Improved cycle efficiency of lithium metal electrodes in Li-O₂ batteries by a two-dimensionally ordered nanoporous separator

We demonstrate a facile but very effective approach to improve the cycling efficiency of metallic lithium electrodes by controlling the pore morphology of separators. We employed anodized porous alumina as the model nanoporous separator and demonstrated the improvement of cycle efficiency of lithium electrodes in lithium-oxygen cells. 2014 This journal is © the Partner Organisations.
