摘要

煤炭因具有结构复杂性而导致其结构演变不可控，这对高性能煤基硬炭材料的设计与制备产生了阻碍。以新疆不粘煤为原料，分别研究了N-甲基吡咯烷酮（NMP）和等体积比NMP-CS2作为萃取剂对煤基硬炭材料结构和储钠性能的影响。结果表明，以NMP作为萃取剂所得样品（HC-NMP）表面的C==O基团含量最高，这有利于在预氧化过程中构建交联结构。HC-NMP具有较大的碳层间距和较多的无序碳结构，有利于Na

存储。在20 mA/g下，HC-NMP的可逆比容量为281.1 mAh/g，第一圈库伦效率为84.1%。在100 mA/g下循环200次，HC-NMP的可逆比容量为240.3 mAh/g。

Abstract

Due to the structural complexity of coal

its structural evolution is uncontrollable

which hinders the design and preparation of high-performance coal-based hard carbon materials. The effects of N-methylpyrrolidone (NMP) and NMP-CS

(equal volume ratio) as extractants on structures and sodium storage properties of coal-based hard carbon materials were studied using Xinjiang nonstick coal as the raw material. The results show that the content of C==O groups on surface of the samples

(HC-NMP) obtained with NMP as extractant is the highest

which is conducive to the construction of cross-linked structures during the preoxidation process. HC-NMP has large carbon layer distance and more disordered carbon structure

which are conducive to Na

storage. At 20 mA/g

the reversible specific capacity of HC-NMP is 281.1 mAh/g

and the first cycle Coulomb efficiency is 84.1%. After 200 cycles at 100 mA/g

the reversible specific capacity of HC-NMP is 240.3 mAh/g.
