Lithium-ion batteries are most preferable energy storage devices for its higher energy density, flexible form factor and lightweight design than comparable battery technologies. The present simulation work is focused on incorporating contact thermal resistance within a two-dimensional thermal model of Lithium-ion pouch cells. In the present study COMSOL Multiphysics® software has been used to model the electro-thermal behavior of Lithium-ion cell of 3.5Ah capacity has been charged/discharged at different higher charging rate (C-rate) for time of 7000 seconds. Variation of thermal contact resistance values in between active battery material sections has been done and the variation of cell temperature has been noticed. The simulation result is verified with the standard literature results.
