LiNixMnyCo1-x-yO2 (NMC) cathode materials with Ni = 0.8 have attracted great interest for high energy-d. lithium-ion batteries (LIBs) but their practical applications under high charge voltages (e.g., 4.4 V and above) still face significant challenges due to severe capacity fading by the unstable cathode/electrolyte interface. Here, an advanced electrolyte is developed that has a high oxidation potential over 4.9 V and enables NMC811-based LIBs to achieve excellent cycling stability in 2.5-4.4 V at room temperature and 60°C, good rate capabilities under fast charging and discharging up to 3C rate (1C = 2.8 mA cm-2), and superior low-temperature discharge performance down to -30°C with a capacity retention of 85.6% at C/5 rate. It is also demonstrated that the electrode/electrolyte interfaces, not the electrolyte conductivity and viscosity, govern the LIB performance. This work sheds light on a very promising strategy to develop new electrolytes for fast-charging high-energy LIBs in a wide-temperature range. In the part of experimental materials, we found many familiar compounds, such as Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6)
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.Product Details of 872-36-6
