A green asymmetric supercapacitor with high energy density has been developed using birnessite-type ultrathin porous MnO2 nanoflowers (UBMNFs) as positive electrode and functional mesoporous carbon nanotubes (FMCNTs) as negative electrode in 1 M Na2SO4 electrolyte. Both of the electrode materials po...
