A New Quasi‐Solid Polymer Electrolyte for Next‐Generation Na–O2 Batteries: Unveiling the Potential of a Polyamide‐Polyether System

open access: yesAdvanced Science, EarlyView.
This study introduces a novel, sustainable Pebax1657‐based quasi‐solid polymer electrolyte (QSPE) that enhances the performance and safety of sodium–oxygen (Na–O2) batteries. The developed QSPE shows improved Na+ ion transport, reduced overpotentials, and better cycling stability compared to the conventional liquid systems, highlighting its potential ...

Expansion Force‐Based Adaptive Multistage Constant Current Fast Charging with Lithium Plating Detection for Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This article presents an adaptive multistage constant current (MCC) charging method for lithium‐ion batteries, using expansion force feedback to detect lithium plating in real time. It outlines how force‐derivative thresholds enable self‐regulation of the charging rate, increasing speed by 50% without damage.

Laser‐Induced Coal‐Based Porous Graphene as Anode Toward Advanced Lithium‐Ion Battery

open access: yesAdvanced Science, EarlyView.
A one‐step laser‐induced strategy is reported to prepare porous graphene by utilizing bituminous coal as a precursor (LIG‐B). Laser irradiation transforms coal into graphene, with small molecules from the polymer separating, recombining in gas and forming 3D porous graphene upon quick gas release.

Photovoltaic and Photomultiplication Dual‐Mode Near‐Infrared Organic Detectors with Large Dynamic Range for Intensive and Faint Light Sensing

open access: yesAdvanced Science, EarlyView.
A photovoltaic/photomultiplication dual‐mode organic photodetector is developed by integrating two different organic bulk‐heterojunctions, one introduces the photovoltaic effect, and the other triggers photomultiplication charge generation in the stacked device at different voltage polarities.

Improving the Thermoelectric Properties of Conjugated Polymer Thin Films by Dip Coating – but not through Alignment

open access: yesAdvanced Electronic Materials, EarlyView.
The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.
