Free‐Standing, Foldable V2O3/Multichannel Carbon Nanofibers Electrode for Flexible Li‐Ion Batteries with Ultralong Lifespan

“…In addition, SEM observations under low magnification ( Figure S2, Supporting Information) demonstrate that V 2 O 3 /MCCNFs-3 electrode film exhibits much rougher surface feature than that of the electrode film obtained by the conventional method of doctor-blade, beneficial for the infiltration of electrolyte, enhancing the mechanical interlocking and decreasing the interfacial resistance by improving the adhesion between the electrode materials. [30][31][32] Figure 3a shows the X-ray diffraction (XRD) patterns of V 2 O 3 /MCCNFs-3 composites, which match very well with the standard data from the rhombohedral crystalline phase V 2 O 3 (JCPDS 34-0187). [33] The XRD results suggest that the pure phase of V 2 O 3 electrode is successfully prepared.…”

Electrospun PVDF Nanofibers for Piezoelectric Applications: A Review of the Influence of Electrospinning Parameters on the β Phase and Crystallinity Enhancement

“…A high surface area of nanofibers provides modifications on bioactivity (e.g., increase of the cell proliferation), electroactivity, strength, etc. The applications of nanofibers cover various aspects, such as filter materials [ 33 , 34 , 35 , 36 , 37 , 38 , 39 ], electronic technology (e.g., nanoelectronics, optical sensors, battery electrode materials, and capacitors) [ 40 , 41 , 42 , 43 , 44 , 45 ], biomedical science (e.g., such as tissue engineering and drug delivery) [ 46 , 47 , 48 , 49 ], and catalyst supports [ 50 , 51 ]. There are different methods based on the top-down or bottom-up approaches to produce nanofibers, as shown in Figure 1 .…”

The Progress in the Electrolytes for Solid State Sodium‐Ion Battery

“…[46] Furthermore, the ionic conductivity of a polar β-phase PVDF gel electrolyte membrane through the electrospinning method with 1 m NaClO 4 in EC:DEC (1:1 vol%) exhibited 9.2 × 10 −4 S cm −1 . [47] Yang et al obtained a kind of PVDF-HFP-PC-NaPTAB GPE, the ion conductivity was up to 0.94 × 10 −4 S cm −1 at ambient temperature, and wide Reproduced with permission.
