Effect of polymer and ceramic morphology on the material and electrochemical properties of electrospun PAN/polymer derived ceramic composite nanofiber membranes for lithium ion battery separators

High performance of boehmite/polyacrylonitrile composite nanofiber membrane for polymer lithium-ion battery

“…In the XRD pattern of pure PAN nanober mat, the relatively sharp peak at 17 represents the crystalline part of PAN and a broad peak near 26 indicates the amorphous region of PAN nanober. 39 The same peaks can also be seen in the XRD patterns of different BM/PAN membranes. With the increasing introduction of BM, the peaks at 17 become broader suggesting that the crystalline structure was disrupted and the amorphous region was increased.…”

“…It demonstrates that the addition of BM into the PAN nanobers has a relatively higher decomposition temperature compared with the pure PAN nanobers. The inclusion of ceramic particles can improve the thermal stability of the polymer matrix, also conrmed by the studies of Smith et al 39 and Ji et al 41 However, there is a decrease in the exothermic peak centered at 301.5 C when the content of BM was up to 40 wt%. This may be ascribed to the decrease in air permeability.…”

Fabrication and characterization of silicon oxycarbide fibre-matsviaelectrospinning for high temperature applications

“…A limited amount of research has demonstrated the electrospinning of SiOC, [13][14][15] SiOCN, [16][17][18] SiCN, or SiBCN 19 bres via PDCs. These bres are usually synthesized from a mixture of linear polysiloxane (or polysilazane) and linear organic polymer, such as polyacrylonitrile or polyvinylpyrrolidone (PVP).…”

“…Research has also shown further implementations of electrospun bre mats for aerogel growth, 20 nanowire growth, 14,19 and electrochemical applications. 15,17 In the previous studies, pyrolyzed ceramic bre surface and cross-section features were well determined with via high resolution scanning electron microscopy (SEM) or transmission electron microscope (TEM) techniques; chemical compositions were also reported by various analysis. However, characterizations of as-spun raw bre mats and crosslinked bre mats were oen ignored.…”

A Review on Inorganic Nanoparticles Modified Composite Membranes for Lithium-Ion Batteries: Recent Progress and Prospects

“…Smith, S.A. et al [119] made a non-woven ceramic fibrous mat by electrospinning the silica precursor (TEOS). The electrospinning solution contained TEOS, DMF and PAN polymers and an organopolysilazane (OPSZ) precursor.…”
