Nanostructured Manganese Dioxides for Li-Ion Batteries

51023-98-I Nanostructured Manganese Dioxides for Lithium-Ion Batteries--US Nanocorp, Inc., 20 Washington Avenue, Suite 106, North Haven, CT 06473-2343; (203) 234-8024 Dr. David E. Reisner, Principal Investigator Dr. David E. Reisner, Business Official DOE Grant No. DE-FG02-98ER82706 Amount: $75,000 Limited power source performance and excessive cost have precluded the general public¿s acceptance of hybrid and electric vehicles. Fundamental improvements in active materials that are used in energy storage and conversion systems are needed. Cost reductions in terms of dollars per kilowatt-hour must be achieved through improved performance and price reduction of system components, especially the battery materials. Nanophase battery materials may increase energy density and rate capability compared to standard lithium batteries. This project will develop nanophase active battery materials through the use of an aqueous solution reaction (ASR) synthesis technique. In Phase I, nanophase manganese dioxide cathode materials will be prepared and their physical properties will be evaluated; nanophase manganese dioxide will be processed into electrodes; lithium-ion lab cells will be fabricated with electrodes from the manganese-dioxide materials; and the electrodes will be electrochemically evaluated. Commercial Applications and Other Benefits as described by the awardee: Higher energy density rechargeable batteries are needed for a myriad of applications, especially for portable power in both the military and commercial sectors. Consumer applications include cellular phones, notebook computers, cordless power tools and mowers, and hybrid and electric vehicles._
