Title: BATTERY ASSEMBLY TECHNIQUES
Abstract:
Battery assembly techniques and a corresponding system are disclosed. In various embodiments, the battery assembly techniques include compressing battery cells and inserting the battery cells in a can. Battery cells are stacked and then compressed using pneumatic cylinders that exert pressure on a first external layer of the stacked battery cells. A first portion of the stacked battery cells is released from the pneumatic cylinders while a second portion of the battery cells remains compressed. The first portion of the stacked battery cells is inserted in a can. In various embodiments, friction decreasing materials are added to the stacked battery cells to compress the stacked battery cells or ease insertion.
