AI Customer ServiceDesign and fabrication of Zn ion hybrid capacitors devices. With the increasing demands for high-performance energy storage devices, aqueous zinc-ion hybrid capacitors (ZICs) attract lots of attention due to the integration of high-energy-density zinc-ion batteries (ZIBs) and high-power-density supercapacitors (SCs).
An electrochemical zinc ion capacitor (ZIC) is a hybrid supercapacitor composed of a porous carbon cathode and a zinc anode. Based on the low‐cost features of carbon and zinc metal, ZIC is a potential candidate for safe, high‐power, and low‐cost energy storage applications. ZICs have gained tremendous attention in recent years.
For instance, a zinc-ion hybrid capacitor consisting of commercial activated carbon (AC) as the cathode, metallic Zn as anodes, and Zn sulfate aqueous solution as the electrolyte was constructed by Dong et al. (Fig. 3 a).
Zinc ion hybrid capacitors (ZIHCs) are a tradeoff between zinc ion batteries (ZIBs) and SCs. Although there are many configurations, ZIHCs are mostly composed of a zinc anode, a porous carbon cathode, and Zn 2+ -ion-containing electrolytes [12, 13]. In 2016, Wang et al. constructed the first ZIHC.
3. The development of capacitor-type electrode materials for Zn-based hybrid capacitors Normally, EDLC and pseudocapacitive materials are regarded as capacitor-type electrodes of ZICs, such as activated carbon (AC), porous carbon (PC), nanostructured carbon, MXenes, transition metal oxides and conducting polymers.
The dendrites of ordinary, unmodified zinc metal after multiple deposition/dissolution of zinc ions can puncture the diaphragm and affect the safety of hybrid capacitors. Zinc metal deactivation and side reactions usually affect the stability of the device.
