The electric forces of attraction acting on the electrons on the middle plate are compensated, as the electric fields on both sides of the plate are not screened. However, it brings the system to an unstable equilibrium state. To make the system stable, we consider fast oscillations similar to those in the Kapitza pendulum. AC electric current through the middle graphene plane creates a magnetic field. In turn, the Lorentz force squeezes moving electrons towards the center of the middle plane. We present the results of numerical modeling showing the effect of AC electric current on electron movement. According to the estimates, the pseudopotential produced by the AC current may exceed 60 eV at room temperature. Such a large value of the pseudopotential is due to the high mobility and large current density in graphene. The electric field intensity between the edge plates and the middle plate may exceed the breakdown value for a conventional double-plate capacitor. It may be possible to enhance the volume electric energy density above the gasoline 34 MJ/L.
