Tailoring Core-Spun Yarns of Biomass Nanofibrils Assembled via Wet Twisting for Energy Storage and Electrochromism
To enhance the bonding strength between the active material and the core yarn current collector through nano-entanglement, bacterial cellulose/carbon nanotube (BC/CNT) nanofiber yarns were developed using in situ cultivation and wet twisting. This method utilizes the large specific surface area and abundant active functional groups of BC-based nanofibers. Subsequently, V2O5/BC/CNT composite yarn electrodes were fabricated, exhibiting a core-sheath structure with excellent conformal characteristics. The influence of ultrasound duration on the conductivity and electrochromic performance of composite yarns was investigated. The initial discharge-specific capacity was recorded as 105.3 mAh/g, with a capacity retention rate of 60.2% after 100 cycles. The composite yarn exhibited 100 reversible transitions between yellow and blue, with reduction and oxidation response times of 2.35 s and 3.3 s, respectively. The modulation amplitude at 532 nm during the initial cycle was 20.31%, and after 100 cycles, the modulation amplitude retention rate remained at 68%.
