Plenary Speaker
Strategies for Long Life Batteries: Inspiration from Batteries that Power Implantable Medical Devices
Talk
Batteries developed for implantable biomedical devices have helped enable the successful deployment of devices for the treatment of human disease. The medical devices are permanently implanted where they can continually monitor a patient and provide therapy as needed. Numerous devices have been developed to treat a diversity of human ailments including neurostimulators, cardiac pacemakers and cardiac defibrillators. While the functional requirements for the batteries used to power these devices vary, there are some characteristics that are demanded by all applications including many years of service, safety during installation and use, predictable performance, and high reliability.
Society today has significant need for portable power ranging from widely deployed consumer electronics to the expanding use of electric vehicles. While a diversity of battery types is necessary to meet the various needs for portable power, the approaches to extend the service life of batteries can draw inspiration from those used for implantable medical batteries. Examples of medical batteries and approaches to further extending their service life will be discussed.
Biography
Esther S. Takeuchi is a SUNY Distinguished Professor and holds the William and Jane Knapp Chair in Energy and the Environment in the Departments of Materials Science and Chemical Engineering and Chemistry at Stony Brook University. She holds a joint appointment at Brookhaven National Laboratory as chief scientist in the Energy and Photon Sciences Directorate.
Prior to her academic appointment, she was employed at Greatbatch, Inc., where her research focused on lithium battery research for implantable applications. Her work was instrumental in the success of the lithium/silver vanadium oxide (Li/SVO) battery, the power source enabling the widespread adoption of life-saving implantable cardiac defibrillators with approximately 300,000 devices implanted per year.
