摘要： The invention provides a high-speed manufacturing technology for producing a stack for a secondary battery. The stack manufacturing apparatus (1) creates a stack (2) that includes a band-shaped separator (S) folded in a zigzag manner and electrode sheets alternately stacked with the separator in between. The apparatus features a transfer robot (12) that sequentially places negative electrode sheets (91) on a placement table (41), a mechanism for arranging positive electrode sheets (92) in a standby position, a separator supply unit (30) to supply the separator without slack, and a rotary chuck mechanism (43) with two chucks (432) that hold and transfer the positive electrode sheet (91) and separator (S) together onto the stack. The free part of the separator is controlled to match the width of the electrode sheets.

摘要： Provided in the embodiment of the present application are an electrode assembly, a battery cell, a battery, and an electric apparatus. The electrode assembly comprises a positive electrode plate, a negative electrode plate, and a separation assembly, wherein the separation assembly is configured to separate the positive electrode plate from the negative electrode plate. The separation assembly comprises a substrate area and a reinforcing area connected to the substrate area, a thickness of the reinforcing area being greater than a thickness of the substrate area. At least part of the reinforcing area is located between the positive electrode plate and negative electrode plate adjacent to each other. The reinforcing area may be configured to correspond to a position where the negative electrode plate is prone to lithium precipitation. In this way, when lithium precipitation occurs on the negative electrode plate, the reinforcing area can effectively separate the positive electrode plate from the negative electrode plate, thereby reducing the risk of lithium dendrites passing through the separation assembly, prolonging the service life, and improving the safety. Compared with the reinforcing area, the substrate area may have a relatively small thickness, so that the amount of separation assemblies can be reduced, the cost is reduced, and energy density of the electrode assembly is increased.

摘要： Um umwickelte Zellstapel in Großserie schneller und dennoch prozesssicher herzustellen, schafft die Erfindung ein Verfahren und eine Vorrichtung (24) zur Herstellung z-gefalteter Zellstacks (10). Damit werden erste und zweite Zellkomponenten (12, 14) wechselweise gestapelt, während eine Separatorbahn (26) z-förmig oder mäanderförmig dazwischen eingefügt wird und anschließend um den so erhaltenen Zellstapel (10) noch einmal gewickelt wird. Das Verfahren und die Vorrichtung sind so ausgebildet, dass das Wickeln zumindest teilweise parallel an einem zuvor erhaltenen Zellstapel (10) durchgeführt wird, während das Stapeln zum Erhalten des nächsten Zellstapels (10) durchgeführt wird.
