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 Army discovered that using the 1M LiPF6 1EC:1EMC:1DMC electrolyte can meet ITAS low temperature requirements at -40/spl deg/C and still provide 71% of the room temperature capacity. This is about 40% better than silver zinc at low temperature.
