Abstract: Energy storage devices, battery cells, and batteries may include a first current collector having an anode active material disposed along a first surface of the first current collector. The cells may include a plurality of first electrodes positioned along a second surface of the first current collector opposite the first surface. The plurality of first electrodes may be characterized by a first orientation. The cells may include a second current collector having a cathode active material disposed along a first surface of the second current collector. The cells may include a separator positioned between the anode active material and the cathode active material. The cells may also include a plurality of second electrodes positioned along a second surface of the second current collector opposite the first surface. The plurality of second electrodes may be characterized by a second orientation substantially orthogonal to the first orientation.

Abstract: The disclosed embodiments relate to the design of a jelly-roll battery comprising an alternating anode and cathode layers coated with intervening separator layers wound into a jelly-roll. The alternating anode and cathode layers are coated with, respectively, an anode active coating and a cathode active coating. A first common notch and a second common notch are formed along at least one side of the jelly-roll. A common cathode tab can be bonded to the cathode tabs within the first common notch, and a common anode tab can be bonded to the anode tabs within the second common notch. The jelly-roll battery also includes a pouch enclosing the jelly-roll. Common anode and cathode tabs can extend through the pouch to provide cathode and anode terminals for the battery cell.

Abstract: The described embodiments relate to methods and apparatus for improving pick and place operations. Pick and place operations involving the movement of flexible substrates can be improved by cooling a flexible substrate below a threshold temperature at which the flexible substrate transitions from a flexible state to a rigid state. Once in the rigid state, the flexible substrate can be handled and maneuvered by pick and place operations for a period of time with a limited risk of the flexible substrate wrinkling and tearing. In some embodiments, the flexible substrate is a thin polymeric substrate used to separate oppositely charged battery cells within a battery assembly.

Abstract translation: 所描述的实施例涉及用于改善拾取和放置操作的方法和装置。 可以通过将柔性基底冷却到柔性基板从柔性状态转变到刚性状态的阈值温度以下来改善涉及柔性基板移动的拾取和放置操作。 一旦处于刚性状态，柔性基底可以通过拾取和放置操作来处理和操纵一段时间，其柔性基底起皱和撕裂的风险有限。 在一些实施例中，柔性基底是用于分离电池组件内的相反电荷的电池单元的薄聚合物基底。
