Title: The electrochemical behaviour of TTF in Li–O 2 batteries using a TEGDME-based electrolyte

Abstract

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