Separators have garnered substantial attention from researchers and developers in regard to their crucial role in the safety of lithium-ion batteries. In this study, a composite separator was prepared by coating cubic Al2O3 nanoparticles on non-woven poly(ethylene terephthalate) (PET) via a simple dip-coating process. The basic properties of the Al2O3-coated PET non-woven composite separator were...
A kind of composite melt-blown nonwoven fabric with larger pore size compared to commercial microporous polyolefin-based separators was prepared in order to improve the cell performance and safety of Li-ion batteries at high C-rate. Heavy-weight melt-blown nonwoven fabrics were directly assembled into coin-type Li-ion batteries. Then light-weight melt-blown nonwoven fabrics were chosen as the substrate...
