Electrolytes: Advanced Electrolytes for Fast‐Charging High‐Voltage Lithium‐Ion Batteries in Wide‐Temperature Range (Adv. Energy Mater. 22/2020)

This is the authors' abstract. We don't add key points for this paper.

In article number 2000368, Wu Xu and co-workers report the fabrication of an advanced localized high-concentration electrolyte with a high oxidation potential over 4.9 V. This electrolyte enables formation of ultrathin, uniform, robust and conductive electrode/electrolyte interphases on both graphite anodes and Ni-rich cathodes. Gr||NMC811 cells using this electrolyte in a range of 2.5–4.4 V achieve excellent long-term cycling stability at 25 and 60 °C, fast-charging/discharging rate capabilities, and superior low-temperature discharge performance down to −30 °C.
