摘要：

柔性全固态超级电容器(FASS)是可穿戴电子设备以及电力设备的能源供应,石墨烯纳米片具有独特的二维结构,较强的机械性能和优异的导电性,在纸片状柔性电极中应用广泛.基于简单石墨烯纳米片的FASS的双层电容性能的基本特征限制了其性能的提高和实际应用.研究了一种基于超大型石墨烯纳米片和超薄氮化硼(BN)纳米片的FASS,通过真空辅助过滤组装独立式超大型石墨烯纳米片/BN纳米片复合纸电极.新型超大型石墨烯纳米片/ BN纳米片纸的特有结构可以有效整合假电容BN纳米片和导电石墨烯的优点,从而在FASS中表现出出色的电化学性能.5000 次充放电后,FASS的最高面积比电容达到325.4 mF/cm²,并具有约86.2%的高容量保持率,且在85.7 W/kg的功率密度下具有22.8 W·h/kg (1 W·h=3.6 kJ)的高能量密度.

Abstract:

Flexible all-solid-state supercapacitors (FASS) are energy supplies for wearable electronic devices and power devices. Graphene nanosheets have unique two-dimensional (2D) structures, strong mechanical properties, and an excellent electrical conductivity, which are widely used in paper-like flexible electrodes. The essential feature of the double-layer electric performance for the simple graphene nanosheet-based FASS restricts the improvement of their capacitive performance and practical applications. FASS based on the ultralarge graphene nanosheets and the ultrathin boron nitride (BN) nanosheets are investigated. The nacre-like structures could efficiently integrate both merits of pseudocapacitive BN nanoflakes and conducting graphene, thereby exhibiting an excellent electrochemical performance in FASS. After 5000 charge-discharge cycles, the highest areal specific capacitance of FASS reaches 325.4 mF/cm², with a high capacity retention rate of about 86.2% and a high energy density of 22.8 W·h/kg (1 W·h=3.6 kJ) at a power density of 85.7 W/kg.

Key words: flexible all-solid-state supercapacitors (FASS), graphene, boron nitride (BN)
