Because electric vehicles need to be lightweight to drive farther on the same charge, EV batteries with high specific energies are essential. The consortium, led by Pacific Northwest National Laboratory, aims to build a battery pack with a specific energy of 500 watt-hours per kilogram (compared to 170 to 200 Wh/kg typical today). Reaching 500 Wh/kg while achieving 1,000 electric vehicle cycles would result in a significantly smaller, lighter- weight, less expensive battery pack and more affordable EVs.
