Thermal Management of Solid-State Battery

Abstract

An efficient energy storage system is crucial and the solid-state battery (SSB) is one of the prominent technologies for this. Due to its higher energy density, improved safety, and longer life cycle; SSBs are the future of energy storage. However, thermal management remains challenging as temperature could get higher due to faster charging and discharging cycles. This research explores innovative ways to improve the thermal management of batteries to reduce the overall weight of the cooling system. Solidworks is used to design the components of SSB and then ANSYS is used to examine the structural, thermal, and electrochemical properties. The batteries are assembled in prismatic and cylindrical cell designs to test innovative techniques of thermal management. Firstly, we used Phase Change Material (PCM) that helped maintain the temperature in a safe operating range and then analyzed the use of Nano-particle-like graphite in the coolant, which showed superior heat distribution. At last, the impact of micro-structure design like a grooved surface pattern is tested to increase surface area and cooling. The research demonstrates that combining PCM with coolant containing Nano-particles reduces the peak battery temperature and the grooved pattern results in further improvement of thermal stability. In conclusion, the research contributes a novel multi-faceted approach to the thermal management of SSBs, providing valuable insights into optimizing performance and safety. The result holds potential for a wide range of practical applications, paving the way for safer and more efficient energy storage technologies.Keywords: Battery Thermal Management, Solid-State Battery, Phase Change Material, Nano-particles
