A novel indirect charging system that uses a redox mediator was demonstrated for Li-O 2 batteries. 4-Methoxy-2,2,6,6-tetramethylpiperidinyl-1-oxyl (MeO-TEMPO) was applied as a mediator to enable the oxidation of Li 2 O 2 , even though Li 2 O 2 is electrochemically isolated. This system promotes the...

Summary:A novel indirect charging system that uses a redox mediator was demonstrated for Li-O 2 batteries. 4-Methoxy-2,2,6,6-tetramethylpiperidinyl-1-oxyl (MeO-TEMPO) was applied as a mediator to enable the oxidation of Li 2 O 2 , even though Li 2 O 2 is electrochemically isolated. This system promotes the oxidation of Li 2 O 2 without parasitic reactions attributed to electrochemical charging and reduces the charging time. We demonstrated a novel indirect charging system for Li-O 2 batteries, chemical regeneration , which reduces both charging time and capacity fade.
