The entropic heat coefficient is a crucial parameter for the accurate battery electrothermal model. Despite several methods in the literature, these generally obtain significantly different results. In other words, we hardly know which one is reliable enough. I feel like it is still an open question for obtaining the accurate temperature coefficient if expensive instruments such as ARC (accelerating rate calorimeter) and DSC (differential scanning calorimeter) are not used (most research groups do not have this equipment). I have tried to extract this coefficient by pulse-rest tests at different ambient temperatures, however, it does not work well when I examine the accuracy of heat generation calculation. Does anyone give me some advice? Thanks a million.
Hello,
You ask a question that concerns all materials. To answer it, you have to go to the equation of state of solids and find the way to measure all the parameters of the elementary processes taken into account.
This is now done and in the process of being published. In a few weeks, a link to a site that brings together the means to answer your question and find its applications will be published.

Thanks for your answer and look forward to reading your work :) Claude Le Gressus
