Characteristics of mechanochemically prepared host-guest hybrid nanocomposites of vanadium oxide and conducting polymers

▶ Two-component nanocomposites composed of conducting polymers and vanadium oxide are prepared via a single-step, solvent-free synthesis. ▶ The nanocomposites have a guest-host structure, with the conducting polymer located in the interlayer space of the inorganic nanoparticles. ▶ The nanocomposites retain their capacity above 200 mAh g−1 over one hundred full charge-discharge cycles. ▶ Stable cycling at a current of ∼0.2 A g−1 demonstrates the stability of the nanocomposites' structure.
