Cotton derived porous carbon via an MgO template method for high performance lithium ion battery anodes

“…Table 1 shows a comparison of the performance of the cotton-derived porous carbon with the state-of-the-art carbon materials, including the sweet potato-derived carbon nanoparticles 37 , porous carbon nanofiber webs derived from bacterial cellulose 20 , porous carbon nanofibers/nanosheets hybrid from cornstalk waste 4 , N-rich porous carbon derived from ox horns 5 , microsized porous carbon spheres from corn starch 26 , electrospun carbon nanofibers 19,21 , pseudographite from banana peels 39 , carbon fibers from bamboo chopsticks 40 , and N-rich porous carbon spheres by SiO 2 template method 34 .…”

Novel interlayer made from Fe3C/carbon nanofiber webs for high performance lithium–sulfur batteries

“…The materials and the process employed were essentially similar to our recent studies [19,20]. Typically, 1.0 g polyacrylonitrile (PAN) (Mw=150,000, Aldrich) was dissolved in 20 ml N-dimethylformamide (DMF) and the solution was vigorously stirred on a hot plate at 80 ℃ for 3 h. 1.5 g Iron (Ⅲ) acetylacetonate was added to the solution as the precursor for Fe 3 C, which was kept stirring overnight.…”

Electrospun carbon-based nanostructured electrodes for advanced energy storage – A review

“…The prepared porous CNFs show enhanced capacities ranging from 533 to 556 mAh g -1 as compared with non-porous counterparts. To address the issue of difficult control of pore number and diameter in these approaches, an interesting method based on a combination of transition metal-based template, such as Ni or Fe and electrospinning, has been developed [15,91]. In-situ formed transition metal nanoparticle through decomposition of the transition metal precursor can turn the amorphous carbon on their surface into graphitic carbon, producing transition metal nanoparticles encapsulated in graphitic carbon nanospheres in electrospun CNFs.…”
