超级电容电池用多层次孔双功能炭材料

Hierarchical porous bifunctional carbon material for super capacitor battery

以酚醛树脂为碳源、碱性化合物为模板，制备了超级电容电池负极用多层次孔双功能炭（HPBC）材料，进行了TEM、SEM、氮气吸脱附、恒流充放电和循环伏安测试。制备的HPBC具有大-中-微的多层次孔结构；在LiPF6／EC＋DMC和EhNBFa／AN电解液中均有良好的电化学性能，具有Li＋嵌脱储能与双电层吸脱附储能的“双功能”特性，在0～2．0V、0．2C时的可逆比容量达289mAh／g，双电层比电容达18F／g。

Hierarchical porous bifunctional carbon （HPBC） material for super capacitor battery anode was synthesized by using phenolic resin as carbon source and basic compounds as template. The analyses of TEM, SEM, nitrogen adsorption-desorption, galvanostatic charge-discharge and cyclic voltammeter were taken. The prepared HPBC material had macro-meso-microporous poresize distribution and fine electrochemical performance in LiPF6/EC ＋ DMC and EtaNBFa/AN electrolyte,it had a high reversible specific capacity of 289 mAh/g in 0 - 2.0 V,0.2 C,along with a double-layer specific capacitance of 18 F/g.
