Li-ion technologies are at the forefront of energy storage applications, including automotive and stationary storage, to meet global demand. TiNb2O7 (TNO) has recently garnered industrial interest from providers of Li-ion battery technologies as a new Li-ion anode material, and Nb-LLZO as a solid-state electrolyte. A continuing challenge in Li-ion battery materials is to fully understand fundamental mechanics that underpin performance. The primary mechanism in Li-ion insertion electrodes is Li+ diffusion, which enables the electrochemical lithiation and delithiation of such materials. We plan to complete a series of muSR measurements to finish preliminary studies on materials synthesised at the Kg/hr scale for commercial applications. This will allow us to establish the lithium diffusion dynamics within these materials and support other synchrotron-based analyses.
