Project BriefOpen Competition - Electronics/Computer Hardware/Communications (October 2000)High Reliability, Safe, Rechargeable Lithium Ion Battery and Battery Management SystemDevelop an advanced, long-lasting microminiature battery for implantable medical devices, capable of being recharged from outside of the body with no physical connections, enabling revolutionary treatments for diseases ranging from Parkinson's disease to limbs paralysis.

Although the medical electronics field has grown dramatically over the past two decades, battery technology has been a major factor limiting applications for devices capable of being implanted in the body. Conventional implantable batteries cannot be recharged, are relatively large, and must be replaced as often as every 18 months for high-energy applications. A joint research venture led by Quallion plans to develop a new class of highly reliable miniature lithium secondary battery technology designed to last more than 10 years with integrated battery safety management circuitry. An advanced electronics system also will be developed enabling the batteries to be recharged from outside the body using magnetic induction without any physical connections. The miniature pin-shaped battery will reduce surgical trauma and thus reduce potential post-surgical complications and enable faster recovery. The power source would make possible new implantable devices that use electrical stimulation to treat over 6.6 million Americans suffering from stroke, epilepsy, Parkinson's disease, sleep apnea, limbs paralysis, and urge urinary incontinence, representing a potential market of $1.98 billion. Such a power source could drive the implant industry into areas that have not yet been thought of and develop treatments to improve the lives of millions of people. Research participants in this venture include Teledyne Electronics Technologies (Los Angeles, Calif.), the Alfred E. Mann Foundation (Valencia, Calif.), Argonne National Laboratories (ANL), the University of Wisconsin's Organosilicon Research Center (UWORC) and Quallion, who will be leading and orchestrating all research and application efforts. Teledyne and AEMF will be working together to co-develop the miniature battery management circuitry technologies. ANL and UWORC will be developing advanced materials chemistry with ANL focusing on materials chemistry and UWORC on polymer electrolyte technologies. Quallion will be spearheading battery technologies and design efforts and work with all named participants to address full system integration. ATP support will accelerate the project by more than four years, thus jumpstarting advanced medical treatments availability to the public.
