【 摘 要 】

tsThis work is a new guide for the design of on-chip energy integrated systems toward the goal of developing highly safe, economic, and long-life smart wearable electronics.The biomass kelp-carbon based on unique 3D micro-/nanostructure combined with multivalent ion storage contributes to high capacity of the Zn-ion hybrid capacitor.The flexible solar-charging self-powered system with printed Zn-ion hybrid micro-capacitor as energy storage module exhibits fast photoelectric conversion/storage rate, good mechanical robustness, and cyclic stability.
