The rapid development of artificial intelligence and wearable electronics has garnered significant interests in flexible sensors with good comfort and sensing performances. A variety of materials, including gels [1], [2], films [3], [4], paper [5], [6], sponges [7], [8] and textiles [9], [10], [11], [12], have been proved effective as substrates for constructing flexible sensors.

Spatially Confined FeF3 Cathodes in N-Doped Carbon Nanotubes for Lithium Storage Herein, a N-doped carbon nanotube encapsulated FeF3 nanoparticle (FeF3@N-CNTs) composite was developed via in situ pyrolysis and gas-phase fluorination strategies. The 3D carbon constrained scaffold enhances conversion reaction kinetics and effectively suppresses significant volume changes in the FeF3 cathode during cycling.

2 Results and Discussion The crystal structure of the as-prepared material was investigated via the X-ray diffraction (XRD) patterns together with the Rietveld refinement, as shown in Figure 1a–c. Figure 1a displays XRD patterns of the NVO, NVO/rGO, and NVO-rGO membranes. It can be observed that the composition of materials is determined as the mixture of Na5V12O32 and NaV3O8 phase, among which, most of them could be well catalogued to the monoclinic structure of Na5V12O32 (JCPDS no. 24–1156).
