Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

open access: yesAdvanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...

Dynamic Cycling of Ultrathin Li Metal Anode via Electrode–Electrolyte Interphase Comprising Lithiophilic Ag and Abundant LiF under Carbonate‐Based Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
The silver trifluoromethanesulfonate (AgTFMS) simultaneously forms metallic Ag and abundant LiF on the Li metal surface after dissolution in carbonate‐based electrolyte, whereas lithium trifluoromethanesulfonate (LiTFMS) only generates LiF‐rich solid‐electrolyte interphase (SEI).

Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

Scandium Induced Structural Disorder and Vacancy Engineering in Li3Sb – Superior Ionic Conductivity in Li3−3xScxSb

open access: yesAdvanced Energy Materials, EarlyView.
A superionic conductivity of 42 mS cm−1 at 298 K is reported for Li2.55Sc0.15Sb, which exceeds the highest ionic conductivity reported for a solid Li‐ion conductor to date by 10 mS cm−1. In the series Li3−3xScxSb (0 < x ≤ 0.15), the gradual incorporation of Sc facilitates vacancy formation, converting pristine Li3Sb from an electrical to an ionic ...

Floatable Protective Layers: a Strategy to Minimize Solid Electrolyte Interphase Growth and Maximize the Lithium Utilization

open access: yesAdvanced Energy Materials, EarlyView.
The floatable protective layer is synthesized via surfactant‐assisted solvent drying of a porous conductive layer. It promotes preferential deposition of lithium beneath the layer, while enabling solid electrolyte interphase formation above it. This design minimizes direct electrolyte contact with freshly deposited lithium, reducing side reactions and ...

Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.
