Nitrile-assistant eutectic electrolytes for cryogenic operation of lithium ion batteries at fast charges and discharges [PDF]

, 2014
The charge/discharge characteristics of lithium ion batteries at low temperature (LT = -20 ??C) are enhanced by using ethylene carbonate (EC)-based electrolytes with the help of assistant solvents of nitriles. Conventional liquid electrolytes (e.g.
