Zwitterionic Sulfobetaine Hydrogel Electrolyte Building Separated Positive/Negative Ion Migration Channels for Aqueous Zn‐MnO₂ Batteries with Superior Rate Capabilities

Advanced Energy Materials (2021)

Funian Mo Ze Chen Guojin Liang Donghong Wang Yuwei Zhao

In the originally published manuscript an incorrect 1 H-NMR spectra of the [2-(Methacryloyloxy)ethyl]diethy-(3-sulopropyl) (MAEDS) monomer in Figure 1b and its magnified figure (Figure S1a) was presented.Two independent testing agencies have retested the 1 H-NMR of MAEDS, and the correct spectra including the carefully modified signal assignments is shown in the corrected Figure 1 and Figure S1a on pages 2 and 3 respectively.The references to extraction of the chemicals from celery and Beta vulgaris L. have also been removed from the new Figure 1.The monomer of cellulose nanofibrils was bought from "Tianjin Woodelf Biotechnology Co., Ltd."The MAEDS was bought from Aladdin.In addition the specific sulfobetaine used in the work has not been found in natural plants.Therefore, the claim that "all monomers are natural" was incorrect.

Guojin Liang Haibo Hu Lei Liao Yunbin He Changhui Ye

Highly flexible and bright alternating current electroluminescent devices are designed and fabricated with a top emission structure and Ag nanowires serving as both top and bottom electrodes. The devices exhibit simultaneously high luminance (957 cd m−2 @ 195 V and 2 kHz), and unprecedented flexibility as well as mechanical stability, being able to endure a strain as large as 6.5% and to maintain 88.4% luminance after 1000 bending-recovery cycles.

A Flexible Solid‐State Aqueous Zinc Hybrid Battery with Flat and High‐Voltage Discharge Plateau

Advanced Energy Materials (2019)

Zhuoxin Liu Qi Yang Donghong Wang Guojin Liang Youhuan Zhu

Abstract The migration of zinc‐ion batteries from alkaline electrolyte to neutral or mild acidic electrolyte promotes research into their flexible applications. However, discharge voltage of many reported zinc‐ion batteries is far from satisfactory. On one hand, the battery voltage is substantially restricted by the narrow voltage window of aqueous electrolytes. On the other hand, many batteries yield a low‐voltage discharge plateau or show no plateau but capacitor‐like sloping discharge profiles. This impacts the battery's practicability for flexible electronics where stable and consistent high energy is needed. Herein, an aqueous zinc hybrid battery based on a highly concentrated dual‐ion electrolyte and a hierarchically structured lithium‐ion‐intercalative LiVPO 4 F cathode is developed. This hybrid battery delivers a flat and high‐voltage discharge plateau of nearly 1.9 V, ranking among the highest reported values for all aqueous zinc‐based batteries. The resultant high energy density of 235.6 Wh kg −1 at a power density of 320.8 W kg −1 also outperforms most reported zinc‐based batteries. A designed solid‐state and long‐lasting hydrogel electrolyte is subsequently applied in the fabrication of a flexible battery, which can be integrated into various flexible devices as powerful energy supply. The idea of designing such a hybrid battery offers a new strategy for developing high‐voltage and high‐energy aqueous energy storage systems.

Inhibiting Grain Pulverization and Sulfur Dissolution of Bismuth Sulfide by Ionic Liquid Enhanced Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) for High-Performance Zinc-Ion Batteries

ACS Nano (2019)

Yuwei Zhao Longtao Ma Yongbin Zhu Peng Qin Hongfei Li

Aqueous zinc-ion batteries (ZIBs) possess energy storages advantages, including low cost, high safety, and durable lifetimes. Materials are worth exploring to achieve high-performance batteries. Although Bi2S3 is predicted to be highly capable for energy storage, it has never been used in aqueous ZIBs due to the structure degradation. Herein, we apply Bi2S3 in aqueous ZIBs and develop an ionic liquid enhanced poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) coating to perfectly stabilize the Bi2S3 electrode, which plays three roles of providing high conductivity, inhibiting grain pulverization and sulfur dissolution, and acting as an artificial solid electrolyte interphase. The synergistic merits of the desirable capacity of Bi2S3 and a versatile polymer provide a capacity of 275 mAh g-1 and excellent cycling stability up to 5300 cycles with 95.3% retention. A reversible conversion mechanism into hexagonal ZnS is revealed by investigation of a variety of spectra. The prepared quasi-solid battery based on a high concentration salt electrolyte/polyacrylamide hydrogel exhibits a high energy density (315 Wh kg-1) and long-term cyclability over 5300 cycles. For demonstration, a single battery can power a digital hygrometer thermometer for more than 14 h 48 min. This work highlights a ground-breaking demonstration of incorporating structural integrity with stable interfacial chemistry.

