摘要：

To enhance the electrochemical performance of the Zn solid-state battery, we introduce simonkolleite as a novel anode material. With oxygen vacancies on its surface, simonkolleite exhibits both electrical and chemical activity; these vacancies serve as n-type donors, significantly improving the material's conductivity. In this research, simonkolleite is synthesized using a straightforward and cost-effective method and employed as the anode. The all-solid-state Zn battery combines the simonkolleite anode, sodium silicate (SS) electrolyte, and graphite film (GF) cathode. Our battery configuration (simonkolleite/Ingot SS/GF) achieves a high 1280 mAh g-1 capacity and demonstrates improved cyclic stability. The large-scale module battery can also power a motor-fan unit for 1 h and 19 min.
