Claim of US Patent No. 10,143,081

1. A stretchable battery, comprising:a stretchable substrate including an elastic and electrically insulative material structured to conform to an outer surface of an object;
a current conductor layer attached to the stretchable substrate, wherein the current conductor layer includes a first elastic composite material comprising a first electrical conductor and a multi-block copolymer configured to form a first hyperelastic binder that creates contacts between particles of the first electrical conductor within a network formed by the multi-block copolymer;
an anode attached to the current conductor layer and arranged over the stretchable substrate, wherein the anode includes a second elastic composite material comprising a second electrical conductor and the multi-block copolymer configured to form a second hyperelastic binder that creates contacts between particles of the second electrical conductor within a network formed by the multi-block copolymer; and
a cathode arranged over the stretchable substrate, wherein the cathode includes a third elastic composite material comprising a third electrical conductor and the multi-block copolymer configured to form a third hyperelastic binder that creates contacts between particles of the third electrical conductor within a network formed by the multi-block copolymer,
wherein the stretchable battery is operable to store energy while undergoing stretching.
