Before Generally $K>1$ and so energy density in dielectric is higher than that in vacuum for the same amount of field intensity. ie: starting with the expression for the increment of electrostatic energy in term of the increment of free charge. It's corrected, thanks!! This composite exhibits a stable high dielectric permittivity and low dielectric loss over a wide frequency range, in addition to a large energy density. For linear dielectrics, the energy density ( Ue) equation is described as follows: (Equation 1) U e = 0.5 0 r E b 2 where 0 is the vacuum dielectric constant, r is the relative dielectric constant and Eb is the breakdown strength.

However, if we are holding $Q$ constant then we really should be using the equation $U=\frac12\frac{Q^2}{C}$ which then predicts a decrease in energy as $C$ increases. Copyright [2022] Elsevier.
