Transport in Thin Layer Batteries

The need for smaller, more powerful, higher capacity batteries is ever increasing. This has resulted in the development of ultra-thin (ca. 10 nm) batteries in which the anode and cathode are separated by an ultra-thin electrolyte layer. At this length scale electrical double layers, that form at the electrodes (both the anode and cathode), begin to overlap and result in changes to the molecular transport of Li ions. We investigate this phenomenon theoretically using finite element simulations and experimentally using ultra-thin electrochemical cells.
