报告摘要：
More ion dynamics in additional redox reactions between the electrolyte and active materials could significantly improves the capacitance in supercapacitors. In out previous work, nano-sized, tunnel-structured Ti-doped Na4Mn9O18 nanoparticles (TNMO-NPs) were synthesized by a facile and high-production method of the solid-state reaction with a high-energy ball-milling process. As electrode materials applied in the supercapacitors, the as-synthesized TNMO-NPs exhibit a high energy density and superior stability. Recently, By simple dynamic regulation in synthesis process, a novel Zn-Co-Ni triple oxide material with core-shell structure has been successfully synthesized by one-step method. Benefits from its unique structure, the as packaged asymmetric supercapacitor exhibit satisfactory capacitance performance. All those results confirmed that the active materials with unique morphologies could provide more active sites composed to the electrolyte, and the tunnel lattice structures could act as an stable frame to storage the ions.
