摘要 采用原位X射线衍射技术 ,研究了经 2 2 5 0℃高温热处理的石油焦在 1mol/LLiClO4 +EC/DEC( 1∶1)和在 1mol/LLiClO4 +PC/DME( 1∶1)两种电解液中的嵌锂过程 ,结果表明 :在 1mol/LLiClO4 +EC/DEC( 1∶1)电解液中的嵌入物为锂离子 ,在 1mol/LLiClO4 +PC/DME( 1∶1)电解液中的嵌入物主要为溶剂化锂离子。 The intercalation process of high temperature(2 250℃)treated petroleum coke in the electrolytes 1mol/L LiClO 4+EC/DEC(1∶1)and 1mol/L LiClO 4+PC/DME(1∶1)were investigated by in situ XRD.The results showed that the intercalants in 1mol/L LiClO 4+EC/DEC(1∶1)were lithium ions and the intercalants in 1mol/L LiClO 4+PC/DME(1∶1)were mainly the solvated lithium ions.
