This Monday, California-based Envia Systems made an announcement that could mean big things for the mainstream acceptance of electric vehicles. The company claims to have broken the world record for energy density in a rechargeable lithium-ion cell, with an automotive-grade battery that reportedly has a density of 400 watt-hours/kilogram (Wh/kg). Not only is that figure two to three times higher than what is currently possible with commercially-available cells, but Envia also claims that its battery should cost less than half the price of existing li-ion batteries.
