This sounds credible - a lot more than EEStor anyway (I know that is a low, low bar). May be we can get this in vehicles in 3 to 5 years.
Atul Kapadia, chairman and chief executive of Envia, said in a telephone interview. “The cost of cells will be less than half — perhaps 45 percent — of cells today, and the energy density will be almost three times greater than conventional automotive cells.”
Mr. Kapadia continued: “What we have are not demonstrations, not experiments, but actual products. We could be in automotive production in a year and a half.”
Envia’s announcement said that its packs would deliver cell energy of 400 watt-hours per kilogram at a cost of $150 per kilowatt-hour. Though it doesn’t disclose a cost breakdown, Tesla Motors rates the energy density of its Roadster’s pack at 121 watt-hours per kilogram. Envia said its energy-density performance was verified in testing of prototype cells at the Naval Service Warfare Center’s Crane evaluation division.
