Zinc ion trapping in a cellulose hydrogel as a solid electrolyte for a safe and flexible supercapacitor
A flexible zinc-ion hybrid supercapacitor (ZHS) was constructed using a solid-state cellulose hydrogel electrolyte containing a high concentration of ZnCl 2 . This biodegradable cellulose hydrogel electrolyte can afford a wide electrochemical potential window and excellent ionic conductivity, result...
