Mechanical failure of lithium-ion batteries

The commercialization of lithium-ion batteries has accelerated the electrification process of vehicles. In the past decade, one could see great advances in the life span, cost, performance, specific energy, and specific power of batteries. At the same time, the safety of batteries has not been adequately addressed by most stakeholders in the Electric Vehicle market. The present thesis systematically investigates the deformation mechanisms of the multi-layered structure of lithium-ion battery cells subjected to various loading conditions with particular emphasis on predicting the onset of the electrical short circuit. It starts with a comprehensive testing and modeling study of all the components of the cell, including the current collectors, the separator, the pouch/shell casing, and particularly, the coatings of electrodes.
