摘要： Systems, methods, and other implementations described herein relate to a battery for use in a battery cell assembly that facilitates pack manufacturing. In one embodiment, the battery cell assembly includes a first battery cell having two electrical tabs extending from the first battery cell. The battery cell assembly also includes a second battery cell positioned substantially adjacent to the first battery cell and having two electrical tabs extending from the second battery cell. Additionally, the electrical tabs of the first and second battery cells are prebent. The battery cell assembly further includes a busbar operatively connected to the electrical tabs of the first and second battery cells.

摘要： A battery module having a battery cell assembly that is free from module banding is provided. The assembly includes an expandable battery cell having a first and second face. The assembly further includes a growth plate having a first and second face. The first face of the battery cell contacts the second face of the growth plate. The battery cell assembly further includes a first cell frame securing the growth plate on at least two sides and a second cell frame that contacts the second face of the battery cell. The first face of the growth plate includes a plurality of spacing features disposed along the first face of the growth plate that offset the first face of the growth plate from the first cell frame, which creates a cavity between the growth plate and the first cell frame. The cavity decreases when the battery cell expands.

摘要： Systems, methods, and other implementations described herein relate to a battery for use in a battery cell assembly that facilitates pack manufacturing. A method of manufacturing the battery cell assembly for the battery pack includes providing at least one battery cell in the battery cell assembly. The battery cell includes at least one prebent electrical tab. The method further includes operatively connecting a busbar to the prebent electrical tab on the battery cell, without substantially deforming the prebent electrical tab, whereby subsequent bending of the at least one prebent electrical tab is unnecessary.

摘要： A battery module having a battery cell assembly that is free from module banding is provided. The assembly includes an expandable battery cell having a first and second face, and the first face moves away from the second face as a result of the battery cell expanding. The assembly further includes a first and second cell frame. The first cell frame includes an outer peripheral extending toward the second cell frame. The second cell frame includes an outer peripheral extending away from the second face of the battery cell. Additionally, the outer peripheral of the second cell frame and the battery cell are disposed within the outer peripheral of the first cell frame with the first face facing the first frame and the second face facing the second frame.
