为了提高储能密度和循环稳定性，提出了一种基于介孔Bi2MoO6准纳米球(MBiN)的活性碳布(ACC)杂化电极的柔性全固态超级电容器(FSCS)。利用共价键作用，通过原位生长的方法将MBI直接固定在ACC表面，其理想的孔径为6.46 nm，大的比表面积为233.31×10-2g−-1，小的平均粒径为~40×10-6 nm。基于MBI N/ACC柔性电极的优化超级电容器表现出超高的质量电容(345.0 F g−1，1：A g−1)和优异的倍率性能(181.2 F g−1，5 A g−1)，并在10000次GCD循环后保持了90.2%的容量。值得注意的是，它的能量密度高达110.4瓦时·公斤−1，功率密度为1429.6瓦·公斤−1。此外，ACC基板使该器件在各种弯曲状态下具有优异的强度和灵活性。
A typical flexible all-solid-state supercapacitor (FSCs) is proposed based on mesoporous Bi2MoO6quasi-nanospheres (MBiN) on activated carbon cloth (ACC) hybrid electrode for improving the energy storage density and cyclic stability in this work. Specifically, MBiN is anchored directly on the surface of ACC via an in situ growth routine by using covalent bonding interactions, which shows an ideal pore diameter of 6.46 nm, a large specific area of 233.31 m2g−1, and a small average particle size of ~40 nm. Benefit from MBiN and ACC features, the optimized supercapacitor based on MBiN/ACC flexible electrodes displays an ultrahigh mass capacitance (345.0 F g−1at 1 A g−1) and an excellent rate performance (181.2 F g−1at 5 A g−1) coupled with a satisfactory capacitance retention of 90.2% after 10000 GCD cycles. Notably, its energy density values up to 110.4 Wh·kg−1at a power density of 1429.6 W kg−1. Furthermore, ACC substrate endows the device with the excellent strength and flexibility under various bending states.