Starch-mediated colloidal chemistry for highly reversible zinc-based polyiodide redox flow batteries

Nature Communications (2024)

Zhiquan Wei Zhaodong Huang Guojin Liang Yiqiao Wang Shixun Wang

Aqueous Zn-I flow batteries utilizing low-cost porous membranes are promising candidates for high-power-density large-scale energy storage. However, capacity loss and low Coulombic efficiency resulting from polyiodide cross-over hinder the grid-level battery performance. Here, we develop colloidal chemistry for iodine-starch catholytes, endowing enlarged-sized active materials by strong chemisorption-induced colloidal aggregation. The size-sieving effect effectively suppresses polyiodide cross-over, enabling the utilization of porous membranes with high ionic conductivity. The developed flow battery achieves a high-power density of 42 mW cm

Spider Silk‐Inspired Binder Design for Flexible Lithium‐Ion Battery with High Durability

Advanced Materials (2023)

Yanbo Wang Jiaxiong Zhu Ao Chen Xun Guo Huilin Cui

The development of flexible lithium-ion batteries (LIBs) imposes demands on energy density and high mechanical durability simultaneously. Due to the limited deformability of electrodes, as well as the flat and smooth surface of the metal current collectors, stable/durable/reliable contact between electrode materials and the current collectors remains a challenge, in particular, for electrodes with high loading mass and heavily deformed batteries. Binders play an essential role in binding particles of electrode materials and adhering them to current collectors. Herein, inspired by spider silk, a binder for flexible LIBs is developed, which equips a cross-linked supramolecular poly(urethane-urea) to the polyacrylic acid. The binder imparts super high elastic restorability originating from the meticulously engineered hydrogen-bonding segments as well as extraordinary adhesion. The developed binder provides excellent flexibility and intact electrode morphologies without disintegration even when the electrode is largely deformed, enabling a stable cycling and voltage output even when the batteries are put under tough dynamic deformation tests. The flexible LIBs exhibit a high energy density of 420 Wh L-1 , which is remarkably higher than reported numbers. The unique binder design is greatly promising and offers a valuable material solution for LIBs with high-loading mass and flexible designs.

Conversion‐Type Nonmetal Elemental Tellurium Anode with High Utilization for Mild/Alkaline Zinc Batteries

Advanced Materials (2021)

Ze Chen Chuan Li Qi Yang Donghong Wang Xinliang Li

Zinc ion batteries (ZIBs), generally established on an excessive metallic Zn anode and aqueous electrolytes, suffer from severe dendrites and gassing issues at Zn side, resulting in poor cycling life. Substituting Zn metal anode with non-Zn ones is a promising strategy for solving these problems, whereas this is still restricted by the limited anode alternatives. Herein, by replacing metal Zn with chalcogen element tellurium (Te), a conversion-type Te-based ZIB is reported that can work in both mild and alkaline electrolytes. As expected, the as-assembled mild Te/MnO2 and alkaline Te/Ni(OH)2 cells deliver remarkable capacities up to 106 and 161 mAh g-1anode+cathode , respectively, with a high utilization of anode (50.1% for the Te/MnO2 and 38.9% for the Te/Ni(OH)2 ), which surpass all ZIBs. Ultralong cycling life (over 75% capacity retention after 5000 cycles) is achieved in the two systems, benefiting from the stable conversion mechanisms (mild: Te to ZnTe2 to ZnTe; alkaline: ZnTe to Te to TeO2 ) with thoroughly eliminated dendrites and gassing. Moreover, high gravimetric energy density of ZIBs is also achieved, which are 176.3 Wh kg-1anode+cathdoe (Te/Ni(OH)2 ) and 81 Wh Kg-1anode+cathode (Te/MnO2 ), respectively. This work sheds light on the development of advanced conversion-type anode for high-performance batteries with superior stability.
