So to be clear, the three figures for charge capacity are: theoretical specific charge capacity (Ah/kg from the molar masses), theoretical charge capacity for a specific battery (Ah and based on the masses of its active ingredients), and lastly the working charge capacity derived from actual...

I have revised the calculations and page based on your feedback and this is here: Revised Calculations I was using an approach that had previously worked but translated it across incorrectly. Thanks

On second thoughts, I don't wish to bore anyone with all the details of my proposals for showing if IPC-related energy gains are from internal enthalpy or the local environment, as part of an open system, so I will just show the calculation for the charge and energy capacity of a specific...

Thank you. If I may, I will assemble my thoughts in a 1-2 page document over the next week, laying out the workable calculations. I would like to post that here, as a pdf or a link to it, and would appreciate your comments and thoughts on it. This is for preparations for a second research study...

Thanks. I have requested the full article via ResearchGate. As I understand it, the overall reaction is: LiFePO4 + 6xC ⇄ Li(1-x)FePO4 + Li(x)C6 (I haven’t used the proper subscript formatting here) but the proportion ‘x’ makes the calculations difficult. Just looking at charging, the only...

Thank you. I have only just found your reply! I got no email notice and I have posted something similar again today. When you write Li1 you mean monoatomic and non-ionic Lithium and with Li non-attached Lithium + ions?

For my battery research, I am trying to determine the reaction (Gibbs) energy for what occurs in a LiFePO4 battery as it discharges. For reference, I have used the approach that works for a Pb-Acid battery, as laid out below using molar masses, and am then trying to do the same for the LiFePO4...

In writing up a paper on some research work on the effects of transients on Lithium Iron Phosphate batteries, I am laying out the thermodynamics and energetics for the reaction laid out below, but am having trouble finding the numbers for the reaction. Does anyone know the correct figures to...

It was a personal comment from a fellow researcher. So I am not in a position to reference it. . . .

Only in part. While pulses can apparently be used to break up Sulphate deposits, I have also heard that the voltage of pulses, once they meet the battery, is effectively grounded due to the low impedance of the pulse-producing coil and the battery itself. As such they are no longer in a position...

Can inductively generated flyback pulses (~1kV) cause the decomposition or ‘consumption’ of any components in the electrolyte of a lead acid battery resulting in an energy release?
