摘要：

Application of water-based supercapacitor is largely limited by the disadvantages regarding electrolyte leakage and electrolyte corrosion. To address these issues, herein, a quasi-solid-state supercapacitor based on carbon felt (CF) electrode with PVA-KI/H2SO4 mixed gel electrolyte has been fabricated and an stable uniform acetalized polyvinyl alcohol (UAPVA) membrane in acidic condition has been reported for the first time. Given the excellent chemical and mechanical properties, the UAPVA membrane can facilitate I- transportation and still be restored to its original shape after stretching, b...
