(a) is the cyclic voltammetry (CV) profile for the hierarchical Co3O4 nanoparticles@graphitized carbon peapoded fibers array on Ti foil, verifying the thermodynamic stability in electrochemical cycling. (b) is the galvanostatic measurement curve at a current density of 100 mA/g. (c) is the long time and rate capability test on the hierarchical Co3O4 nanoparticles@graphitized carbon peapoded fibers array on Ti foil and (d) is the corresponding coulombic efficiency.
