  title = {High-Rate Li+ Storage Capacity of Surfactant-Templated Graphene-TiO2 Nanocomposites},
  abstract = { Graphene-TiO<sub>2</sub> nanocomposites are a promising anode material for Li-ion batteries due to their good high-rate capacity, inherent safety, and mechanical and chemical robustness. However, despite a large number of scientific reports on the material, the mechanism of the enhanced high-rate Li<sup>+</sup> storage capacity that results from the addition of graphene to TiO<sub>2</sub> {\textendash} typically attributed to improved electrical conductivity {\textendash} is still not well understood. In this work, we focus on optimizing the processing of surfactant-templated  graphene-TiO<sub>2</sub> hybrid nanocomposites. Towards this end, we examine the influence of various processing parameters, in particular the surfactant-mediated colloidal dispersion of graphene, on the material properties and electrochemical performance of graphene-TiO<sub>2</sub>. We investigate the influence of electrode mass loading on Li<sup>+</sup> storage capacity, focusing mainly on high-rate performance. Furthermore, we demonstrate an approach for estimating power loss during charge/discharge cycling, which offers a succinct method  for characterizing the high-rate performance of Li-ion battery electrodes. },
