Investigation of thermal management capacity of Casson electrolytes in porous electrodes in lithium-ion battery applications

The study of the Casson electrolyte in lithium-ion batteries (LIBs) is important because of their complexities due to tougher operational conditions and other challenges during charging–discharging challenges with their improved thermal management capacity and enhanced safety. This further optimizes the thermal management avoiding chances of hot spots or thermal runaway, thereby making LIBs safer. In this investigation, convective loads for non-Newtonian fluid as electrolyte Casson-type boundary layer flow related to plate and flat surfaces in non-Darcy permeable porous electrodes have been deliberated. We have employed the Optimal Homopotic Asymptotic Method technique to solve the equation of the system. The effects and influences of Casson factors, permeability, flow constraints, Prandtl values related to flow and thermal dissipation, and boundary layer profiles have been studied. From the results, it is concluded that thermal parameters and porousness have affected the system, and the upsurge in the porousness actually decreases heat transport effects and proportions. The results of this study are relevant to the development of more effective porous electrodes for achieving high performance with long cycle life. These studies help improve the utilization of mass and heat transfer properties, as affected by the non-Newtonian behavior of the electrolyte, to help in the design of next-generation LIBs with higher energy density along with fast charge/discharge rates.
