1. A battery structure, comprising:
an anode;
a cathode;
a solid electrolyte between the anode and the cathode, the solid electrolyte comprising a solid-state ionic conductive material;
a plurality of inductively heatable structures fully embedded in the solid electrolyte, wherein the plurality of inductively heatable structures are discrete from each other, wherein each inductively heatable structure comprises an inductively heatable material individually coated with an insulative layer, the insulative layer having a thickness (t) in a range of 0<t<1000 nm;
a battery packaging structure, wherein the anode, the cathode, and the solid electrolyte having the plurality of inductively heatable structures fully embedded therein are positioned within an interior of the battery packaging structure; and
an induction coil, wherein the induction coil is positioned within the interior of the battery packaging structure or is embedded within the battery packaging structure.
