Designing synthesis of porous biomass carbon from wheat straw and the functionalizing application in flexible, all-solid-state supercapacitors

Porous biomass carbon materials were successfully synthesized from wheat straw by a citric-acid-crosslinking and KOH-activating method. Structural characterization results indicate that the as-obtained biomass carbon materials have hierarchical porous structure and high specific surface area. Electrochemical test demonstrates that the porous biomass carbon materials from wheat straw have the optimal super-capacitive properties when the quality...
