Intercalation and delamination behavior of Ti3C2Txand MnO2/Ti3C2Tx/RGO flexible fibers with high volumetric capacitance

The intercalation and delamination processes of Ti₃C₂Txwere systematically investigated. A MnO₂/Ti₃C₂Tx/RGO fiber with the largest volumetric capacitance in neutral electrolyte was firstly prepared by using a wet-spinning method, and the assembled symmetric fiber supercapacitor with superior flexibility and volumetric energy density.
