High surface area, hierarchical porous carbon materials were obtained by carbonization and activation process of the loofah sponge. The porous carbon materials with good conductivity exhibit high energy density and power density.
N, O and P co-doped honeycomb-like hierarchical porous carbon (N-P-HHPC-3) derived from Sophora japonica displays an ultrahigh energy density (80.8 W h kg−1 at 1500 W kg−1) and outstanding long-term stability.
N,O co-doped 3D HPC derived from soybean dregs was prepared by a one-step method and displays an amazingly high energy density of 22 W h kg−1 (450 W kg−1) using 1 M Na2SO4 solution.
Benzoquinone with high theoretical capacity is anchored on N-plasma engraved porous carbon as a desirable cathode for rechargeable aqueous Zn-ion batteries. Such batteries display tremendous potential in large-scale energy storage applications.
