Novel electrospun separator-electrolyte based on PVA-K2CO3-SiO2-cellulose nanofiber for application in flexible energy storage devices

Electrospun fiber membrane as a separator-electrolyte have been prepared in this study using electrospinning process from cellulose acetate, PVA, K2CO3, and SiO2 with different concentrations. Five different concentration were prepared (14�22 wt) using mixture of dimethyl sulfoxide and acetone in...
