Hello everybody,

My name is Yogan and I am from Brazil. I am developing an article describing the mapping thermal into the cell of ZEBRA Battery.
We know that in charge process the temperature inside of the cell decrease and is necessary to use heaters to maintain at least 275ºC. On other hands, when we discharge the cell the Joule heat generated in the internal resistance during the operation increases the temperature. My simulation is based on this second case (discharge process).

The total energy produced in the cell can be specified into 4 tipo:
1. The Energy that will really be use as energy in a car, or houses.
2. The Energy that the cell will dissipate due to heat transfer process
3. The Energy (heat) the reversible heat losses, which are positive when discharging and negative when charging.
4. The energy (heat) the irreversible heating energy due to losses in the internal resistence.
Energy_Total = Energy_Useful + Energy_dissipate + Energy_from_reversible + Energy_fron_irreversible

I would like to know how can I determine the irreversible heat. For exemple, in the cell ML3-X type used in 48TL80 battery, how much Watts in produced if the discharge is 0.1C ou 0.5 C?

cheers! :D
 
I just pulled these papers from my literature collection on heat generation in Li-ion batteries.

R. Srinivasan, A.C. Baisden, B.G. Carkhuff, M.H. Butler, The five modes of heat generation in a Li-ion cell under discharge, Journal of Power Sources 262 (2014) 93-103.

This is a really good summary.
