Current collector accounts for more than 90% of the electric conductivity and ∼90% of the mechanical strength of the electrode in lithium-ion battery (LIB). Usually, current collectors are smooth metallic thin films. In the current study, we show that if the current collector is heterogeneous, the heat generation becomes negligible when the LIB cell is subjected to mechanical abuse. The phenomenon is attributed to the guided strain concentration, which promotes the separation of the forward and the return paths of internal short circuit. As the internal impedance drastically increases, the stored electric energy cannot be dissipated as thermal energy. The modification of current collector does not affect the cycling performance of the LIB cell. This finding enables advanced thermal-runaway mitigation techniques for high-energy, large-scale energy storage systems.
