Abstract: A CURRENT COLLECTOR LID FOR A CYLINDRICAL BATTERY CELL The disclosure herein relates to a current collector lid (200) for a cylindrical battery cell (100) with an enhanced venting mechanism. The current collector lid (200) includes a first portion (202) connected to electrode tabs, a second portion (204) positioned concentrically inwards of the first portion, a plurality of reinforcement members (206) integrated with the second portion, and a structurally weakened venting portion (208) connecting the two portions. The reinforced second portion resists self-expansion under internal pressure of the cell, leading to increased stress concentration at the venting portion, which facilitates controlled rupturing and gas venting at a predetermined threshold pressure. The current collector lid (200) provides enhanced safety through reliable venting at a lower pressure without requiring a reduction in the venting portion's thickness, improved resistance to deformation, and optimized reinforcement distribution.
