One OTQC electrode was discharged with 20 mAg -1 down to 1.65 V and the voltage was held for 12 h. Disassembly was performed in an inert atmosphere (no washing in between). The discharged electrode was paired with a pristine OTQC electrode. One Celgard 2320 was used as a separator, with an additional three drops of 1 M LiTFSI in 1:1 (v/v) DOL and DME electrolyte. The cell was cycled at 20 mAg -1 for 5 cycles first and then subjected to high current charging/discharging.
