Abstract

Dielectric compositions that include compound of the formula [(M′)1−x(A′)x][(M″)1−y−z,(B″)y(C″)z]O3−δ(VO)δ and protonated dielectric compositions that include a protonated dielectric compound within the formula [(M′)1−x(A′)x](M″)1−y−z(B″)y(C″)z]O3−δ+h(Vo)δ(H•)2h are disclosed. Composite materials that employ one or more of these dielectric compounds together with an electrolyte also are disclosed. Composite material that employs one or more of these dielectric compounds together with an electrochemally active material also are disclosed.
