“…[8][9][10][11][12] Furthermore,A ZBs also possess other advantages,including non-toxicity,low cost, and minimum requirements regarding the atmosphere. [13,14] In the last decade,most efforts are focused on enhancing battery performance (capacity delivery,c ycling stability,o rr ate property) of cathode materials in AZBs,i ncluding active materials of manganese oxides, [15][16][17] vanadate compounds, [18] Prussian blue, [19] organic cathode, [20] and so on. However,Znmetal anode is also faced with critical challenges such as dendrite growth, and side reactions including hydrogen evolution reaction (HER) and byproduct (such as an inert Zn 4 (OH) 6 SO 4 •5 H 2 Oi nZ nSO 4 aqueous electrolyte) formation (Scheme 1a), which generally lead to low coulombic efficiency,c apacity fading and short/ open circuit, thereby the commercialization of AZBs are severely hindered.…”

Aqueous zinc (Zn) batteries (AZBs) are widely considered as a promising candidate for next‐generation energy storage owing to their excellent safety features. However, the application of a Zn anode is hindered by severe dendrite formation and side reactions. Herein, an interfacial bridged organic–inorganic hybrid protection layer (Nafion‐Zn‐X) is developed by complexing inorganic Zn‐X zeolite nanoparticles with Nafion, which shifts ion transport from channel transport in Nafion to a hopping mechanism in the organic–inorganic interface. This unique organic–inorganic structure is found to effectively suppress dendrite growth and side reactions of the Zn anode. Consequently, the Zn@Nafion‐Zn‐X composite anode delivers high coulombic efficiency (ca. 97 %), deep Zn plating/stripping (10 mAh cm−2), and long cycle life (over 10 000 cycles). By tackling the intrinsic chemical/electrochemical issues, the proposed strategy provides a versatile remedy for the limited cycle life of the Zn anode.

“…Moreover, the ionic radius of Zn 2+ (0.74 Å) is smaller than that of Na + (1.02 Å) and close to that of Li + (0.69 Å) (Kundu et al, 2016;Zhang et al, 2017), making AZIBs a promising candidate for future energy storage devices. Actually, various suitable and advanced cathode materials such as MnO 2 polymorphs [e.g., α- , β- (Liu et al, 2019), γ- (Wang et al, 2020), and δ- (Nam et al, 2019)], vanadium-based oxides (Kundu et al, 2016;Soundharrajan et al, 2018), Prussian blue analogs (Zhang et al, 2015;Yang et al, 2019), and organic compounds (Guo et al, 2018;Tie et al, 2020) have been extensively explored.…”

Hybridizing δ-Type MnO2 With Lignin-Derived Porous Carbon as a Stable Cathode Material for Aqueous Zn–MnO2 Batteries

et al. 2020

With the advantages of intrinsic safety, low price, high output potential, and acceptable energy density, aqueous rechargeable Zn-MnO 2 batteries are gradually emerging as promising energy storage devices in recent years. Unfortunately, the structural instability and poor electrical conductivity of manganese dioxides still hinder their further applications. To tackle these issues, we demonstrate a high-performance cathode material for Zn-MnO 2 batteries by hybridizing lignin-derived porous carbon with δ-MnO 2 (denoted as LPC/δ-MnO 2). Benefiting from the high electrical conductivity of porous carbon, the LPC/δ-MnO 2 cathode material can offer high discharge capacity of 332.3 mAh g −1 at 0.2 A g −1 and excellent high-rate capability (196.1 mAh g −1 at 5 A g −1). Meanwhile, the assembled Zn-MnO 2 battery displays good long-term cycling stability (82% capacity retention after 1000 cycles). Such superior performances are attributed to the synergetic effect of nanostructured δ-MnO 2 and porous carbon scaffold, which is in favor of rapid Zn 2+ ion diffusion and large contribution ratio of pseudocapacitive Zn 2+ ion intercalation. The results of this study show great prospects of hybridizing biomass-derived carbon framework with electrochemically active materials toward advanced energy storage materials.

“…More recently, Tie and Niu et al [161] developed a novel aqueous ZIB based on a diquinoxalino [2,3-a:2',3'-c] phenazine (HATN) cathode in 2 M ZnSO 4 aqueous electrolyte. The charge storage of the organic cathode of these ZIBs depends on fast and reversible H + insertion/extractions, accompanied by highly reversible structural evolution.…”
