What is the Nernst equation for a lithium ion battery?
We have used the Nernst Equation, in the chart above, to capture a lithium ion battery with a 3.7V Standard Potential. Cell Voltage matches Standard Potential when the concentration of Li+ in solution matches the concentration of Li intercalated at the anode. Here [LiC6] = [LiMxOy]. Hence [LiMxOy]/ [LiC6] = 1. Hence ln (1) = 0. Hence E = E0.
Which principle applies to a lithium-ion battery?
The same principle as in a Daniell cell, where the reactants are higher in energy than the products, 18 applies to a lithium-ion battery; the low molar Gibbs free energy of lithium in the positive electrode means that lithium is more strongly bonded there and thus lower in energy than in the anode.
