Unsaturated Coordination Oxygen in Zn─V─O Vacancy Clusters Enables Superb Zinc Storage Capability

Advanced Science, EarlyView.
Zn3(VO4)2 with Zn─V─O vacancy clusters was synthesized and innovatively applied as cathode material in aqueous Zn‐ion batteries. In‐situ XRD, HRTEM and ab initio molecular dynamics simulations unveil the double reaction mechanism of zinc ions. Adsorption of zinc ions on unsaturated coordination O and H+ on O in ‐VO4 contributes to the main capacity. It

High‐Performance Recycling Biobased Photopolymers for 3D Printing

Advanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...
