Direct coherent multi-ink printing of fabric supercapacitors

Phys.org  January 29, 2021 Fiber-shaped supercapacitors are a desirable high-performance energy storage technology for wearable electronics. The traditional method for device fabrication is based on a multistep approach to construct energy devices, which can present challenges during fabrication, scalability, and durability. An international team of researchers (China, USA – University of Colorado, Carnegie Mellon University, Singapore) has developed an all-in-one coaxial fiber-shaped asymmetric supercapacitor (FASC) device using direct coherent multi-ink writing, 3-D printing technology by designing the internal structure of the coaxial needles and regulating the rheological property and feed rates of the multi-ink. The device delivered a superior areal […]

Wood to supercapacitors

Nanowerk  May 24, 2018 Researchers in China have developed an economical and sustainable method for the synthesis of ultrathin carbon nanofiber (CNF) aerogels from the wood‐based nanofibrillated cellulose aerogels via a catalytic pyrolysis process. They demonstrated that wood‐derived CNF aerogels exhibit excellent electrical conductivity, a large surface area, and potential as a binder‐free electrode material for supercapacitors. The results suggest great promise in developing new families of carbon aerogels based on the controlled pyrolysis of economical and sustainable nanostructured precursors… read more. TECHNICAL ARTICLE
