Twenty‐Minute Microwave‐Enabled Dual‐Anion Nickel Sulfoselenide Anodes for High‐Capacity Sodium/Potassium‐Ion Batteries and Durable Pouch Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐anion‐assisted strategy is proposed for designing bi‐functional high‐performance anodes. The preparation of NiSSe/N‐C within 20 min demonstrates rapid Na+/K+ reaction kinetics, exceptional rate capability, and remarkable cycling stability. Nickel‐based materials are promising anode candidates for sodium‐ion batteries and potassium‐ion batteries ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
