研究了安莉二次电池正极材料Pf6(-)在不同碳源中的电化学插层行为。结果表明，PF6(-)的电化学插层容量随(002)晶面距离的减小而增大，即随着石墨-碳结晶度的增加而增大，且在接近理想的石墨-碳结构的碳上达到最大容量。采用高结晶度的石墨炭和稳定的碳酸亚乙酯-碳酸二甲酯电解液，成功地研制出高容量(90mAhg)和倍率特性的二次电池。(C)2007年电化学会。
Electrochemical intercalation of PF6(-) into various carbons was studied for the cathode of an Li-ion rechargeable battery. It was found that the capacity of the electrochemical intercalation of PF6(-) increases with decreasing (002) plane distance, namely, increasing the crystallinity of graphitic-carbon, and the largest capacity was achieved on the carbon with almost ideal graphiticcarbon structure. By using graphitic carbon with high crystallinity and the stable electrolyte of ethylene carbonate-dimethylene carbonate, a rechargeable battery with high capacity (90 mAh/g) and rate property was successfully demonstrated.
