The effect of addition of the redox mediator dimethylphenazine on the oxygen reaction in porous carbon electrodes for Li/O2 batteries
Vullum-Bruer, Fride; Vullum, Per Erik; Svensson, Ann Mari; Augustin, Matthias (Peer reviewed; Journal article, 2023)Secondary Li–O2 batteries are promising due to their potentially high theoretical energy density. However, both the discharge (oxygen reduction reaction, ORR) and the recharge reaction (oxygen evolution reaction, OER) are ... -
Inside the electrode: Looking at cycling products in Li/O2 batteries
Augustin, Matthias; Vullum, Per Erik; Vullum-Bruer, Fride; Svensson, Ann Mari (Journal article; Peer reviewed, 2019)This work investigates the impact of electrochemical reactions and products on discharge capacity and cycling stability with electrolytes based on two common solvents – tetraethylene glycol dimethyl ether (TEGDME) and ... -
Product formation during discharge: a combined modelling and experimental study for Li–O2 cathodes in LiTFSI/DMSO and LiTFSI/TEGDME electrolytes
Rauter, Michael Tobias; Augustin, Matthias; Spitthoff, Lena; Svensson, Ann Mari (Peer reviewed; Journal article, 2021)Li–air or Li–O2 batteries are a promising energy storage technology due to the potentially high energy density. However, significant challenges related to reversible charge/discharge of these cells need to be solved. The ... -
