Scientists have created a battery whose technology in principle could power electric cars and other energy-hungry devices far better than current lithium-ion batteries, but it remains years away from commercial use.
Researchers at the University of Cambridge on Thursday announced the creation of a laboratory demonstration model of a lithium-oxygen battery that overcomes many of the barriers that have held back the development of this technology, according to an agency.
They said the battery boasts very high energy density, is about 93 percent efficient - better than previous efforts - and can be recharged more than 2,000 times.
