Actual materials chemist here. A PhD in physics is not that relevant to understanding the real electrochemical nuts and bolts if a battery. Just look up what a solid electrolyte interface (SEI) layer is to see how bush league current battery technology is. Compared to CMOS tech, which has benefited from trillions of dollars of R&D, batteries are in the stone age.
