Commercial battery grade nano-LTO powder was brought in contact with different electrolytes containing ether lithium or sodium as cations and PF6 -, Triflate (Tfl -) or Tetrakis-(pentafluorophenyl)-borate (Tpb -) as anions (Figure ). The longitudinal relaxation time constant T1 of bulk Li nuclei was recorded in a temperature range from -10°C to 50°C. We inverted the recorded data using Inverse Laplace Transformation (ILT) without non-negativity constrains. By this it is possible to separate relaxation processes in solid lithium conducting materials. The procedure is exemplified on pure LTO under Argon atmosphere (Figure ). The first row shows static Li NMR spectra of the sample measured at -10°C, 20°C and 50°C. The blue spectrum is the fast relaxing contribution to the overall spectrum, calculated as the sum of the relaxation distribution between 25s and 80s, and the red spectrum is the slowly relaxing contribution to the spectrum between 100s and 315s. The second row shows the spectrally resolved T1 distribution of the three measurements. The third row compares the T1 distribution of the three temperatures, integrated along the spectral dimension. It is evident that the temperature has a small but observable effect on the maximum and the distribution of the T1 relaxation. While the exact distribution may vary slightly due to the ill-posedness of the problem, the mean, the median or the width of each mode are quite robust parameters. Hence, the position of the maximum and the mean are used to analyze the effects of the solvents and temperature in the following.
