An Israel-based battery company has demonstrated an aluminum-air chemistry that it claims can deliver as much as 1,000 miles per charge to electric cars. Clean technology company Phinergy, teaming with Alcoa, demonstrated the new electric car battery on a racetrack in Montreal this week in association with the Canadian International Aluminum Conference. At the demonstration, the two companies suggested the new technology would be used as an electric car range extender, in conjunction with a small conventional lithium-ion battery.
