Primary Batteries
In recent decades, lithium has literally transformed the potential of primary batteries. These battery systems have come to dominate the high-performance primary battery market—in everything from medical implants to high performance military applications such as space sensors and missile power—due to the light weight, high voltage and energy output, and outstanding shelf life of lithium chemistries. While all lithium cells share these and other generalized benefits, Quallion's customers can select from several lithium chemistries that have specialized characteristics and applications.
Lithium/Carbon Monoflouride (CFx) batteries were among the first commercially successful lithium battery systems. They have remained so attractive because the chemistry delivers very high energy density, long storage life, very good safety record, wide temperature, and very low self-discharge. These batteries are found in a wide range of low-to-medium current applications for military, aerospace, electronics, and medical customers. The following summarizes the general characteristics for CFx chemistry:
Nominal Voltage: 3.2 V; operating voltage 2.5-2.7 V
Specific Energy: 590 Wh/k
Energy Density: 1050 Wh/L
Temperature Range: -40°C to 85°C
Self Discharge: 0.5% per year (at 20°C)
Quallion offers specialized technology improvements to its CFx cells and batteries geared for the medical, aerospace and military markets. These improvements draw upon Quallion's extensive knowledge of Li-ion cell manufacturing technologies. These improvements have allowed the company to build large size CFx cells (15 Ahr D-size) capable of relatively high rates of discharge (C/5) and an operational capability over a wide temperature range (-30°C to 60°C).
