| Title | Design of high-performance single-ion conducting hydrogel electrolyte for Zinc-ion batteries |
| Summary | Aqueous zinc-ion batteries (AZIBs) are considered a highly promising power supply technology due to their high energy/power density, inherent safety, and environmental friendliness. The introduction of hydrogel electrolytes has enabled the development of flexible energy storage devices. However, conventional polymer-based hydrogel electrolytes suffer from high water content and low ionic conductivity, making it difficult to effectively suppress the uncontrolled growth of Zn dendrites and side reactions at the anode, thereby limiting the rate performance and cycling stability of the battery. In this project, we aim to optimize the composition of hydrogel electrolytes to enhance their mechanical strength, promote electrolyte dissociation, and construct efficient zinc-ion migration pathways, thereby improving the ionic conductivity of the hydrogel framework and achieving high-performance zinc-ion batteries. Various characterization techniques, such as scanning electron microscopy (SEM) and a universal testing machine, will be employed to analyze the microstructure and mechanical properties of the hydrogel electrolyte. Additionally, we will assemble coin cells and systematically evaluate their electrochemical performance using an electrochemical workstation and a Bio-Logic battery testing platform, focusing on key parameters such as ionic conductivity, rate capability, and long-term cycling stability. |
