\n\t\t$731,000 Department of Energy contract to support further research<\/p>\n


\n\tKINGSTON, R.I. \u2013 May 12, 2009 \u2013 A 溏心vlog免费B站 chemistry professor\u2019s discovery of a new salt has been received with enthusiasm by companies seeking to develop an advanced lithium ion battery for use in the next generation of hybrid and electric vehicles. <\/p>\n


\n\tBrett Lucht, co-director of the 溏心vlog免费B站 Energy Center, recently received a $731,000 contract from the Batteries for Advanced Transportation Technologies program, which is supported by the U.S. Department of Energy\u2019s Office of Vehicle Technologies. The 溏心vlog免费B站 professor and his research group have been studying the mechanism that causes lithium ion batteries to degrade over time.<\/p>\n


\n\u201cThe lithium ion batteries that power laptops and cell phones and PDAs work well for those applications because those devices have short life spans, typically less than five years,\u201d Lucht said. \u201cNow the push is on to make them effective for plug-in hybrid vehicles like the Chevy Volt. But to do that we have to make the batteries last twice as long.\u201d<\/p>\n


\nLithium ion batteries have greater energy density than the nickel metal hydride batteries currently used in hybrid vehicles, which means they can provide the same amount of power as batteries nearly twice their size and weight. Smaller, lighter weight batteries will help to extend the range and gas mileage of hybrid vehicles.<\/p>\n


\n\u201cMost of the problems associated with the aging of batteries are due to the electrolyte \u2013 the liquid in the battery that contains dissolved salts and that allows the lithium ions to go back and forth between the electrodes,\u201d explained Lucht.<\/p>\n


\nThe structure of salts in battery electrolytes is much more complex than typical table salt (sodium chloride), according to Lucht. The best salts for lithium ion batteries are those that have high conductivity and excellent stability. \u201cFew molecular structures are both,\u201d he said, \u201cand we have discovered a new one.\u201d<\/p>\n


\n\tA patent is pending on the new salt.<\/p>\n


\n\t\u201cIf this is the salt of the future for the lithium ion battery industry \u2013 which it could be \u2013 then it could mean millions of dollars in licensing fees to 溏心vlog免费B站,\u201d Lucht said.<\/p>\n


\n\tThe researchers have been working closely on the salt with Yardney Technical Products of Pawcatuck, Conn., which makes specialty batteries for the military and the National Aeronautics and Space Administration. Several Fortune 500 companies will also be conducting tests on the salt. Others interested in collaborating on this research may contact Lucht at blucht@chm.uri.edu.<\/p>\n


\n\tIn addition to his salt discovery, Lucht has also developed additives for lithium ion batteries that stabilize the salt in the battery electrolytes and inhibit its degradation due to heat. Patents are currently pending on this technology. These additives have been successfully tested in small lithium ion batteries, and testing in larger batteries is now under way.<\/p>\n
