Disodium Malate Electrolyte Additive Facilitates Dendrite-Free Zinc Anode: Deposition Kinetics and Interface Regulation.

Due to the presence of HO within the solvated sheath of [Zn(HO)] as well as reactive free water in the electrolyte bulk phase, the extended cycling of aqueous zinc-ion batteries (AZIBs) is significantly affected by detrimental side reactions and the growth of Zn dendrites. This study significantly enhances the long-term cycling stability of AZIBs by introducing a small amount of disodium malate (DM) into a 2 m ZnSO electrolyte solution. DM involvement in the solvation sheath of Zn reduces the desolvation energy of Zn, thereby mitigating the corrosion and hydrogen evolution reaction (HER) of the negative electrode surface by [Zn(HO)] ions.

Designing hard carbon microsphere structure via halogenation amination and oxidative polymerization reactions for sodium ion insertion mechanism investigation.

Hard carbon as a negative electrode material for sodium-ion batteries (SIBs) has great commercial potential and has been widely studied. The sodium-ion intercalation in graphite domains and the filling of closed pores in the low voltage platform region still remain a subject of controversy. We have successfully constructed hard carbon materials with a pseudo-graphitic structure by using polymerizable p-phenylenediamine and dichloromethane as carbon sources.

Two-dimensional layered lithium lanthanum titanium oxide/graphene-like composites as electrodes for lithium-ion batteries.

Perovskite-structured (ABO) lithium lanthanum titanate (LiLaTiO, LLTO) is widely used in all solid state lithium ion batteries due to its high ionic conductivity. In this study, a two-dimensional LLTO nanosheet/graphene (LLTO/C) nanosheet composite has been designed as an electrode material for lithium-ion batteries (LIBs). LLTO/C not only exhibits the ionic conductivity properties of perovskite-type LLTO, but the graphene between the layers of LLTO nanosheets also endows the material with additional electronic conductivity.

Tuning the Defects of Two-Dimensional Layered Carbon/TiO Superlattice Composite for a Fast Lithium-Ion Storage.

Defect engineering is one of the effective ways to improve the electrochemical property of electrode materials for lithium-ion batteries (LIB). Herein, an organic functional molecule of p-phenylenediamine is embedded into two-dimensional (2D) layered TiO as the electrode for LIB. Then, the 2D carbon/TiO composites with the tuning defects are prepared by precise control of the polymerization and carbothermal atmospheres.

Rapid Electrochemical Activation of V O @C Cathode for High-Performance Zinc-Ion Batteries in Water-in-Salt Electrolyte.

Aqueous Zn-ion batteries (ZIBs), with the advantages of low cost, high safety, and high capacity, have great potential for application in grid energy storage and wearable flexible devices. However, their commercial application is still restricted by their inferior long-term cycling stability, Zn dendrite formation, and the decomposition of aqueous electrolyte. In this study, a Zn|Zn(CF SO ) +LiTFSI|V O @C cell is constructed to address the above issues.

Nanocellulose Based Filtration Membrane in Industrial Waste Water Treatment: A Review.

In the field of industrial wastewater treatment, membrane separation technology, as an emerging separation technology, compared with traditional separation technology such as precipitation, adsorption, and ion exchange, has advantages in separation efficiency, low energy consumption, low cost, simple operation, and no secondary pollution. The application has been expanding in recent years, but membrane fouling and other problems have seriously restricted the development of membrane technology. Natural cellulose is one of the most abundant resources in nature.

Controllable growth of carbon nanosheets in the montmorillonite interlayers for high-rate and stable anode in lithium ion battery.

A novel insertable and pseudocapacitive Li ion material for highly ordered layered montmorillonite/carbon is explored in the present study. The commercially available protonated montmorillonite and 3,3'-diaminobenzidine act as starting materials to synthesize the layered material via hydrothermal intercalation, oxidative polymerization and carbonization. This method of preparing montmorillonite/carbon nanocomposite exhibits several advantages.

Intercalation of Carbon Nanosheet into Layered TiO Grain for Highly Interfacial Lithium Storage.

Interfacial energy storage contributes a new mechanism to the emergence of energy storage devices with not only a high-energy density of batteries but also a high-power density of capacitors. In this study, success was achieved in preparing a highly ordered two-dimensional (2D) carbon/TiO (C/TiO) nanosheet composite using commercially available organic molecules with multifunctional groups and taking advantage of the wedge effects, oxidative polymerization, and carbonization. An experiment was conducted to validate the excellent performance of this 2D composite with respect to interfacial energy storage.

Two-Dimensional Layered Ultrathin Carbon/TiO Nanosheet Composites for Superior Pseudocapacitive Lithium Storage.

Intercalation of carbon nanosheets into two-dimensional (2D) inorganic materials could enhance their properties in terms of mechanics and electrochemistry, but sandwiching these two kinds of materials in an alternating sequence is a great challenge in synthesis. Herein, we report a novel strategy to construct TiO nanosheets into 2D pillar-layer architectures by employing benzidine molecular assembly as pillars. Then, 2D carbon/TiO nanosheet composite with a periodic interlayer distance of 1.

An all-nanosheet OER/ORR bifunctional electrocatalyst for both aprotic and aqueous Li-O batteries.

Rechargeable lithium-oxygen (Li-O2) batteries are receiving intense interest because of their high energy density. A highly efficient catalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is a key factor influencing the performance of Li-O2 batteries. In this work, a facile synthesis of an all-nanosheet architecture electrocatalyst constructed from a monolayer ruthenium dioxide (RuO2) nanosheet with a nitrogen doped sulfonated graphene nanosheet (RuO2-NS-GNS) has been developed for Li-O2 batteries.

Selected deposition of high-quality aluminum film by liquid process.

For generation of a fine aluminum pattern by conventional vacuum processing, it is necessary not only to use complex and costly instruments but also to perform an additional etching process, which may result in physical and chemical damage to the target film surface. Herein we report a simple solution process for the selected deposition of an Al pattern. Al is obtained from the decomposition of alane under dehydrogenation catalysis of a Pt nanocrystalline pattern on a substrate at ∼105-120 °C, while the self-decomposition of alane in solution is avoided in the presence of high-boiling-point amine.
