Short-circuit incidents pose a severe safety threat to lithium-ion batteries during lifetime. Understanding the underlying electrochemical behavior can help to mitigate safety risks. The electrochemically-caused rate-limiting behavior is analyzed using a quasi-isothermal test-bench, where external and local short-circuit conditions are applied to single-layered pouch cells ( 3.2 V vs Li/Li + ), which could be estimated up to 20% of the negative current collector mass.
