Coordination‐Gated MOF@COF Functional Separators for Regulating Ion Flux in Lithium Metal Batteries

ABSTRACT Functional separators that regulate ion transport before lithium ions (Li + ) reach the lithium metal surface are critical for mitigating dendritic deposition and interfacial instability in lithium metal batteries. However, most separator designs mainly emphasize Li + af...

Pioneering MOF-303 in Lithium–Sulfur Batteries: Coordination Defect Engineering Enables Accelerated Sulfur Redox and Dendrite-Free Plating

Abstract Lithium–sulfur (Li–S) batteries are severely hindered by the shuttle effect of lithium polysulfides (LiPSs) and uncontrolled lithium dendrite growth. Herein, a defect-engineered MOF-303 (D-MOF-303) modified separator is developed via a ball-milling strategy to simultaneo...

Weakening conjugation of organic cyclic additives towards advanced aqueous zinc-ion batteries

Aqueous zinc-ion batteries (AZIBs) offer a safe and economical option for energy storage but face zinc dendrites and parasitic reactions. Here we report 1,3,5-tris(2-hydroxyethyl) isocyanurate (THI) as an electrolyte additive that delivers environment-dependent dual-state protect...

Data‐Efficient Cycle‐Level Capacity Prediction Using 1D Deep Convolutional Network

Fundamental battery research is constrained by the time‐consuming process of long‐term charge–discharge cycling stability testing. Here, we introduce DeepBat, a deep learning framework designed to shorten cycling tests by achieving accurate, long‐horizon prediction of cycle‐level...

Anchored Oxygen‐Release‐Suppression Phase Stabilizing High‐Voltage Ni‐Rich Cathode Materials

ABSTRACT The Ni‐rich LiNi x Co y Mn 1−x−y O 2 (x ≥ 0.9) cathode materials (NCMs) have been considered promising for next‐generation Li‐ion batteries owing to their high‐energy density. However, their practical application is hindered by gas evolution and rapid capacity degradatio...

Carbon-rich carbon nitride for singlet-oxygen-driven photocatalytic degradation of benzophenone-3 and coral vitality recovery

Coral reefs, vital marine ecosystems, are increasingly threatened by global warming and chemical pollutants such as benzophenone-3 (BP-3), a widely used UV filter. To address this challenge, we present a carbon-doped graphitic carbon nitride (g-C3N4) photocatalyst with efficient...
