Simulation-guided SiOx–graphite anode design for mitigating reaction heterogeneity and enhancing fast-charging performance in lithium-ion batteries

SiO x –graphite composite anodes offer high energy density and improved rate capability owing to the high theoretical capacity of SiO x (∼1400 mAh g −1 ); however, their cycle life under fast-charging conditions remains severely limited. This study presents a simulation-guided de...

Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

ABSTRACT Despite the fact that only 2% of active sites can satisfy hydrogen oxidation reaction (HOR) activity thanks to fast kinetics, the fuel cell anode is still dependent on catalysts with large amounts of platinum (Pt). Herein, a minimal‐cost ruthenium catalyst bearing ultral...
