Li–O2 batteries

An agent for change

Nature Chemistry volume 5, pages 445–447 (2013)Cite this article

Subjects

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.

One of the greatest challenges of the twenty-first century is unquestionably the conversion of energy and its storage. If the needs of modern society are to be met, while also considering environmental concerns and energy security, then breakthroughs in battery science and technology are required.
