▎ 摘　　要

NOVELTY - Graphene-doped manganese oxide carbon cloth-based flexible composite electrode preparation involves adding 0.1~5.0 mg mL1 graphene to aqueous solution of 0.02-1.0 mg mL1 dispersant graphene water dispersant (TNRDIS), and ultrasonically dispersing for 40-80 minutes to obtain a mixed solution of graphene water dispersion and 0.1~0.5 molL1 manganese sulfate solution as a brush plating solution. USE - Method for preparing the graphene-doped manganese oxide carbon cloth-based flexible composite electrode for folding equipment, wearable sensors, aerospace and other fields. ADVANTAGE - The method prepares the graphene-doped manganese oxide carbon cloth-based flexible composite electrode in a simple, cost-effective and eco-friendly manner with high preparation efficiency, high bonding strength with matrix, excellent mechanical properties, high energy density, low internal resistance and high specific capacitance.
