Lithiated LTO anodes were harvested in the glovebox from the Swagelok LTO-Li battery, where the LTO electrode was discharged at 50 mAg -1 to approximately 80 % of the maximum obtained specific capacity. The lithiated LTO electrode was afterward paired with the pristine OTQC electrode and separated with a Celgard 2320 separator, with an additional three drops of 1 M LiTFSI in a 1:1 (v/v) DOL and DME electrolyte. The obtained cell was cycled in different voltage windows corresponding to cycling of OTQC-Li battery (1.65 V -3.8 V), taking into account the voltage hysteresis of LTO material at different current densities.
