Nanostructured Li3V2−xNix(PO4)3 (x = 0, 0.05, and 0.1) cathodes, thanks to their high rate capability and excellent cycle stability, are proposed as excellent candidates for the development of high energy and high power density Li-ion asymmetric supercapacitors.

Asymmetric Supercapacitors

We developed an asymmetric supercapacitor using NiCo2S4 nanotube arrays grown on carbon textile, achieving a high energy density (∼40.1 W h kg−1 at 451 W kg−1), a high power density (∼4725 W kg−1 at 21 W h kg−1) and excellent cyclability.
