3D braided yarns to create electrochemical cells

摘要: Abstract The demands for new configurations of electrochemical cells continue to grow and novel approaches are being enabled by the advent electromaterials fabrication strategies. Wearable energy storage devices that can be seamlessly integrated into garments a critical component wearable electronics genre. Recently, flexible yarn supercapacitors have attracted significant attention due their ability fabrics, or stitched existing textiles. Large-scale production using conventional manufacturing processes, however, is still challenge. Here, we introduce use braiding technology achieve predetermined arrangement fibre electrodes, basis mass protocol produce specific cells: supercapacitors. resultant show high capacitance 1.71 mF cm − 1 . structure highly with 25% loss recorded after 1000 bending cycles.
