This work demonstrates how operando magnetometry techniques can track the dynamic electron transfer during transition-metal catalysis in real time and investigate the charge storage mechanism in a conversion-type battery material. The findings share here to provide a fundamental understanding of important electrochemical processes and useful guidelines...

Grain boundaries and surfaces are critical to the properties of polycrystalline solid electrolytes (SEs). A survey of 590 surfaces and grain boundaries of SEs demonstrates bulk SEs' properties alone are not representative for a complete assessment of these materials. Changes in mechanical and electronic properties at grain boundaries are extremely...

This study presents a novel integrated system for carbon capture and conversion (iCCC) technology, which stands out by bridging the gap in existing technology through a comprehensive approach that combines CO2 capture, release, and in situ catalytic conversion within a single, continuous gas-liquid-solid reaction system based on thermal catalysis...

Porous poly(acrylonitrile) nanosheets (PPNS) enriched with conjugated C═C/C═N groups is designed on PP separator by spray-coating. The polar N-containing groups in PPNS exhibit lithiophilic properties and effectively accelerate Li+ transport kinetics. Therefore, PPNS with porous 2D nanosheet structure ensures a sufficient and uniform Li+ concentration...

In this work, Song et al. reported a surface-modified hard carbon anode comprising atomic Co sites and rich curvature characteristics. Among them, the coated layer facilitates the formation of NaF-rich SEI and the transportation kinetics of Na+ at the electrode/electrolyte interface. The synthesized optimal sample exhibits a superior low-temperature...

Weakly solvating electrolyte derived from tetrahydrofuran has low interface energy, enabling solvated-Li+ co-intercalate into the carbon film and inducing the formation of a robust SEI film with inorganic rich. Carbon film anode achieves ultra-high Li intercalation capacity of 236.5 mAh g−1 at 0–0.1 V and reversible cycling of hybrid lithium-ion/metal...
