New strategy to prepare N-doped holey graphene for   high-volumetric supercapacitors

New strategy to prepare N-doped holey graphene for high-volumetric supercapacitors

Dong et al. have introduced a novel but effective “Bottom-up” pathway to prepare N-doped holey graphene and its derived high density carbon own high volumetric capacitances for supercapacitors. N-doped holey… Read more »

Reduced graphene oxide/polypyrrole nanotube papers for flexible all-solid-state supercapacitors with excellent rate capability and high energy density

Reduced graphene oxide/polypyrrole nanotube papers for flexible all-solid-state supercapacitors with excellent rate capability and high energy density

  In this work, we fabricated rGO/PPy nanotube (NT) papers for flexible all-solid-state supercapacitor (ASSSC) electrodes. The incorporation of rGO nanosheets could improve the cycling stability of PPy NT paper… Read more »
