The performance and safety of lithium batteries depend heavily on every step in the manufacturing process, with tab welding being a crucial step. As the key component connecting the lithium battery's internal cell to the external circuit, tabs play a vital role in conducting current. The quality of their welding directly affects the battery's internal resistance, charge and discharge efficiency, lifespan, and even its safety.
