This work has been presented to develop a simulation model of 2D Lithium-ion Solid State Battery (SSB) for studying the thermal and electrical characteristics by varying the thickness of the electrode. This simulation model helps us to explore the cathode material characteristics to optimize lithium-ion SSB’s performance. In this paper, the simulation model has been formulated with 2D domain geometry and also encapsulated with variable parameters on a Multiphysics software. The electrochemical model was also formed with the help of mathematical modeling equations to obtain the rate capability of the li-ion SSB. This simulation model study shows the good thermal stability of the cathode material with a varied temperature range from 0⸰C to 150⸰C. Moreover, the electrical and electrochemical results also show good electrochemical reactivity, proper diffusion of li-ions, and good transport properties in the positive electrode of the li-ion SSB. Furthermore, this simulation approach shows a proper discharge curve at various C-rates and also highlights the concentration of li-ion, electrons, and heat flux with good stability in the Lithium-ion SSB.
