MgF2@C anodeless electrode is prepared for all-solid-state batteries. This MgF2@C prepared via sonochemical synthesis achieves enhanced dispersion of nanodot MgF2 on the carbon black surface. Mg-Li alloy and LiF converted from MgF2 during the lithiation step improve charging kinetics. The anodeless electrode with MgF2@C shows lower overpotentials,...
Tri(2,2,2-trifluoroethyl) borate is identified as a new multifunctional additive for stable cycling of high energy density Li–S batteries. It forms strong complexes with all polysulfide and smooth the otherwise dramatically changing polysulfide solubilities during battery cycling. These complexes improve the kinetics of thick sulfur cathodes under...
This review summarizes the variety of large-scale synthesis strategies of photo/electrocatalysts, and the important advances in systematic reactor configurations are emphasized. In addition, the rapid selection of high-performance catalysts with the help of machine learning provides a low-cost route for the accuracy of large-scale catalyst preparation...
Lithium–sulfur (Li–S) batteries have reached the stage of practical development. To address the new challenges faced by the electrolyte in these batteries under practical conditions, this review provides a comprehensive analysis of the practical development process of Li–S batteries, outlines the core challenges, and summarizes the multifunctional...
To build high-capacity, long-life all-solid-state lithium–selenium batteries, lithium iodide (LiI) is introduced into the cathode as an active additive. LiI actively enhances interfacial Li+ transport and provides rich catalytic sites for the selenium composite cathode while partially acting as a redox-active component in the cathode, thereby accelerating...
Achieving uniform and dense metal deposition is essential for improving the stability of metal anodes. A novel Zn anode, engineered with optimal crystal steps, finely tunes the Zn nucleation and growth processes. This design promotes initial epitaxial Zn deposition along the steps, effectively regulating subsequent smooth and rapid Zn deposition....
