As the world is growing very fast and the major role player is the technical sector, but when it comes to the Automotive world one cannot forget e-mobility and hence we are also contributing our part in it. We are doing an in-depth study on Solid-state batteries and Liquid state batteries and detailed comparison between them. In the end, we are also doing the thermal management of the batteries using a Simulation tool called the Simulink/Simscape Language Model. E-mobility is still in the developing phase and there are a lot of opportunities available and we targeted the Battery part. In this report we are showing with different facts, proves, calculations and experiments that how solid-state batteries (SSB) are better than currently using liquid state batteries (LSB) because experts believe that the future is of solid-state batteries because of its versatility and many advantages over LSB. We did the comparison between the current electronic vehicles using LSB(Lithium-Ion) and the future vehicles using SSB on various aspects according to our experiment, research and the result we got is outstanding and also found to be the worthy step toward the development of SSB. We also did the thermal management of the battery to increase its on-road efficiency and the result is quite satisfying as we took a small load to check the battery performance and we also gave the comparison of thermal management using two different heat transfer coefficient (5 W/m^2 K and 25 W/m^2 K) and we are able to get better cooling efficiency when we increase the value of heat transfer coefficient. Results, proposed ideas, and the research analysis clearly giving a green signal towards the speedy development of Solid-state batteries and how it overcomes the different disadvantages of Liquid state batteries, whereas Thermal Management Model proposes with several changes give us the in-depth view of the temperature rise and also by changing the heat transfer coefficient one can select a better cooling system for batteries, to operate it in an optimized range of temperature.
