UDRI’s new battery great for electric cars: "The University of Dayton Research Institute’s new solid-state technology for a rechargeable lithium battery, which would draw oxygen from the air around it, could offer the long service life that is needed for electric transport power in a car, according to the leader of UDRI’s battery technology team.
Manufacturers and owners of hybrid and all-electric cars would want power batteries that would last as long as the vehicle, perhaps a decade, said Binod Kumar, a research engineer and leader of UDRI’s electrochemical power group. The UDRI technology could meet that need, he said Thursday, Nov. 19.
Today’s hybrid cars have gasoline engines to supplement the electric motor. All-electric cars would require advanced batteries, with the capability to last longer between recharges.
Kumar and his team said they have developed and tested a completely solid-state, rechargeable lithium-air battery, which they said is much more stable than conventional lithium-ion batteries that contains liquid and can rupture, catch fire or explode if exposed to short-circuit or excessive heat. UDRI holds patents on parts of the technology and will apply for additional patents, Kumar said.
Dan Rastler, manager of the energy storage program for Electric Power Research Institute, a nonprofit independent research group funded by the electric utility industry, said his organization is interested in knowing more about UDRI’s work. Scientists at IBM Corp.’s Almaden Research Center in California, and researchers in Japan, also are trying to develop improved lithium rechargeable batteries because of the growing demand and potential markets as power sources in cars; laptop computers, electric utility grids and as backups to solar or wind power generating systems."
