Multifunction web-like polymeric network bacterial cellulose derived from SCOBY as both electrodes and electrolytes for pliable and low-cost supercapacitor

In this work, bacterial cellulose (BC)-based polymer derived from a symbiotic culture of bacteria and yeast (SCOBY) are optimized as both electrodes and electrolytes to fabricate a flexible and free-standing supercapacitor. BC is a multifunction and versatile polymer. Montmorillonite (MMT) and sodiu...
