Does anyone know or have the capability to accurately estimate what the volumetric power density of these capacitors are (assuming they commercialize well)? In terms of replacing cell phone batteries or something, that's what matters, and I only see areal densities.
Thats the discussion. In reality, you care about both. Power density to move the energy into and out of the cell quickly to shorten charge times and supply thirsty loads. Energy density to run lower loads for longer.
