    Usually supercapacitor electrodes are made of homogenous materials such as carbon. What if we make them out of heterogenous materials with large electron work function difference between two electrodes materials? Doesn't it mean that we will need to spend extra energy to transfer electrons from an electrode with lower work function to electrode with higher work function and therefore store more energy in this way?
