Anode‐Free All‐Solid‐State Batteries: Understanding Limitations and Charting a Path to Enhanced Performance

open access: yesSmall, EarlyView.
This review examines four factors that drive interfacial instability in sulfide‐based anode‐free all‐solid‐state batteries and thoroughly reviews corresponding performance‐enhancing strategies. The strategies are organized as follows: (1) interlayer engineering, (2) pressure‐regulating buffer layers, (3) other methods, including sacrificial cathodes ...

Synergistic Design of a SiO2–CNT–Amorphous Carbon 3D Host for Stable SEI Formation and Long‐Term Cycling Stability of Lithium Metal Anodes

open access: yesSmall, EarlyView.
SiO2@AC‐CNT microspheres, produced by spray pyrolysis and carbonization, present a 3D host where SiO2 is uniformly embedded within the CNT‐amorphous carbon framework. The architecture balances electronic conductivity and lithiophilicity, guiding uniform, dendrite‐free lithium deposition.

Improved Stability in LiX‐NbCl5 (X = Cl, Br) Glass‐Ceramic Electrolytes Through Anion Mixing for Solid‐State Batteries

open access: yesSmall, EarlyView.
Chlorine gas evolves at the end of charge in solid‐state batteries with LiNbCl5X (X = Cl−, Br−) catholytes. This can be mitigated to some extent by introducing bromine and has a positive effect on electrochemical stability but does not impair ionic conductivity.

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

open access: yesSmall, EarlyView.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

Manganese Oxide Catalysts for Lithium–Oxygen Batteries: Structures, Mechanisms, and Reaction Pathway Engineering

open access: yesSmall, EarlyView.
How do the morphologies, crystal structures, and electronic properties of manganese oxides influence oxygen reaction pathways in lithium–oxygen batteries (LOBs)? This review systematically summarizes structure‐dependent catalytic mechanisms and recent engineering strategies, highlighting how defect engineering, compositional modulation, and reaction ...
