Problems solved by technology

Although this study successfully prepared biomass-derived carbon materials, the specific capacitance of the materials is low, which still cannot meet the application requirements of energy storage devices (S.Sankar, Abu Talha Aqueel Ahmed, Akbar I.Inamdar, HyunsikIm, Young Bin Im, Youngmin Lee, Deuk Young Kim, Sejoon Lee. Biomass-derived ultrathin mesoporous graphitic carbon nanoflakes as stable electrode material for high-performance supercapacitors, Materials and Design, 2019, 169, 107688)
[0004] From the above analysis, it can be seen that although carbon materials have high cycle stability as supercapacitor electrode materials, they provide low electric double layer capacitance, resulting in low energy density for assembled energy storage devices.
