Bio‐Inspired Carbon Spheres Enable Active Sites Multiscale‐Anchoring and Pre‐Reduction

open access: yesCarbon Energy, EarlyView.
Combining the wet‐spinning technique with a “bionic design” concept, a bio‐inspired carbon sphere support with internal finger‐shaped pores and external craquelure structures is designed and constructed, and the corresponding carbon sphere reactor is fabricated through the multiscale anchoring and the pre‐reduced promoting, and verified for application

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)
