Pseudocapacitive charge storage materials offer the opportunity to bridge the gap between high energy density battery materials and high power density electrical double layer capacitor materials through the rational design of transition metal oxide nanoscale architectures. The research reported in this paper describes the origins and development of pseudocapacitance in MoO₂. Micron-size particles of MoO₂ exhibit a reversible monoclinic to orthorhombic phase transition upon lithium insertion/deinsertion, however, this phase transformation is suppressed when using 15 nm nanocrystals of MoO₂. The nanoscale MoO₂ exhibits pseudocapacitive behavior and achieves substantially better energy storage kinetics than the corresponding bulk material. Such size-dependent electrochemical behavior is an essential feature of an extrinsic pseudocapacitor material. The high power capability of nanoscale MoO₂ is improved further by synthesizing hybrid materials in which MoO₂ nanoparticles are grown on reduced graphene oxide (RGO) scaffolds. Electrode architectures containing MoO₂-RGO hybrid materials preserve the pseudocapacitance of MoO₂ as lithium capacities of nearly 150 mAh g^–1 are obtained at a rate of 50 C.
