The days of reduced EV range may be over. The startup NextEnergy would have managed to run a Tesla Model S for 1,200 kilometers on a single charge thanks to a brand new prototype battery called Gemini. Thus equipped, the Tesla Model S breaks Mercedes’ previous range records with its EQS (770 km) and its EQXX (1,000 km).
The Tesla Model S has traveled almost 1200 km at the average speed of 80 km/h, knowing that the installation of the Gemini battery did not affect the general properties and performance of the vehicle. The Gemini battery offers an energy capacity of 416 Wh/L compared to 245 Wh/L and has a graphite anode + nickel-cobalt-manganese cathode combo. The density of the new battery still adds 331 kg to the Tesla.
It remains to be seen when this new generation of battery will be able to be mass produced, if that is possible with current manufacturing techniques.
