英文摘要 | LiNixMnyCo1-x-yO2 (NMC) cathode materials with Ni >= 0.8 have attracted great interest for high energy-density 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 degrees 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 degrees 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. |
