Can someone conceptually explain the relationship between free energy G and cell potential?

When G is negative, the reaction will occur spontaneously. However, when it is positive, energy must be put in for the reaction to occur. When G is 0, the reaction is at equilibrium (this is when your battery would be dead).

Gibbs free energy is related to cell potential by the equation: ΔG°cell = −nFE°cell. If E°cell > 0, then the process is spontaneous. If E°cell < 0, then the process is nonspontaneous
