Ultralong lifespan of SuperRedox Capacitor using Ti-doped Li3V2(PO4)3 cathode with suppressed vanadium dissolution

The substitution of Ti 4+ into LVP increased the electron density of the V–O bonds and modified the LVP surface morphology, resulting in suppressed vanadium dissolution and longer cyclability over 10 000 cycles for LVP cathode-based full cells.
