Measuring the Internal Short Circuit Resistance Under Mechanical Abusive Conditions
Abstract
Li-ion battery safety has been a focus of the automotive industry and energy storage markets. Most of researches on Li-ion batteries under mechanical abusive conditions are concerned with the evolution of mechanical damage process inside the jellyroll. However, the Li-ion battery’s initiation of thermal runaway is the most concerned safety issue. No matter the electrochemical model or the equivalent circuit model, internal short circuit resistance is the key parameter. Determination of its value is very complicated by several parameters, including the intrinsic resistance and the contact resistance. It is also very difficult to measure the value directly. In this study, the self-discharge current is utilized to calculate the internal short circuit resistance.
