The new generation battery which can harvest energy from sunlight and chemically store energy that make energy storage and transportation more flexible, are of great significance for energy recycling and society sustainable development.We design and synthesize novel transition metal oxide nitride by situ self-assembly and hydrothermal/solvothermal process, which were used as counter electrode (CE) in dye-sensitized solar cells (DSSC) and anode materials of Li-ion battery (LIB), respectively,assembling into an integrated power pack of DSSC and LIB via a back-to-back pattern.The effects of synthesis conditions, surface morphologies, surface composition, grain size,crystalline defects, doping levels and electronic structure on the electrochemical performance of these hybrid materials in an integrated power pack were systematically investigated.We explore a new technical route to realize the morphology-controllable preparation and the optimized performance of low-cost hybrid materials used in the integrated devices, which will promote the rapid development of new concept integrated devices that coupling energy harvesting, energy conversion and energy storage techniques.
