Abstract
Multilayered porous separators consisting of cellulose nanofibers (CNF) and SiO 2 coating are fabricated for lithium-ion batteries (LIBs) as an eco-friendly alternative to conventional polyolefin separators. Employing a sol-gel synthesis method, SiO 2 nanoparticles are intricately arranged on CNF to create core-shell structured CNF-SiO 2 composites. Simple binder-free CNF-SiO 2 surface coated composite separators are obtained via alternating sequential vacuum filtration of CNF suspensions and the nanocomposite coating functional layers, resulting in bi- and tri-layered separators. CNF entangled structure determines the pore architecture of CNF-SiO 2 as a molecular template, while simultaneously tailoring the size distribution of pores and fibers within the separator, thus optimizing Li-ion transport pathways. By combining core-shell structured CNF-SiO 2 nanocomposites as a functional layer with CNF separators, the resulting multilayer separators significantly improve the electrochemical stability of LIBs due to the effective suppression of electrolyte decomposition and dendrite growth on the Li metal surface. This approach simplifies material sourcing and production processes, making it particularly attractive for large-scale manufacturing for LIBs separators from carbohydrate precursors extracted from biomass. This study highlights the potential of chemically modified cellulose-based nanostructures as high-performing upcycled separators for energy storage, resulting in their possible commercial applications.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
