摘要
A detailed kinetic analysis is used to determine the fundamental energy storage properties and rate capabilities of TiO2 nanosheets. These materials exhibit different properties compared to anatase nano-crystals including a shift to lower redox potentials for Li+ storage and the reversible charge storage of Na+. Nanosheets are intriguing for energy storage applications due to the fact that nearly the entire surface of the material, including specific crystal facets, can be exposed to the electrolyte.
