As potential alternatives to lithium-ion batteries in grid energy storage application, sodium-ion batteries (SIBs) have attracted tremendous attention. Absence of high-performance anode material remains a challenge to commercialize SIBs. Herein, a SnSbSx/porous carbon nanofiber (SnSbSx/PCNF) composite with superior performance is successfully prepared via electrospinning, followed by a sulfuration...
Non-metallic fractions of FR-3 type waste printed circuit boards were pyrolyzed at high temperatures. The resultant char at 600°C was used to prepare activated carbons by physical and chemical activation. The influence of pyrolysis temperature on char yields, and activation conditions on the burn-off and porous properties of the activated carbons were investigated. Results show that char yields decrease...
Si/C composite nanofibers were prepared by electrospinning and carbonization using polyacrylonitrile (PAN) as the spinning medium and carbon precursor. The nanofibers were used as lithium-ion battery anodes to combine the advantages of carbon (long cycle life) and silicon (high storage capacity) materials. The effects of Si particle size, Si content, and carbonization temperature on the structure...
A series of activated carbon (AC) supported nickel oxide (NiO) catalysts were prepared by aqueous reduction preparation methods with nickel nitrate as a precursor. The effects of preparation procedure and reducing agent on catalyst structure and catalytic property were investigated. Based on the information obtained from physico-chemical characterizations and sorbitol dehydration performances, preparation...
