Microscopic Li self-diffusion parameters in the lithiated anode material Li4 + xTi5O12 (0 < or = x < or = 3) measured by 7Li solid state NMR.
The microscopic Li diffusion parameters in the lithiated spinel Li4 + xTi5O12, which is on its way to become a commercially used anode material in Li ion batteries, are probed for the first time via nuclear magnetic resonance spectroscopy.
