Li–O2 batteries

An agent for change

The rechargeable Li–O2 battery has low energy efficiency, which is mainly due to kinetic difficulties in the electrochemical oxidation of the insulating discharge product, Li2O2. Now a redox mediator, acting as an electron–hole transfer agent, has been used to promote this oxidation reaction.
