Abstract

Abstract : In article number 2001830, Guk‐Tae Kim, Stefano Passerini and co‐workers highlight the benefits of employing ionic‐liquid electrolytes (ILE) in combination with cobalt‐free, lithium‐rich layered oxide positive electrodes. The ILE dramatically reduces the capacity and voltage fading of Li1.2 Ni0.2 Mn0.6 O2 by suppressing the structural decay of the Li1.2 Ni0.2 Mn0.6 O2 cathode enabling long‐term stable cycling of lithium metal batteries.
