Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>High Energy and a Long Life—An Al₂O₃ coating for Li‐ion Battery Electrodes:</bold> The cover image demonstrates ultrathin Al₂O₃ coating by using atomic layer deposition on the high‐voltage cathode LiNi_0.5Mn_1.5O₄ for high‐energy‐density, stable Li‐ion batteries. The ultrathin coating can protect the LiNi_0.5Mn_1.5O₄ cathode from undesired reactions during high‐voltage cycling. At the same time, the electron path can be maintained and the extra weight added to the electrode is negligible. As described in the Full Paper by Prof. Chongwu Zhou and colleagues at the University of Southern California on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 159, </ext-link> superior performance can be achieved from the high‐voltage cathode of this battery configuration in both room‐temperature and high‐temperature tests.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr3m01s" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
