The new Gemini 001 battery pack prototype by Our Next Energy (ONE) propelled the Tesla Model S for 14 hours straight around Michigan in the cold mid-December temps. ONE managed to double the battery density of Tesla's stock 103.9 kilowatt-hours battery by using innovative packaging technology and proprietary chemistry. ONE's high-density battery pack beat the world record for a Model S range by covering 752 miles on winter highways, and 882 miles on a dynamometer in the lab.
