Unveiling the Li/Electrolyte Interface Behavior for Dendrite‐Free All‐Solid‐State Lithium Metal Batteries by Operando Nano‐Focus WAXS

Advanced Science
Poly(ethylene oxide) (PEO)‐based solid composite electrolytes suffer from poor conductivity and lithium dendrite growth, especially toward the metallic lithium metal anode.

A microscopic view of diffusion and failure mechanisms of lithium anodes in solid-state batteries

eScience
Although all-solid-state lithium metal batteries (SSLBs) have long been regarded as successors of the commercially available lithium-ion batteries (LIBs), SSLBs do not yet deliver sufficient and competitive performance.

Functional lithiophilic polymer modified separator for dendrite-free and pulverization-free lithium metal batteries

, 2021
Severe performance drop and fire risk due to the uneven lithium (Li) dendrite formation and growth during charge/discharge process has been considered as the major obstacle to the practical application of Li metal batteries. So inhibiting dendrite growth

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Origin of dendrite-free lithium deposition in concentrated electrolytes

Nature Communications, 2023
AbstractThe electrolyte solvation structure and the solid-electrolyte interphase (SEI) formation are critical to dictate the morphology of lithium deposition in organic electrolytes. However, the link between the electrolyte solvation structure and SEI composition and its implications on lithium morphology evolution are poorly understood.

Effects of LLZO Microstructure Porosity, LLZO/Li‐Metal Interfacial Polarization Resistance, and Applied Areal Current Density on Li‐Metal Dendrite Formation in LLZO Bilayer Symmetric Cells

Advanced Functional Materials, EarlyView.
The effects of solid‐state electrolyte architecture and electrolyte/electrode interfacial polarization resistance on Critical Current Density and the risks for “interfacial” and “internal” Li‐metal dendrite formation were investigated in simulations of FIB‐reconstructed porous‐dense Li7La3Zr2O12 (LLZO) “bilayers”, providing insight for full cells ...

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

Partly lithiated graphitic carbon foam as 3D porous current collectors for dendrite-free lithium metal anodes

Electrochemistry Communications, 2019
Though lithium (Li) metal is an ideal anode material for next-generation rechargeable batteries, its application has been seriously limited by security and cyclability issues as the result of uncontrollable Li dendrite growth. To solve this problem, this
