A Unified Polymer Hydrogel Electrolyte Integrating Robust Adhesion, Self‐Healing, and Oxygen Permeability in Flexible Neutral Zn‐Air Batteries

Advanced Materials, EarlyView.
Flexible neutral Zn‐air batteries achieving a remarkable 3000‐cycle lifespan and withstanding 1000 bending cycles are reported. This performance is realized by employing a 3D physically cross‐linked neutral hydrogel electrolyte that integrates high adhesion, self‐healing, O2 permeability, and CO2 tolerance to resolve critical stability challenges ...

Toward a Unified Mechanistic Understanding of Polymer Electrolytes for Advanced Solid‐State Batteries

Advanced Materials, EarlyView.
Polymer electrolytes (PEs) are often indiscriminately grouped as “solid polymer electrolytes (SPEs)”, despite fundamental differences in their ion‐transport mechanisms. This Perspective establishes a mechanism‐based framework that distinguishes gel, quasi‐solid, and all‐solid polymer electrolytes based on their dominant ion‐transport pathways.

Surface‐Functionalized LLZO‐Incorporated Multilayer Composite Solid Electrolytes for Dendrite Suppression and Efficient Ionic Conduction in Lithium–Metal Batteries

Advanced Materials, EarlyView.
A soft–hard tri‐layer composite electrolyte that couples fast Li+ transport with reinforced interfacial stability to enable high‐conductivity, mechanically robust, dendrite‐free lithium‐metal batteries. ABSTRACT The development of solid polymer electrolytes is central to safe, high‐energy lithium‐metal batteries (LMBs); however, persistent challenges ...

Nanodiamonds suppress the growth of lithium dendrites

Nature Communications, 2017
Lithium metal is an ideal anode material for rechargeable batteries but suffer from the growth of lithium dendrites and low Coulombic efficiency. Here the authors show that nanodiamonds serve as an electrolyte additive to co-deposit with lithium metal ...

A scalable 3D lithium metal anode

Energy Storage Materials, 2019
Abstract A scalable 3D electrode to serve as a lithium metal host is developed to enable stable lithium metal cycling. The electrode is simply fabricated by coating a slurry of well mixed LiNO3, carbon black, and PVDF on the Cu foil. The pores in the electrode serve as lithium metal hosts while the LiNO3 particles act both as a structural skeleton ...

Macroscopically uniform interface layer with Li+ conductive channels for high-performance Li metal batteries

Nature Communications
The numerous grainboundaries solid electrolyte interface, whether naturally occurring or artificially designed, leads to non-uniform Li metal deposition and consequently results in poor full-battery performance.

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

Advanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Design of High‐Energy Anode for All‐Solid‐State Lithium Batteries–A Model with Borohydride‐Based Electrolytes

Advanced Materials Interfaces, EarlyView.
This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
