Unraveling Microporosity in Hard Carbons: Insights Into Sustainable Sodium‐Ion Battery Materials

open access: yesBatteries &Supercaps, Volume 9, Issue 9, September 2026.
Hidden microporosity in hard‐carbon anodes for sodium‐ion batteries is revealed by small‐angle X‐ray scattering combined with Ruland–Smarsly analysis, including closed pores inaccessible to gas adsorption. Comparing petroleum‐derived and biowaste‐derived carbons links nanoscale disorder, surface area, and pore architecture to sodium storage ...

Microstructure‐Tailored Avocado Pit‐Derived Carbon via Hydrothermal Pre‐Carbonization for Enhanced Potassium Storage Performance

open access: yescMat, Volume 3, Issue 3, September 2026.
ABSTRACT Potassium‐ion batteries (PIBs) are regarded as a highly promising energy storage technology owing to abundant resources and low redox potential. Nevertheless, potassium's large ionic radius leads to sluggish diffusion kinetics and severe volume expansion during insertion and extraction. Therefore, exploring advanced anode materials with robust

Role of Core and Surface States Electronic Structure in the Tunable Optical Properties of Nitrogen‐Doped Carbon Dots

open access: yesChemPhotoChem, Volume 10, Issue 9, September 2026.
This work provides insight into the photoluminescence mechanism of nitrogen‐doped carbon dots derived from PTCDA and urea. The materials exhibit a dual‐emission system composed of dominant, excitation‐independent core emission and secondary excitation‐dependent surface/state emission.

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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
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.
