Abstract
The first‐ever demonstration of stabilized Si/lithium–manganese‐rich full cells , capable of retaining >90% energy over early cycling and >90% capacity over more than 750 cycles at the 1C rate (100% depth‐of‐discharge), is made through the utilization of a modified ionic‐liquid electrolyte capable of forming a favorable cathode–electrolyte interface.
