Abstract
Prototype D size lithium ion cells containing the Army 1 M LiPF/sub 6/ 1EC:1DMC:1EMC electrolyte have been demonstrated to operate at -30/spl deg/C. With greater than 73% of the initial capacity at 20/spl deg/C. The cell with Army electrolyte operates at higher voltage and higher energy density across the temperature ranges and at various rates. When the lithium ion cell cycling between 40/spl deg/C and -20/spl deg/C can cause the capacity fade rapidly as well.
