Abstract
With the rapid and continuous advancement and deployment of advanced energy storage de-vices, there has been significant interest in aqueous capacitors that possess non-flammable properties and high safety features. Consequently, extensive research efforts have focused on investigating zinc anodes and low-cost carbonaceous cathode materials. Despite these efforts, the development of high-performance zinc-ion capacitors (ZICs) still faces challenges such as limited cycling stability and low energy densities. In this study, we present a novel approach to address these challenges. We demonstrate the utilization of a three-dimensionally (3D) grown conductive porous carbon framework cathode coupled with zinc anode cells, which exhibit exceptional sta-bility and durability in ZICs. Our experiments reveal a remarkable cycling performance, with a capacity retention of approximately 97.3% and a coulombic efficiency of nearly 100% even after 10,000 charge-discharge cycles. These findings signify significant progress in enhancing the performance of ZICs.
