PaulTherm Posted November 20, 2015 Share Posted November 20, 2015 Hey guys, How can one calculate the energy density of a LiFePO4 battery cell? Is there any way to evaluate this number precisely if one knows the amount of Lithium in each electrode? This number represents the maximum amount of energy that can be used for charging/discharging but also for other chemical reactions inside the cell or is it only the electric energy? I appreciate any answer! Paul Link to comment Share on other sites More sharing options...
Lagoon Island Pearls Posted November 20, 2015 Share Posted November 20, 2015 I think what you are looking for is the ability to calculate coulombs.https://en.wikipedia.org/wiki/Coulomb Link to comment Share on other sites More sharing options...
DevilSolution Posted November 21, 2015 Share Posted November 21, 2015 (edited) The rate of discharge will effect the batteries health, so unless you can measure the exact rate of discharge you can only roughly estimate, [math]t = h (\frac{C}{IH})^k [/math] Yeh there is other chemical reactions, namely the ionic charge from anode to cathode and the disintegration of the anode with chemical build up slowly stopping the flow of electrons.

MNFsoft Posted March 17, 2018 Share Posted March 17, 2018 you can watch this video on youtube @ about 39 minute it explains a lot! Link to comment Share on other sites More sharing options...
