Toward Long-Life, Ultrahigh-Nickel Layered Oxide Cathodes for Lithium-Ion Batteries: Optimizing the Interphase Chemistry with a Dual-Functional Polymer

Boosting the Ni content in LiMO2 (M = Ni, Co, Mn, etc.) layered oxides is a promising way to establish high-energy-density, low-cost cathodes, but the poor cathode surface stability is a daunting c...
