Breaking the Capacity Limit for WO3 Anode‐Based Li‐Ion Batteries Using Photo‐Assisted Charging

open access: yesAdvanced Functional Materials, EarlyView.
This image illustrates a photo‐assisted rechargeable lithium‐ion battery. (a) shows the battery structure, where light enhances electron‐hole generation in the anode, boosting ion flow. (b) compares discharging performance, revealing over 60% higher capacity under light compared to dark conditions, showcasing the benefit of light‐assisted energy ...

Mg Substitution Improves the Surface Stability of High‐Voltage Spinel Cathodes under Accelerated Aging Conditions

open access: yesAdvanced Functional Materials, EarlyView.
LiNi0.5Mn1.5O4 lithium‐ion battery cathodes exhibit poor cycling stability due to surface reconstruction and electrolyte degradation at high voltage. This work demonstrates that partial Ni substitution with Mg prevents surface reconstruction and creates a corrosion‐resistant surface layer during the early stages of cycling, hence reducing electrolyte ...

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and
