In this study, we align these channels by epitaxiallygrowing TiO2(B) films with the assistance of an isostructuralVO(2)(B) template layer. In a liquid electrolyte, binder-freeTiO(2)(B) epitaxial electrodes exhibit a supercapacity nearthe theoretical value of 335 mA h g(-1) and an excellentcharge-discharge reproducibility for & GE;200 cycles, whichoutperform those of other TiO2(B) nanostructures. For theall-solid-state configuration employing the LiPON solid electrolyte, excellent stability persists. Our findings suggest excellent potentialfor miniaturizing all-solid-state nanobatteries in self-powered integratedcircuits.
