A Semisolid Electrolyte for Flexible Zn-Ion Batteries

ACS Applied Energy Materials (2019)

Yanying Lu Tianyu Zhu Nansheng Xu Kevin Huang

Mechanically strong, ionically conductive, and operationally safe electrolytes are of paramount importance to flexible and wearable electronics. Herein, we report a three-dimensional, double-cross-linked gelatin and sodium alginate hydrogel imbibed with ZnSO4 aqueous solution as an electrolyte membrane for flexible Zn-ion batteries. We show that the designed polymer electrolyte membrane exhibits superior properties in ionic conductivity, mechanical flexibility, electrochemical stability, and compatibility with the Zn anode. The resultant Zn-ion battery outperforms the baseline liquid counterpart in capacity, rate capability, and cycle stability, making it a promising electrolyte membrane candidate for flexible batteries for wearable electronics.

An Alternative to Lithium Metal Anodes: Non‐dendritic and Highly Reversible Sodium Metal Anodes for Li–Na Hybrid Batteries

Angewandte Chemie (2018)

Qiu Zhang Yanying Lu Licheng Miao Qing Zhao Kexin Xia

Abstract Highly reversible, stable, and non‐dendritic metal anode (Li, Na etc.) is a crucial requirement for next‐generation high‐energy batteries. Herein, we have built a Li–Na hybrid battery (LNHB) based on Na plating/stripping, which features a high and stable coulombic efficiency of 99.2 % after 100 cycles, low voltage hysteresis (42 mV at 2 mA cm −2 ), and fast charge transfer. As a result of the Li + electrostatic shield layer, the Na deposition showed cubic morphology rather than dendritic, even at high current density of 5 mA cm −2 . The solvation/desolvation of Li + and Na + were modelled by density functional theory calculations, demonstrating the fast desolvation kinetics of Na + . Owing to the superior performance of the Na metal anode, the LNHB coupled with LiFePO 4 cathode exhibited low voltage hysteresis and stable cycling performance that demonstrates its feasibility in practical applications.

Metallopolymer as a Solid Electrolyte for Rechargeable Zn-Metal Alkaline Batteries

ACS Materials Letters (2021)

Tianyu Zhu Yanying Lu Kevin Huang Chuanbing Tang

Solid-electrolyte-based rechargeable metal-ion batteries hold great promise as low-cost, flexible, and high-safety energy storage devices. Zn-metal alkaline batteries, developed for more than a century, have dominated the market of primary batteries, but remain nonchargeable, because of serious side reactions and irreversible anodic reactions. A key component involved in these unfavorable reactions is the alkaline electrolyte. Here, we report a solid metallopolymer electrolyte (SME) with low alkaline solution uptake, high mechanical strength, exceptional stability, and excellent ion conductivity for rechargeable Zn-metal alkaline batteries. Compared to alkaline cells based on liquid and hydrogel electrolytes, SME-based Zn-metal alkaline batteries show dramatically enhanced cycling performance under harsh testing conditions by suppressing the electrolyte depletion and anode passivation.

Redox-Reversible Electrode Material for Direct Hydrocarbon Solid Oxide Fuel Cells

ACS Applied Materials & Interfaces (2020)

Peng Qiu Xin Yang Wanhua Wang Tong Wei Yanying Lu

Solid oxide fuel cells (SOFCs) can directly operate on hydrocarbon fuels such as natural gas; however, the widely used nickel-based anodes face grand challenges such as coking, sulfur poisoning, and redox instability. We report a novel double perovskite oxide Sr2Co0.4Fe1.2Mo0.4O6-δ (SCFM) that possesses excellent redox reversibility and can be used as both the cathode and the anode. When heat-treated at 900 °C in a reducing environment, double perovskite phase SCFM transforms into a composite of the Ruddlesden-Popper structured oxide Sr3Co0.1Fe1.3Mo0.6O7-δ (RP-SCFM) with the Co-Fe alloy nanoparticles homogeneously distributed on the surface of RP-SCFM. At 900 °C in an oxidizing atmosphere, the composite transforms back into the double perovskite phase SCFM. The excellent oxygen reduction reaction catalytic activity and mixed ionic-electronic conductivity make SCFM an excellent cathode material for SOFCs. When SCFM is used as the anode, excellent performance and stability are achieved upon either direct oxidation of methane as a fuel or operation with sulfur-containing fuels. The excellent redox reversibility coupled with outstanding electrical and catalytic properties manifested by SCFM will enable a broad application in energy conversion applications.

Stable Na plating/stripping electrochemistry realized by a 3D Cu current collector with thin nanowires

Chemical Communications (2017)

Yanying Lu Qiu Zhang Mo Han Jun Chen

Current collectors have a significant role in Na plating and stripping. Here we demonstrate that a three-dimensional (3D) Cu current collector with thin nanowires (<40 nm) can significantly promote the electrochemical deposition stability of Na via tuning a Na metal plating model, therefore contributing to a high efficiency, long lifespan, and low overpotential during electrode/battery cycling.
