Aga nagu artiklitest lugeda võite, hüppasid nad nüüd välja uudisega 400Wh/kg akust mis väidetavalt ei maksagi hingehinda.
To contrast Envia's numbers with batteries in electric vehicles available today, most lithium cells fall between 100-150 Wh/kg and easily cost double to triple Envia's projected price. It also claims they will be priced somewhere in the $125 per kilowatt-hour neighborhood.
Perhaps the best part of this news is the fact that Envia's numbers aren't just based on expectations from early research. In fact, the cells in question have already undergone independent testing by the Electrochemical Power Systems Department at the Naval Surface Warfare Center (NSWC) and are expected to be commercialized by 2015.
