Investigation of effects of design parameters on the internal short-circuit in cylindrical lithium-ion batteries

Author affiliations

Abstract

Cylindrical lithium-ion batteries are now widely applied in electric vehicles as power sources, but they still have an inevitable risk of internal short-circuit accompanied by catastrophic consequences. First, an electrochemical-thermal coupling model was established to predict the short-circuit behavior in a cylindrical battery cell with experimental validation. Second, the governing engineering design parameters such as porosity and thickness of both electrodes and separator have been parametrically discussed. In addition, the influence of the position, short-circuit area, and quantity of the short-circuit points was studied. Results show that the abovementioned governing engineering design parameters make a non-trivial difference to the cell's electrochemical behavior after a short-circuit. This may provide crucial engineering guidance for lithium-ion battery safety design.
