High-efficiently doping nitrogen in kapok fiber-derived hard carbon used as anode materials for boosting rate performance of sodium-ion batteries
Lanzhou University of Technology
Abstract
A high content N-doped hard carbon is prepared through the effects of 2,6-pyridine dicarboxylic acid and zinc chloride , exhibiting an excellent rate performance due to abundant pyridine N and C=O. The engineering of plant-based precursor for nitrogen doping has become one of the most promising strategies to enhance rate capability of hard carbon materials for sodium-ion batteries; however, the poor rate performance is mainly caused by lack of pyridine nitrogen, which often tends to escape because of high temperature in preparation process of hard carbon. In this paper, a high-rate kapok fiber-derived hard carbon is fabricated by cross-linking carboxyl group in 2,6-pyridinedicarboxylic acid with the exposed…
