“…The impedance of the system increases when PEG is added to the electrolyte due to a higher charge transfer resistance on the electrode surface . The calculated zinc ion diffusion coefficients were found to be 5.635E‐11 cm 2 s −1 and 3.745E‐11 cm 2 s −1 for the control and 1 vol.% PEG200 systems, respectively . This finding is in agreement with CA results, where deposition current density decreased with the addition of PEG in the electrolyte.…”

Surface Adsorption of Polyethylene Glycol to Suppress Dendrite Formation on Zinc Anodes in Rechargeable Aqueous Batteries

Aqueous metal batteries routinely suffer from the dendritic growth at the anode, leading to significant capacity fading and ultimately, battery failure from short‐circuit. Herein, we utilize polyethylene glycol to regulate dendrite growth and improve the long‐term cycling stability of an aqueous rechargeable lithium/zinc battery. PEG200 in the electrolyte decreases the corrosion and chronoamperometric current densities of the zinc electrode up to four‐fold. Batteries with pre‐grown dendrites also perform significantly better when PEG is present in the electrolyte (41.4 mAh g−1 vs. 7.9 mAh g−1 after 1000 cycles). X‐ray diffraction and electron microscopy studies show that dendrites in the PEG‐containing electrolyte have been inhibited, leading to much smaller/smoother surface features than those of the control. The facile preparation process of the aqueous electrolyte combined with low cost and vast performance improvement in batteries of all sizes indicates high upscaling viability.

“…As a result, higher capacity can be achieved in an aqueous electrolyte, but the capacity retention is still better in an organic electrolyte. [164] As a matter of fact, a sort of harmful SEI might be formed on the electrode surface in the aqueous electrolytes too. [163] However, this might be a useful approach for ARLBs to form an artificial SEI (i.e., the same old surface coating).…”

research, aqueous electrolytes were occasionally employed for the investigation of cathode materials instead of the conventional nonaqueous electrolytes. [9,10] It was discussed that the simplicity of an aqueous electrolyte provides a better opportunity for the fundamental studies of the process of intercalation/deintercalation of Li-ions as opposed to the nonaqueous electrolytes. For instance, although the formation of solid electrolyte interphase (SEI) is of utmost importance for the cyclability of LIB, the significant role of the electrolyte does not allow to exclusively study the electrochemical behavior of the electrode material under consideration. The current research has specifically targeted the development of ARLBs, but in practice, most of the recent papers have followed the same line of research in investigating a limited range of cathode and anode materials in the same aqueous electrolytes. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] A possible reason is that the key advantage of ARLBs was low cost, and thus, the focus was limited to a few inexpensive materials (e.g., lithium salts). Aqueous electrolytes are definitely excellent choices for the fundamental studies of electrode materials, but the practical development of ARLBs needs overcoming the key obstacles rather than finding more cathode materials.In any case, aqueous electrolytes were occasionally used during the 2000s by various research groups, but there was no vivid plan for the development of ARLBs. These works have been extensively reviewed before, [29][30][31][32][33] and it is not aimed to repeat the general works on aqueous electrolytes here. During the recent years, new opportunities have been introduced, which can extend the stable potential window of aqueous electrolyte to the range of 3-4 V. Upon this advancement, aqueous electrolytes can fairly compete with the conventional nonaqueous electrolytes for the fabrication of cheaper and safer LIBs. On the other hand, novel designs such as self-healing [34] or flexible [16,35,36] ARLBs have paved the path for new practical potentials of aqueous electrolytes. The present paper specifically focuses on the recent advancements and attempts to foster the strategy of research to shed light on the pathway of this emerging area of research. Two factors are directly responsible for achieving a high energy density, the specific capacity, and the cell voltage. Since the former is not massively controlled by the electrolyte and the specific capacity of most electroactive Owing to the high voltage of lithium-ion batteries (LIBs), the dominating electrolyte is non-aqueous. The idea of an aqueous rechargeable lithium battery (ARLB) dates back to 1994, but it had attracted little attention due to the narrow stable potential window of aqueous electrolytes, which results in low energy density. However, aqueous electrolytes were employed during the 2000s for the fundamental studies of electrode materials in the absence of side reactions such as the decomposition of organic spec...

“…[40] The formation of SEI is most significant criterion in non-aqueous electrolytic cell, due to the polymerisation reaction of organic components of electrolyte on electrode surface, which facilitates the SEI development on the electrode surface. [41] In this regard, usually in aqueous electrolytic medium, the electrode surface will not undergo polymerisation with the electrolytic component. Moreover, the SEI formation usually occurs on the anode during charge/discharge process.…”

The present work focuses on a novel synthetic approach for a bis‐Indole derivative and its applications in energy storage devices. Here, an aqueous rechargeable lithium ion battery (ARLIB) with organic active material electrodes of inexpensive and sustainable, bis‐indole derivative called 2‐[1H‐indol‐2‐yl(1H‐indol‐3‐yl)methyl]phenol (b‐IMP) and Lithiated quinizarin (Li‐QZ) are used as cathode and anode respectively in saturated Li2SO4supporting electrolyte. The electrochemical activities of these organic redox active materials are studied using cyclic voltammetry, galvanostatic charge potential limit and potentiostatic electrochemical impedance spectroscopy methods. The cell b‐IMP | Sat. Li2SO4 | Li‐QZ has delivered an exceptionally better cell‐voltage of 0.7 V with a discharge capacity of 292 mA h g−1 with 92% columbic efficiency even after 300 cycles. The cell comprises of b‐IMP and Li‐QZ as cathode and anode materials respectively, which exhibits remarkable cyclizability with good discharge capacity and thus signifies a major advance in organic ARLIBs.
