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. However, the low energy densities and limited cycling stability are still major challenges for developing high‐performance ZICs. First, the energy density of ZIC is limited by the low capacitance of porous carbon cathodes. Second, aqueous electrolytes induce parasitic reactions, which results in limited voltage windows and poor cycling performances of ZICs. Third, the poor stabilities and low utilization of zinc anodes remain major challenges to develop practical ZICs. This review summarizes the recent progress in developing ZICs and highlights both the promising and challenging attributes of this emerging energy storage technology. Future research directions are proposed for developing better, lower cost, and more scalable ZICs for energy storage applications.

“…[1] Commercial supercapacitors employ an EDLC configuration which consists of two identical activated carbon (AC) electrodes using organic electrolytes. On the one hand, commercial supercapacitors have limited energy densities of 2-8 Wh kg −1 [2] compared with rechargeable batteries (40 Wh kg −1 for lead-acid batteries, [3] and 200 Wh kg −1 for new sustainable carbon precursors could further lower the production cost of porous carbon materials. [12,13] Therefore, we should focus on developing novel synthesis methods using sustainable biomass and employing low-cost chemical engineering processes.…”

Lignin, one of the renewable constituents in natural plant biomasses, holds great potential as a sustainable source of functional carbon materials. Tremendous research efforts have been made on lignin‐derived carbon electrodes for rechargeable batteries. However, lignin is considered as one of the most promising carbon precursors for the development of high‐performance, low‐cost porous carbon electrode materials for supercapacitor applications. Yet, these efforts have not been reviewed in detail in the current literature. This review, therefore, offers a basis for the utilization of lignin as a pivotal precursor for the synthesis of porous carbons for use in supercapacitor electrode applications. Lignin chemistry, the synthesis process of lignin‐derived porous carbons, and future directions for developing better porous carbon electrode materials from lignin are systematically reviewed. Technological hurdles and approaches that should be prioritized in future research are presented.

“…The need for wide utilization of renewable energies is accelerated by energy shortages and environmental pollution. To connect the unstable and intermittent electricity generated by renewable energies to the grid, it is imperative to develop energy storage technologies with high safety, low cost, and low environmental detriments. − At present, lithium-ion batteries (LIBs) are the most widely used commercial batteries; however, they suffer from limited lithium sources, flammable organic electrolytes, high explosion risk, and low environmental benignity. − Up to now, various types of energy storage technologies have been proposed and developed to substitute LIBs, such as advanced flow batteries, sodium-ion batteries, and lead–carbon batteries. − Among them, aqueous zinc-based batteries (ZBBs) are considerably promising for energy storage, because zinc has attractive features of low potential (−0.76 V vs the standard hydrogen electrode (SHE)), high theoretical capacity (820 mAh g –1 , 5855 mAh cm –3 ), environmental friendliness, and low cost. ,− At present, the most commonly investigated aqueous ZBBs include Zn-ion batteries (ZIBs, such as Zn-MnO 2 batteries and Zn-Ni batteries), Zn–air batteries (ZABs), Zn-based flow batteries (ZFBs, such as zinc–bromine (Zn-Br), zinc–iron (Zn-Fe), and zinc–iodine (Zn-I) flow batteries), and so forth. ,− …”
