Effects of Nanoparticle Geometry and Size Distribution on Diffusion Impedance of Battery Electrodes

, 2012
The short diffusion lengths in insertion battery nanoparticles render the capacitive behavior of bounded diffusion, which is rarely observable with conventional larger particles, now accessible to impedance measurements. Coupled with improved geometrical

Multi‐Faceted Binder Enhancement via Slurry‐Applicable Thiol‐Ene Click Chemistry for Low‐Pressure‐Operable All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
Cross‐linked binders with enhanced resiliencies under low operating pressures are designed via in situ thiol‐ene click reactions within slurries. Cross‐linking improves the Young's moduli and elasticities of the styrene‐butadiene rubber binders, effectively mitigating interparticle delamination within the composite cathodes induced by volumetric ...

Sulfur Reduction Pathways and Through-thickness Distribution in Positive Composite Electrodes of All-solid-state Li–S Batteries: Elucidation of Two-stage Discharge Plateaus

Electrochemistry
Sulfur positive electrodes in liquid-type lithium–sulfur (Li–S) batteries exhibit two discharge plateaus at approximately 2.4 and 2.1 V (vs. Li). However, conventional sulfur composite electrodes in all-solid-state Li–S batteries typically do not display

Unique compounds functionalized with three-membered cyclic structures

Green Chemical Engineering
Three-membered cyclic compounds are a fascinating class of compounds: they have the maximum torsional and angular strain (sp3 hybridization but bond angles deviate from 109°28’), and possess unique physical and chemical properties.

Hydrogen‐Bond‐Rich Supramolecular Multiblock Copolymers Facilitate Rapid Zn2+ Migration in Quasi‐Solid‐State Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

Advanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.
