The electrochemical behaviour of TTF in Li-O sub(2) batteries using a TEGDME-based electrolyte

The electrochemical behaviour of tetrathiafulvalene (TTF), a redox mediator proposed to improve the recharge kinetics of Li-O sub(2) batteries, was investigated viasynchrotron and lab X-ray diffraction. Using the LiFePO sub(4) anode, TTF causes chemical lithiation of the FePO sub(4) phase. TTF is al...

Zusammenfassung:The electrochemical behaviour of tetrathiafulvalene (TTF), a redox mediator proposed to improve the recharge kinetics of Li-O sub(2) batteries, was investigated viasynchrotron and lab X-ray diffraction. Using the LiFePO sub(4) anode, TTF causes chemical lithiation of the FePO sub(4) phase. TTF is also found to be unstable during discharge/charge cycles.
