Buried interface engineering towards stable zinc anodes for high-performance aqueous zinc-ion batteries.

The dendrite and corrosion issues still remain for zinc anodes. Interface modification of anodes has been widely used for stabilizing zinc anodes. However, it is still quite challenging for such modification to simultaneously suppress zinc dendrites and corrosion issues.

Tailored design of NHS-SS-NHS cross-linked chitosan nano-hydrogels for enhanced anti-tumor efficacy by GSH-responsive drug release.

The traditional chemotherapeutic agents' disadvantages such as high toxicity, untargeting and poor water solubility lead to disappointing chemotherapy effects, which restricts its clinical application. In this work, novel size-appropriate and glutathione (GSH)-responsive nano-hydrogels were successfully prepared via the active ester method between chitosan (containing -NH) and cross-linker (containing NHS). Especially, the cross-linker was elaborately designed to possess a disulfide linkage (SS) as well as two terminal NHS groups, namely NHS-SS-NHS.

Suppressed Electrolyte Decomposition Behavior to Improve Cycling Performance of LiCoO under 4.6 V through the Regulation of Interfacial Adsorption Forces.

Alleviating the decomposition of the electrolyte is of great significance to improving the cycle stability of cathodes, especially for LiCoO (LCO), its volumetric energy density can be effectively promoted by increasing the charge cutoff voltage to 4.6 V, thereby supporting the large-scale application of clean energy. However, the rapid decomposition of the electrolyte under 4.

NaV(PO)-decorated NaV(PO)F as a high-rate and cycle-stable cathode material for sodium ion batteries.

Since NaV(PO) (NVP) possesses modest volume deformation and three-dimensional ion diffusion channels, it is a potential sodium-ion battery cathode material that has been extensively researched. Nonetheless, NVP still endures the consequences of poor electronic conductivity and low voltage platforms, which need to be further improved. On this basis, a high voltage platform NaV(PO)F was introduced to form a composite with NVP to increase the energy density.

Enhancing Sodium-Ion Transport by Hollow Nanotube Structure Design of a VS@C Anode for Sodium-Ion Batteries.

VS has received extensive attention in the field of sodium-ion batteries (SIBs) due to its two-dimensional (2D) layered structure, and weak van der Waals forces between V-S accelerate the transport of sodium ions. However, the long-term cycling of VS still suffers from volume expansion and low conductivity. Herein, a hollow nanotube VS@C (H-VS@C) with improved conductivity was synthesized by a solvothermal method to alleviate cracking caused by volume expansion.

-Constructed Multifunctional Interface for High-Voltage 4.6 V LiCoO.

Due to high volumetric energy density, the major market share of cathode materials for lithium-ion batteries is still dominated by LiCoO (LCO) at a 3C field. However, a number of challenges will be triggered if the charge voltage is increased from 4.2/4.

Adjusting Crystal Orientation to Promote Sodium-Ion Transport in V S @Graphene Anode Materials for High-Performance Sodium-Ion Batteries.

Sodium-ion batteries (SIBs) have inspired the potential for widespread use in energy storage owing to the advantages of abundant resources and low cost. Benefiting from the layered structure, 2D-layered materials enable fast interlayer transport of sodium ions and thus are considered promising candidates as anodes for SIBs. Herein, a strategy of adjusting crystal orientation is proposed via a solvothermal method to improve sodium-ion transport at the edge of the interlayers in 2D-layered materials.

Micropatterned PEDOT with Enhanced Electrochromism and Electrochemical Tunable Diffraction.

Micro-nanofabrication of conductive polymers (CPs) with functional structures is in great demand in organic electronic devices, micro-optics, and flex sensors. Here, we report the fabrication of micropatterned poly(3,4-ethylenedioxythiophene) (PEDOT) and its applications on flexible electrochromic devices and tunable diffractive optics. The localized electropolymerization of 3,4-ethylenedioxythiophene at the electrode/agarose gel stamping interface through an electrochemical wet stamping (E-WETS) technique is used to fabricate PEDOT with functional microstructures.
