Nitrogen and phosphorus co-doped mesoporous carbon nanosheets derived from bagasse for lithium-ion batteries
2021
Abstract N,P co-doped bagasse-based sheet-like mesoporous carbon (NP-BC) for lithium-ion battery anode material was prepared using bagasse and NH4H2PO4 as raw material. Compared with primary bagasse carbon (BC), the specific surface area and the lattice spacing of the NP-BC increased from 1307.21 to 2118.59m2/g and from 0.34 to 0.385nm, respectively. The first discharge specific capacity also increased from 1186.59 to 2347.56mAh/g at 0.05A/g, and the reversible capacity increased more than twice.
