Mitigating Planar Gliding in Single‐Crystal Nickel‐Rich Cathodes through Multifunctional Composite Surface Engineering

A passivation shell, comprising a surface fast ion conductor Li1.25Al0.25Ti1.5O4 layer and a near-surface rock-salt region, is established through co-infiltrating Al/Ti into LiNi0.83Co0.07Mn0.1O2 (SNCM). The composite surface engineering effectively suppresses planar gliding and microcracking, enabling fast ion transport and improved structural stability...

Polymers for Aqueous Zinc‐Ion Batteries: From Fundamental to Applications Across Core Components

Polymers serve as critical compositional materials in aqueous zinc-ion batteries. Their structure, molecular constitution, and hydrophilicity require special design for these water-involving batteries. This review covers complete research progress explicitly on polymer materials in the five core components of aqueous zinc-ion batteries, with the aim...

Unveiling Favorable Microenvironment on Porous Doped Carbon Nanosheets for Superior H2O2 Electrosynthesis in Neutral Media

The unique micro/mesoporous structure of the carbon nanosheets can facilitate the enrichment of oxygen to increase proton consumption, thereby forming a local alkaline-like microenvironment. As a result, the N,O-CNS0.5 sample exhibits excellent catalytic 2e− ORR activity in a neutral medium, with a minimal overpotential (50 mV), high H2O2 selectivity...

Directing Fluorinated Solid Electrolyte Interphase by Solubilizing Crystal Lithium Fluoride in Aprotic Electrolyte for Lithium Metal Batteries

The feasibility of crystal LiF as salt in directly fluorinating SEI is verified, and its fluorination mechanisms as well as anti-acidification of electrolyte are explored. The dissolved LiF is encapsulated by solvent-/salt-derived organic skins to promote the fluorinated SEI. Meanwhile, the presence of LiF in electrolytes suppresses the production...
