The US Army and Saft have developed a large lithium ion battery to replace
the BE-622 silver zinc battery for application for the ITAS System. The Arm
y discovered using the 1M LiPF6 1EC:1EMC:1DMC electrolyte can meet ITAS low
temperature requirements at -40 degreesC and still provide 71% of the room
temperature capacity. This is about 40% better than silver zinc at low tem
perature.
