Preparation and properties of flexible high capacity composite fabric electrode

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 electro-nic devices. By adjusting the deposition time of methanol phase method, cobalt based metal organic framework (Co-MOF) 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 22.6 μA·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 perfor-mance 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.
