The charge storage mechanism of lithium-ion batteries, as well as of novel cell chemistries beyond lithium, is based on electrochemical ion intercalation. The process involves the reversible storage of ions in a solid-state host electrode material that is typically undergoing small structural changes. Solid-state diffusion of the ions within the host lattice, as well as associated volumetric and/or crystallographic phase changes of the host itself, can limit the kinetics of the intercalation reaction. To realize high power charge storage processes, strategies to mitigate such limitations are being developed from an electrode perspective across length scales, from the macroscopic particle size scale down to the microscopic atomic arrangement within the host. Vanadium oxides are widely established as host materials for ion intercalation reactions. The bilayered V2O5 phase (δ-V2O5) is particularly versatile due to its ability to host a variety of cations, such as lithium, sodium, manganese, or zinc. It can further be synthesized by several wet-chemical and hydrothermal methods, yielding a wide variety of attainable morphologies. Thus, the material is suitable as a model system to explore electrochemical intercalation properties as a function of the host material structure and particularly its interlayer spacing.
