Fluorinated High-Voltage Electrolytes To Stabilize Nickel-Rich Lithium Batteries.

As state-of-the-art (SOA) lithium-ion (Li-ion) batteries approach their specific energy limit (∼250 Wh kg), layer-structured, nickel-rich (Ni-rich) lithium transition metal oxide-based cathode materials, e.g., LiNiMnCoO (NMC811), have attracted great interest owing to their practical high specific capacities (>200 mAhg).
