We report a promising approach to achieve the maximum capacity (>230 mA h g-1) and high capacity retention (95% during 100 cycles) of a nickel-rich cathode of LiNi0.8Co0.1Mn0.1O2 (NCM811) by charging to 4.5 V in a non-flammable electrolyte of propylene carbonate and fluorinated linear carbonates. Our electrolyte permits the stabilization of the cathode-electrolyte interface and cathode structure at high-voltage, enabling stable and safe operation of the Ni-rich cathode for high-energy d. and high-safety lithium-ion and lithium metal batteries. The experimental part of the paper was very detailed, including the reaction process of Vinylene carbonate(cas: 872-36-6Quality Control of Vinylene carbonate)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Quality Control of Vinylene carbonate
