Robust interphase derived from a dual-cation ionic liquid electrolyte enabling exceptional stability of high-nickel layered cathodes Nickel-rich layered cathodes suffer from unstable interface and structural collapse, leading to poor cycling stability in conventional carbonate-based electrolytes. Ionic liquid electrolytes promise to enable high-safety and high-specific energy lithium metal batteries employing nickel-rich cathodes.
