Abstract

A structural capacitor includes at least one pair of electrodes comprising a positive electrode and a negative electrode, with a body of dielectric material disposed therebetween. The combination of the electrodes and dielectric has a stiffness which can be between 10 1000 GPa, and in some instances between 50 MPa-100 GPa. Failure strength of the combination can be between 1 MPa-10 GPa, and in specific instances between 10 MPa-1 GPa. The capacitor may include a plurality of electrode pairs. The dielectric may include a reinforcing material therein, and the capacitors may be configured in a variety of shapes so as to function as structural elements for articles of construction.
