A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

open access: yesAdvanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

open access: yesAdvanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.
