The Development of a Macro Model for a 26650-Type Battery Cell

The curves for charge and discharge experiments demonstrate specific temperature and current behaviour for the 26650-type battery cell. For that reason, it is extremely important the heat impact on electrochemical reactions and on transfer actions. The base for model parameterization is built by isothermal simulations at different temperatures. In this article, there are presented modifications of thermodynamics and kinetics to accomplish a good connection with the results of the processes concerning charge and discharge curves for different C-rates and various background heat.
