Solid state rechargeable batteries offer potentially greater energy density than conventional nickel cadmium batteries and could foster the development of more sophisticated implantable medical devices and electronic equipment if successfully developed. These solid state batteries will have improved lifetimes and higher energy to the extent that they can be used to power conventional implantable devices such as the implantable gait assist device or the left ventricular assist device. More importantly, however, this research will point the way to the development of more advanced secondary batteries for powering the next generation of implantable devices. The proposed research effort will involve computer-assisted evaluation of new polymers and polymer composites which will hasten the selection of candidate materials for synthesis. These select materials will then be synthesized and characterized electrochemically to determine which are most likely to yield the desired electrochemical properties. Success in the Phase I effort will lead to commercialization of the proposed innovation through cooperation with our Phase III battery manufacturing partner. The technological success of developing a solid polymer electrolyte that is equal to liquid electrolytes will mean a whole new era for lithium batteries in the consumer market. This will occur because a competitive solid polymer electrolyte will put and end to safety problems with lithium batteries. The private sector would benefit from this technological development since the market for portable power to run the latest electronic gadget seems insatiable. With each passing year, there appears to be an ever increasing bevy of new portable electronic devices. All of these gadgets require power and batteries are the only answer. Development of improved, safe high power batteries must continue since the demand for new electronics continues unabated. The pressure for this development is market driven and will eventually be met, the proposed innovation is one possible way of meeting this demand.
