Study on Thermal Characteristics of High-specific Energy Lithium-ion Batteries Based on the Simulation Modeling

Lithium-ion battery has been widely used for its advantages of large energy density coefficient, high output power and long cycle life. Simulation modeling can greatly reduce the consumption of human resources, material resources and financial resources. In this paper we focus on the electrochemical-thermal coupled model to study the behavior of regulations between the battery potential and the change of cell discharge rate. Moreover, models are set up to discuss the specific process of the temperature change inside the battery.
