N-doped three-dimensional porous carbon materials derived from bagasse biomass as an anode material for K-ion batteries

N-doped pinecone-based carbon with a hierarchical porous pie-like structure: a long-cycle-life anode material for potassium-ion batteries

“…Nitrogen doping seriously distorts adjacent short-distance lattices, expanding the interlayer distance; 33 this can favor the insertion of K + . 17,33,42–46…”

Insight into a Nitrogen-Doping Mechanism in a Hard-Carbon-Microsphere Anode Material for the Long-Term Cycling of Potassium-Ion Batteries

“…Nitrogen-doping is one of the most popular doping strategies, which can not only provide additional active defects in hard carbon, but also improve conductivity by tuning the intrinsic electronic state [24]. Urea is used as a dopant, and Deng et al [25] designed an N-doped three-dimensional biomassderived porous carbon from bagasse. The experimental results show that the introduction of nitrogen not only promotes the change in morphology, but also accelerates the transport of potassium-ions and electrons.…”

Na3V2(PO4)2F3@bagasse carbon as cathode material for lithium/sodium hybrid ion battery

“…In recent years, the use of bagasse has been applied in the preparation of batteries. Deng et al 24 prepared N-doped carbon derived from bagasse and applied it to a potassium ion battery, which still had a capacity of 100.4 mA h g −1 after 400 cycles. Zheng et al 25 used N and P co-doped mesoporous carbon nanosheets prepared from bagasse in lithium ion batteries, and obtain a first discharge specific capacity of 2347.56 mA h g −1 at 0.05 A g −1 .…”
