What is it about?
This chapter discusses how to measure the heat flux of lithium-ion battery cells for different applications such as electric vehicles and smart grids using a calorimeter. The calorimeter can help determine the efficiency parameter of the battery cell by considering the heat loss and hysteresis effects. The chapter also proposes a new method for calculating the efficiency parameter that is more accurate and comparable. The chapter shows how the calorimetric experiments can help predict the temperature distribution of a battery cell and a cell array.

Perspectives
Isothermal Calorimeter can accurately measure the heat generation and efficiency of lithium-ion battery cells for various applications such as electric vehicles or smart grids, which can help improve their design, optimization, and performance evaluation. An efficient parameter based on isothermal calorimetry measurements can enable more effective comparison between different types of batteries. Thermal sensitivity factors that influence the performance of energy storage systems (such as current rate and temperature requirements) can be understood and modeled to predict their impact on the system behavior. Calorimeter experiments that can predict the temperature distribution of a single battery cell and an array of cells can help understand the internal working conditions and develop safer designs.
