Single Lithium-Ion Conductor Decorated LiMnO with High Selectivity and Stability for Electrochemical Lithium Extraction.

Spinel LiMnO (LMO) is commonly used for electrochemically extracting lithium ions from brine. However, its cycle stability is significantly reduced due to Mn dissolution. Here, we report high-performance LMO particles decorated by LiAlGe(PO) (LAGP) as an electrode for electrochemical lithium extraction.

Two-Dimensional Sulfonate-Functionalized Metal-Organic Framework Membranes for Efficient Lithium-Ion Sieving.

Two-dimensional (2D) membranes have shown promising potential for ion-selective separation but often suffer from the trade-off between permeability and selectivity. Herein, we report an ultrathin 2D sulfonate-functionalized metal-organic framework (MOF) membrane for efficient lithium-ion sieving. The narrow pores with angstrom precision in the MOF assist hydrated ions to partially remove the hydration shell, according to different hydration energies.

High-Performance Flexible Polymer Memristor Based on Stable Filamentary Switching.

Polymer-based atomic switch memristors via the formation/dissolution of atomic-scale conductive filaments are considered as the leading candidate for next-generation nonvolatile memory. However, the instability of conductive filaments of incomplete bridge makes their switching performances unsatisfied. In this work, we report a flexible polymeric memristor using polyethylenimine incorporated with silver salt.

Niobium Tungsten Oxides for Electrochromic Devices with Long-Term Stability.

There is a keen interest in the use of electrochromic materials because they can regulate light and heat, thereby reducing the cooling and heating energy. However, the long response time, short cycle life, and high power consumption of an electrochromic film hinder its development. Here, we report an electrochromic material of complex niobium tungsten oxides.
