摘要: Abstract One of the most challenging issues in developing electrochemical flow capacitor (EFC) technology is design and synthesis active electrode materials with high energy density long cycle life. However, practical cases, ability obtained currently cannot meet need. In this work, we propose a new material, nitrogen-doped carbon spheres (NCSs), as flowable electrodes for EFC application. The NCSs were prepared via one-pot hydrothermal presence resorcinol/formaldehyde precursors melamine nitrogen precursor, followed by carbonization at various temperatures. results experiments demonstrate that 800 °C exhibit 13.5 Wh kg −1 an excellent ability, indicating superiority
