Commercial lithium-ion battery is given by the cell notation below.
Li(s), C(graphite) || Fe(PO4)(s), LiFe(PO4)(s)
Solid-state half-reactions (assume solid-state reactions have the same reduction potentials as in solution):
Li --> Li+ + e-
Fe3+ + e- ---> Fe2+
a. What is the standard cell potential of this galvanic cell?
b. Write a balanced chemical equation (including phosphate)
c. Please calculate the ΔG° for this reaction. (Faraday’s constant) is 96,500 J/mol*V.
From the given sheet:
Li+ (aq) + e- --> Li°(s)
E°V = -3.04
Fe3+(aq) + e- ---> Fe2+ (aq)
E°V = 0.77
