. The electrodes are wrapped around the mandrel using the removable portion to wind the mandrel. Once wrapped, the removable portion can be detached. The positive portion and the negative portion are left in the electrode assembly insulated from each other. The mandrel allows tighter wrapping of the jelly roll assembly, increasing battery miniaturization and also results in electrode assemblies in which after-placement of tabs does not result in burrs or shorting.
摘要翻译：提供一种蓄电池，其包括具有心轴的果冻辊型电极组件。心轴包括正部分，负部分和可移除部分。在一些实施例中，心轴是平面的，具有在正和负部分中的每一个上具有凹槽的两个面。凹槽可以在心轴的相同或不同的面上。凹槽的尺寸适于容纳正和负的馈通销。使用可移除部分将电极缠绕在心轴上以卷绕心轴。一旦被包裹，可移除部分就可以拆卸。正极部分和负极部分保留在彼此绝缘的电极组件中。心轴允许果冻辊组件更紧密地包裹，增加电池的小型化，并且还导致电极组件，其中片的后置放置不会导致毛刺或短路。
