1. An integrated battery (IB) comprising a rechargeable secondary battery (RSB) with continuous charging from a semiconductor primary battery (SPB), wherein:
the semiconductor primary battery (SPB) comprises a plurality of pixels, each pixel comprises a micro-platform suspended by phononic MEMS nanowires from a surrounding substrate within a hermetic cavity;
one or more surfaces of the micro-platform is configured to enhance a first blackbody radiation which spontaneously cools the micro-platform continuously;
the micro-platform and nanowires form are formed within a Seebeck thermocouple powered by the temperature difference between the micro-platform and the surrounding substrate providing electric power for an external load circuit;
the nanowires are formed with phononic MEMS structure comprising phononic crystal (PnC), and/or randomly disposed scattering elements, wherein the phononic MEMS structure reduces thermal conductivity along the nanowire length;
the micro-platform and nanowires are disposed within the hermetic cavity, wherein the hermetic cavity maintains an environment within, such as a vacuum, or low thermal conductivity gas providing increased thermal isolation of the micro-platform and nanowires from the surrounding substrate;
elements of the phononic MEMS structure are physically separated by less than the mean-free-path (mfp) of at least some heat conducting phonons;
the phononic MEMS structure increases the ratio of electrical conductivity to thermal conductivity for the nanowires;
at least one of the hermetic cavity inner surfaces is exposed to the micro-platform, wherein blackbody radiation incident from the micro-platform is substantially absorbed and the at least one hermetic cavity inner surface comprises photonic absorptive structure which reduces a second blackbody radiation and reflection of the first blackbody radiation from said at least one hermetic cavity inner surface;
the plurality of SPB pixels are interconnected to form a series/parallel circuit providing a voltage level suitable for charging the rechargeable secondary battery (RSB) disposed within the integrated battery (IB); and,
the integrated battery (IB) is configured to supply power for an application load device.
