Phase‐Change Solvents for Thermally Switchable Ion Conduction in Organogels

open access: yesAdvanced Materials, EarlyView.
Organogels containing salts dissolved in phase‐change solvents exhibit thermally switchable ion conduction. The organogels, which display an over 10 000‐fold on‐off ratio and high cycling stability, can be synthesized with a wide range of salts and customizable conductivity/temperature relations for applications in ionotronics and energy storage ...

A Quasi‐Solid Ionic Liquid‐Polymer Hybrid Electrolyte for Shuttle‐Free and Dendrite‐Free Aqueous Zinc─Bromine Batteries

open access: yesAdvanced Materials, EarlyView.
A quasi‐solid ionic liquid‐polymer hybrid electrolyte is proposed to achieve shuttle‐free and dendrite‐free aqueous Zn─Br batteries. Synergetic effects between Zn2+ selective conduction of polyanionic network and polybromide complexing additive suppress the shuttle effect and improve Zn reversibility.

Stiff to Soft: A Protein‐Based Buffer Layer for Improving the Long‐Term Performance of Microneedle Sensors

open access: yesAdvanced Materials, EarlyView.
To enhance stability and long‐term biocompatibility of wearable microneedle sensors, a crosslinking‐recombination bovine serum albumin material is used as a buffer layer coated on microneedle sensors. This coating layer possesses a unique stiff‐to‐soft transition function balancing the mechanical stiffness desired for puncturing and soft required for ...

Efficient Non‐Invasive Rejuvenation of Spent Lithium Iron Phosphate Batteries Through Controlled Overdischarge

open access: yesAdvanced Materials, EarlyView.
This strategy rejuvenates spent lithium iron phosphate battery by non‐invasively targeting Li+ trapped within the solid‐electrolyte interphase (SEI). This method mitigates copper dissolution and reduces Li/Fe antisite defects, achieving 9.56% capacity recovery and 214 cycles lifespan extension. The process requires only 3 MJ kg−1 of energy and emitting

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...
