How do I determine the number of Li+ ions per formula unit of the compound, e.g. nLi+ = 4.4 for Sn, nLi+=1 for LiFePO4, nLi+ = 2 for Li3Fe2(PO4)3?

To calculate the theoretical capacity, we can use the Faraday’s law : Qtheoretical = (nF) / (3600*Mw) mAh g-1 Here, we have to know “n”.. How to know the number of Li+ ions of the electrode...
