In electrochemistry, the quantity in which we are most interested is E, the potential energy of the system. It is the value you see on a new E = 1.5V or E = 6 V battery. We can relate this idea of work done in electrochemistry to the thermodynamic concept of work, free energy, through the equation: free energy = ∆ G = -q E = - nFE
