Nanohybridization of Keggin polyoxometalate clusters and reduced graphene oxide for lithium-ion batteries.

ABSTRACT: The nanocomposites of reduced graphene oxide (RGO) and polyoxometalates (POMs) have been considered to be effective to boost more Li⁺ to participate in intercalation/deintercalation process of lithium-ion batteries (LIBs). In this paper, a nanocomposite (PMo₁₂@RGO-AIL) with electrostatic interaction of RGO and Keggin-type [PMo₁₂O₄₀]^3- has been fabricated and characterized by XRD, XPS, SEM, and TEM. To prepare PMo₁₂@RGO-AIL, a strategy of covalent modification is developed between amino-based ionic liquid and RGO, helping to achieve the uniform dispersion of [PMo₁₂O₄₀]^3-. When the PMo₁₂@RGO-AIL was used as a cathode for LIBs, it could exhibit more excellent reversible capacity, cycl
