Electrochemical materials are essential for advancing the energy transition, promoting circularity, and supporting a sustainable global economy. Our research spans from fundamental science to device applications, with a focus on next-generation energy storage and critical materials, including "beyond lithium" technologies.
Highlights
Single-crystal XRD mapping of lithium-ion diffusion in pre-intercalated β-NaxV2O5 and β-KxV2O5.
Na- and K-ion intercalation ‘props open’ the one-dimensional tunnel, reduces electrostatic repulsions between inserted Li ions and entirely modifies diffusion pathways, enabling orders of magnitude higher Li-ion diffusivities and accessing higher capacities.
Particle size- and geometry-dependent modification of metastable phase regimes and electrode tortuosity are key design principles for realizing the promise of intercalation cathodes.
