Abstract
HighlightsThe conductive silver-plated nylon yarns fully fit the demand for wearable supercapacitor skeleton, owing to the advantages of high conductivity and flexibility.The computerized programming embroidering technique was firstly applied for realizing standardized batch processing of the flexible supercapacitor skeleton in various patterns.Cobalt phosphides were properly electrodeposited on the conductive embroidery as the pseudocapacitive materials, providing remarkable electrochemical performance.
Highlights
Wearable energy storage devices are receiving great attention and popularity for the growing demands from the modern portable electronics and smart textiles [1,2,3,4]
The schematic diagram of the CoP@Ni nanothorn arrays (NTAs)@SE fabrication is demonstrated in Fig. 1a–c, where an interdigitally patterned embroidery was successfully developed via the computerized programming
The target patterns were designed and drawn by the soft kit, and a piece of the silver-plated nylon yarns (SPNYs) was threaded into the embroidery machine for stitching the embroidery, with a piece of the common cotton fabric stuck on the workbench as the substrate
Summary
Wearable energy storage devices are receiving great attention and popularity for the growing demands from the modern portable electronics and smart textiles [1,2,3,4]. A CoP nanowires-based carbon cloth displayed remarkable negative capacitive behavior in the neutral LiCl/PVA electrolyte, but it dissolved gradually due to the side reactions with Cl− system [25]. In this regard, it is highly expected to further explore the potential of Ni/ Co-based phosphides as the electrode material of SCs. As a matter of fact, for flexible and wearable devices, the typical textile processing techniques [26,27,28,29,30], such as knitting, weaving, and embroidering, are rarely reported for integrating with the applications. The computerized programming successfully embroidered a monogrammed conductive pattern on the laboratory gown, demonstrating a promising prospect in large-scale production of the wearable energy storage devices
