Thermal component for an electrochemical lithium-ion battery model: impact and variation on the battery performance

Different battery chemistry gives different characteristics; however, these differences are gauged by the battery temperature through the Arrhenius law. A battery model is essential to predict and acts as a tool for analyzing the performance of a battery in the design stage, particularly for a batte...
