Characterization of LTO electrodes in EC-DMC 1 M LiPF6 solutions. a Two first sequential CVs from OCV to 1 V and then to 2 V, as indicated. b Frequency and resonance width changes at different overtones (shown by different colors) as functions of time during electrode cycling. The dashed red lines denote the potentials at which viscoelastic analysis has been carried out
