CHAIN-LINKED CYLINDRICAL BATTERY CELL FOR BATTERY PACKS

A chain-linked cylindrical battery cell includes a cylindrical can sealed by a top cap. The cylindrical can is configured to house a jelly-roll and electrolyte. The chain-linked cylindrical battery cell further includes a first chain ring configured to attach to an upper end of the cylindrical can, and a second chain ring configured to attach to a lower end of the cylindrical can. Each ring includes a pair of coupling rings protruding in opposite directions. Additionally, the chain-linked cylindrical can includes a chain pin configured to be inserted through the coupling rings, aligned with a longitudinal axis of the cylindrical can. The configuration allows adjacent similarly-structured chain-linked cylindrical battery cells to be rotatably connected, forming a chain-like structure suitable for battery packs.
