Nitrogen-doped lignin based carbon microspheres as anode material for high performance sodium ion batteries

Lignin-Based Materials for Sustainable Rechargeable Batteries

“…The surface functionalities (such as P and N) can improve the electrochemical performance of carbons [95][96][97]. Nitrogen-doped lignin-based carbon (sample termed "n-doped Lignin") can be obtained by carbonization with a 3-aminophenol (nitrogen source) [98]. N-doped lignin has a small graphitic region, significant micro-, meso-, and macro pores, and enlarged interlayer space.…”

From residue to resource: new insights into the synthesis of functionalized lignin micro/nanospheres by self-assembly technology for waste resource utilization

“…However, the control group without hydrothermal treatment did not form microspheres, which verified the feasibility and applicability of the hydrothermal extraction of microspheres. 48,49 Although the natural acetylated lignin microspheres obtained by hydrothermal acid extraction have no large energy consumption, 48 we still need to carry out further research to verify the feasibility of this method considering the differences in lignin raw materials and lignin types. Therefore, after exploring the preparation methods of nanospheres, both acetylated and unmodified LMNPs have better prospects in terms of morphology, particle size and surface uniformity.…”

A review on the effects of doping elements on the properties and applications of lignin-based carbon materials

“…Fan et al 41 synthesised nitrogen-doped lignin-based carbon microspheres using a hydrothermal reaction using 3-aminophenol as the main nitrogen source. The prepared carbon microspheres had good spherical morphology and contained many active sites, ultra-microporous (less than 0.7 nm) structures and large layer spacing.…”
