高温热处理石油焦的微观结构与其充放电性能的关系

The Relation Between the Microstructure and Charging-discharging Performance of the High Temperature Treated Petroleum Cokes

对两种不同的石油焦进行了高温热处理 ,采用 X射线、扫描电镜和 Raman光谱研究了经不同高温热处理温度 (TH,max)处理过的试样的结构、形貌、织构与石墨化度。采用恒电流充放电原位 XRD法和粉末微电极循环伏安法研究了试样的充放电过程 ,据此讨论了微观结构与充放电性能的关系。

Two types of petroleum coke were heated with different maximum heat treatment temperature ( T H,max ),the structure,morphology and graphitization degree of these samples were analyzed by means of XRD,SEM and Raman spectrum.The relation between their microstructure and charging discharging performance were discussed.
