Comparative Performance Analysis of Different Cathode materials of Solid State Lithium ion Battery

Abstract

In this paper , a single dimensional solid state lithium(Li)-ion batteries are simulated at different C-rates to analyze the characteristics like discharge curves, electrolyte potential along the thickness of electrolyte and variation of concentration along the electrolyte and positive electrode by using multi-physics simulation software tool, COMSOL. Li-ion batteries can be designed with different cathode materials but every material has its own advantages and disadvantages along with their applications. So, the main focus of this paper is to compare the characteristics of different cathode materials of Li-ion battery at different C-rates with similar design operating parameters.
