The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.

Harnessing Natural Wood Architecture: A Self‐Supporting, Hierarchically Porous NiFe@Carbon Capacitive Anode Enhances Electricity Generation and Storage in Microbial Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study reports a mild “Zn(NO3)2 interlayer‐expansion” strategy combined with electrodeposition to produce a self‐supporting capacitive anode (NiFe@PC) that preserves the wood's native low‐tortuosity channels. The retained native architecture expands niches for microbial colonization.
