“…The resulting petals have a thickness of around hundreds of nm that can reach the formation of two-dimensional nanosheets. Compared with the previous results, 36,39 the zinc nanosheets are more sparsely distributed due to the interaction of fatty alcohols in the plating process and the isolation of zinc ions. Besides, during the operation of the Zn-ion hybrid supercapacitor, it is possible for the zinc electrode to undergo a chemical reaction that causes the formation of dendrites:Zn + 4OH − ↔ Zn(OH) 4 2− + 2e − ↔ ZnO + 2OH − + H 2 O + 2e − .…”

“…First, the MCS–PANi composite (cathode) was directly grown on a graphite paper substrate by the electrodeposition to form a porous structure as reported previously. 39 Meanwhile, a metallic Zn-based electrode (anode) was prepared by the electroplating method using a mixture of fatty alcohol ethoxylate and ZnSO 4 solution as the electrolyte, resulting in the formation of a hierarchical micro-flower-like Zn structure. Subsequently, an MPZHSC was assembled by the MCS–PANi composite cathode, Zn anode, ZnSO 4 /MnSO 4 electrolyte and nonwoven PP separator as shown in Scheme 1.…”

“…In the current work, the sweep potential is up to 2 V. This potential window value is relatively high compared to those in previous studies on Zn-ion hybrid supercapacitors as well as aqueous Zn-ion batteries. 23–28,31–35,39 This will increase the energy storage capacity of the supercapacitor as the energy is proportional to the square of the potential.

“…The high specific capacitances of the single electrode and the full-cell supercapacitor obtained indicate the high energy reserve of the MCS–PANi electrode material, and it is better than that of the recently published articles. 39,60,61 The working mechanism of the full-cell MPZHSC can be explained based on the reaction equations of (1)–(6). Here, OH − ions are the main factor for the operation process.…”

Zinc‐ion hybrid supercapacitors (ZHSCs) may be the most promising energy storage device alternatives for portable and large‐scale electronic devices in the future, as they combine the benefits of both supercapacitors and zinc‐ion batteries. Even though many surprise outcomes have been accomplished with ZHSCs, the creation of suitable cathode materials and electrolytes, as well as the enhancement of zinc anodes, continue to be the most difficult obstacles in the development of high‐performance ZHSCs. The low capacitance of the cathode material, poor stability, and low utilization rate of the zinc anode seriously affect the electrochemical performance and application of ZHSCs. Furthermore, parasitic processes in aqueous electrolytes, such as the hydrogen and oxygen evolution reactions might result in low‐voltage windows and unsatisfied cycling performance of the ZHSCs. This review provides a concise summary of the most recent developments and energy storage mechanisms in ZHSCs. Meanwhile, the cathode material design strategy (structural engineering, hybrid‐composite design, heteroatom doping, and so on), the zinc anode design strategy (zinc foil improvement, zinc‐free metal composites, and so on), and the structure–activity relationship of the electrochemical performance of ZHSCs are discussed. Additionally, a summary of the impact of modifications in electrolyte composition on the electrochemical performance of ZHSCs is provided. Finally, this review also discusses the future development direction of ZHSCs. It is anticipated that this evaluation will serve as a helpful reference for the creation of high‐performance ZHSCs, which will hasten the development of these devices.

The global pandemic of coronavirus has caused a huge blow to the whole human society. [1] In this regard, the development of renewable energy and corresponding energy Constructing ionic conductive hydrogels with diversified properties is crucial for portable zinc-ion hybrid supercapacitors (ZHSCs). Herein, a freezetolerant hydrogel electrolyte (AF PVA-CMC/Zn(CF 3 SO 3 ) 2 ) is developed by forming a semi-interpenetrating anti-freezing polyvinyl alcohol-carboxymethyl cellulose (AF PVA-CMC) network filled with the ethylene glycol (EG)containing Zn(CF 3 SO 3 ) 2 aqueous solution. The semi-interpenetrating AF PVA-CMC/Zn(CF 3 SO 3 ) 2 possesses enhanced mechanical properties, realizes the uniform zinc deposition, and impedes the dendrite growth. Notably, the interaction between PVA and EG suppresses the ice crystal formation and prevents freezing at −20 °C. Due to these advantages, the designed hydrogel owns high ionic conductivity of 1.73/0.75 S m −1 at 20/−20 °C with excellent tensile/compression strength at 20 °C. Impressively, the flexible AF quasi-solid-state ZHSC employing the hydrogel electrolyte achieves a superior energy density at 20/−20 °C (87.9/60.7 Wh kg −1 ). It maintains nearly 84.8% of the initial capacity after 10 000 cycles and a low self-discharge rate (1.77 mV h −1 ) at 20 °C, together with great tolerance to corrosion. Moreover, this device demonstrates a stable electrochemical performance at −20 °C under deformation. The obtained results provide valuable insights for constructing durable hydrogel electrolytes in cold environments.
