Preparation and application of cellulose gel in flexible supercapacitors

Flexible supercapacitor is an important kind of energy storage devices to power the flexible electronics because of its excellent capacitive performance, fast charging/discharging ability and long-term stability. Cellulose gel has become an ideal material as electrode or separator in flexible supercapacitors due to its hydrophilicity, high porosity, large specific surface area, low density and flexibility. This review first describes the...
