The maximum capacitive energy stored in polymeric dielectric capacitors, which are ubiquitous in high-power-density devices, is dictated by the dielectric breakdown strength of the dielectric polymer. The fundamental mechanisms of the dielectric breakdown, however, remain unclear. Based on a simple free-volume model of the polymer fluid state, we
We present a theoretical analysis of charge storage in electrochemical capacitors with electrodes based on carbon nanotubes. Using exact analytical solutions supported by Monte Carlo simulations, we show how the limitations of the electron density of states in such low-dimensional electrode materials may help boost the energy stored at increased voltages.

The electric displacement is D ∝ ε, where ε is the permittivity. The maximum energy stored in the dielectric material is dictated by the maximum electric field that the material can withstand and is termed the dielectric strength (E BD) of the material.Thus, to increase the maximum energy density of the materials, both ε and E BD need to be increased. 3,4 Polymer
