Chicago Tribune: Startup announces big breakthrough for electric vehicle batteries
On March 28, 2012
For years, the electric vehicle industry has been eager to build a better electric car battery: one that extends range while having a longer overall life, is affordable, quick-charging and safe.
Now Envia Systems, a start-up based in Newark, Calif., has announced it has achieved a critical milestone: a rechargeable lithium-ion battery with an “energy density” of 400 watt-hours per kilogram, the highest energy density known to be recorded.
When commercialized, Envia says the 400 wh/kg battery, with a range of 300 miles and a cost of about $25,000, will slash the price of electric vehicles and make them more affordable for mainstream consumers.
