Roles of Nonflammable Organic Liquid Electrolyte in Stabilizing the Interface of the LiNi_0.8Co_0.1Mn_0.1O₂ Cathode at 4.5 V and Improving the Battery Performance

Driven by a high demand for safe lithium-ion batteries (LIBs) with no risk of fire, we develop a nonflammable organic liquid electrolyte, which is composed of 1 M lithium hexafluorophosphate salt and propylene carbonate and fluorinated linear carbonates. Herein, we report the studies of the effects of the nonflammable electrolyte on the surface chemistry and structure of the nickel-rich LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode under the expanded...
