A new environmentally friendly gel polymer electrolyte based on cotton-PVA composited membrane for alkaline supercapacitors with increased operating voltage

A novel aqueous alkaline gel polymer electrolyte (GPE) was obtained by combining cotton with PVA, offering a wide operating electrochemical window (1.6 V) for aqueous supercapacitors (SCs). The effects achieved can be explained that the free water is limited inside GPE by strong hydrogen bonds, and...
