Batteries with high theoretical energy densities

As expected, (CF) n /Li battery has a high practical energy density (>2000 Wh kg −1, based on the cathode mass) for low rates of discharge (<C/10) [63]. However, it is found that the power density of (CF) n /Li battery is low due to kinetic limitations associated with the poor electrical conductivity of (CF) n of strong covalency [64].
