Contour Energy Systems, a manufacturer of advanced battery systems, has highlighted the application of its new Lithium/Carbon Fluoride (Li/CFx) primary batteries in medical devices by publishing an informative Medical Application Brief.
The proprietary Fluoronetic fabrication technique integrates multi-layered carbon nano-materials with innovative manufacturing processes to achieve operation over a wide temperature range and long shelf life. Furthermore, the patented “Tunable Cathode” enables the basic properties of the cell to be fine-tuned for power density and optimal energy. The LiCFx cells are suitable for medical applications because of their considerably flat discharge profile, light weight and low internal resistance.
Key medical applications of the Li/CFx batteries are:
- Drug infusion pumps
- Bone-growth stimulators
- Glucose monitors
- Defibrillators and
- Other implantable and external devices
When compared to other lithium battery chemistries, Li/CFx offers high volumetric energy density, high gravimetric energy density, exceptional shelf life, wide temperature range, and optimum performance/price. A useful table is provided in the application brief that compares performance features of Contour's Li/CFx technology with the other primary lithium battery chemistries.
Li/CFx primary batteries from Contour Energy System are offered in coin and pouch cell configurations. The Li/CFx coin cell batteries have exclusive 'Japanese-level' quality and offers comparable unit pricing, according to Joe Carcone, Sales and Marketing VP. Furthermore, he added that the company’s custom pouch cells are fabricated in the U.S."
