Summary: Pure cellulose nanofiber (CNF) separators for high-performance lithium-ion batteries (LIBs) were prepared using CNF as the matrix and tert-butyl alcohol (TBA) as the dispersion medium by a facile filtration method. The freeze-dried separator at -80 degrees C with TBA as the dispersion medium (TBA-FD) exhibited the best performance, with high porosity, electrolyte uptake, and ionic conductivity. The CNF separators showed good thermal stability and demonstrated superior cycling stability and rate performance in LIBs.
