摘　　要：随着科学技术的飞速发展,各种可穿戴智能电子设备随之兴起。这些电子设备对化学电源的性能提出了更高要求,如安全高效且柔性的电化学储能装置。目前,大量的研究致力于柔性储能器件,以满足各种可穿戴智能电子设备供能的需求。本文通过调控甲醇相法的沉积时间,将具有高比表面、高孔隙率的钴基金属有机框架(Co-MOF)和镍钴双氢氧化物(NiCo DH)巧妙地结合在镀镍织物(NF)上,制备出了高性能的柔性复合电极。该电极具有高比容量(22.6µA·h·cm^(−2)(323 mA·h·g^(−1)))、优异的循环性能(2000次充放电后容量保持率为56%)及良好的倍率性能(电流增大50倍容量保持率为60%),并且该电极拥有优异的柔韧性,经过多次弯折,该电极的电性能几乎没有大的变化,能够满足服装的各类变形。因此,本文为可穿戴电子设备的能源供应提高了一条新的思路,在智能可穿戴领域有着广阔的前景。With the rapid development of science and technology,a variety of wearable intelligent electronic devices rised.These electronic devices put forward higher requirements for the performance of chemical power supply,such as safe,efficient and flexible electrochemical energy storage devices.At present,a lot of research was devoted to flexible energy storage devices to meet the energy supply needs of various wearable intelligent electronic devices.By adjusting the deposition time of methanol phase method,cobalt based metal organic framework(CoMOF)and nickel cobalt double hydroxide(NiCo DH)with high specific surface and high porosity were cleverly combined on nickel fabric(NF)to prepare high-performance flexible composite electrode.The electrode has a high specific capacity of 22.6µA·h·cm^(−2)(323 mA·h·g^(−1)),excellent cycle performance(the capacity retention rate is 56%after 2000 times of charge and discharge)and good rate performance(the current increases by 50 times,and the capacity retention rate is 60%),and the electrode has excellent flexibility.After many bends,the electrical performance of the electrode almost does not change greatly,which can meet all kinds of deformation of clothing.Therefore,this research improves a new idea for the energy supply of wearable electronic devices,and has broad prospects in the field of intelligent wearable.
