以棉花为炭前驱体,KOH为活化剂,采用简单、高效的炭化方法,在不添加任何模板剂的情况下制备了中空管状活性炭。活化时间在0 ~ 90 min范围内对样品的微观形貌无明显影响,但对样品的比表面积和电化学性能有较大影响。结果表明,在1 mol/L H2SO 4中,电流密度为0.2 A/g时,活化60 min的样品(HTAC-60)具有较高的比表面积(2600 m2/g)、孔容(1.52 cm 3/g)和比电容(483 F/g)。此外,HTAC-60在1 mol/LH 2SO 4中,在0 ~ 1.0V电压范围内,当功率密度为200或1000 W/kg时,其能量密度分别为67.1和37.2W·h·kg-1,循环稳定性良好(5000次循环后仅损失12.2%)。结果表明,棉花是一种潜在的低成本、高性能双电层电容器活性炭电极材料的原料。
Hollow tube-like activated carbon(HTAC) was fabricated by a simple and efficient carbonization method with cotton as carbon precursor activated by KOH without any template. The activation time from 0 to 90 min showed no significant effect on the micro-morphology, but greatly influenced the specific surface area and electrochemical performance. In the end, it was found that the sample activated for 60 min(HTAC-60) has a higher specific surface area of 2600 m2/g, a larger pore volume of 1.52 cm3/g and a greater specific capacitance of 483 F/g at a current density of 0.2 A/g in 1 mol/L H2SO4. Moreover, the sample HTAC-60 shows excellent cycle stability(only 12.2% loss after 5000 cycles) and a high energy density of 67.1 or 37.2 W·h·kg–1at a power density of 200 or 1000 W/kg, respectively, operated in a voltage range of 0—1.0 V in 1 mol/L H2SO4. The results indicate that cotton can potentially be used as a raw material for producing low cost and high performance activated carbon electrode materials for electric double layer capacitor.
