Controllable Carbon Shell Encapsulation via Rapid Joule Heating Calcination for High‐Performance Asymmetric Supercapacitor With Suppressed Self‐Discharge and Robust Cycling Stability

Advanced Science, EarlyView.
The H‐Fe3O4@C negative electrode and H‐NiCo2S4@C positive electrode are designed through a controllable carbon shell encapsulation strategy. The as‐constructed asymmetric supercapacitor presents robust cycling stability with 93.7% capacity retention after 25 000 cycles.

3D‐Mixer‐Assisted High‐Entropy Doping of LiNiO2 for Co‐Free Ni‐Rich Cathodes in Lithium‐Ion Batteries

Advanced Science, EarlyView.
High‐entropy doping of Co‐free Ni‐rich LiNiO2 cathodes is achieved through a scalable 3D mixing process. Multi‐element incorporation stabilizes the layered structure, alleviates Li/Ni disorder and electrode swelling, and enhances cycling stability. This approach underscores the potential of high‐entropy strategies to deliver structurally robust and ...

Coupled Electronic and Ionic Conductivity in Strain‐Stiffening Hydrogels

Advanced Science, EarlyView.
A soft PVA–PABA hydrogel is developed that couples tissue‐like strain‐stiffening mechanics with dual ionic–electronic conduction. Dynamic boronic crosslinks enable self‐assembled percolative pathways, producing deformation‐responsive resistance with a stabilization plateau at stiffening onset, revealing alignment‐assisted charge transport and advancing

Metal Ion‐Induced Fast Gelation of 2D MnO2 Nanosheets With Cationic Vacancies for Durable Aqueous Zinc‐Ion Batteries

Advanced Science, EarlyView.
We report Mn‐deficient aerogels by inducing the first gelation of MnO2 nanosheets in solution using divalent metal ions as crosslinking agents, thereby inhibiting nanosheet restacking and enhancing surface utilization. Benefiting from abundant Mn vacancies and 3D porous structures, the A‐MnO2 cathode exhibits improved conductivity, fast reaction ...

Vacancy‐Driven Ni Exsolution in Prussian Blue Analogues Creates Cooperative Defect–Metal Sites for Alkaline Hydrogen Evolution

Advanced Science, EarlyView.
Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...
