The new battery in the Model S allowed the car to cover 752 miles on a single charge, according to Our Next Energy.
According to Car and Driver, the startup installed a much higher capacity battery in the sedan, which increased its range by almost 90 percent.
The new battery had a capacity of nearly double the kilowatt-hours, adding an impressive 99.8 kWh of energy compared to the original battery.
The new battery pack, dubbed the "Gemini 001", was able to fit into the same space as the original battery, but using safer and more sustainable methods.
There are road conditions.
In a December test, the Model S drove for almost 14 hours at an average speed of 55 mph. The car was on a dynanometer, which is essentially a treadmill for cars, and it was able to keep up a steady 55 mph pace.
Car and Driver says that the company is still relying on the use of compounds that come with a huge environmental cost, despite promises of a more sustainable approach to EV batteries.
The battery used in the Model S test was high-energy. The mining of cob is linked to unethical and costly practices.
It is an impressive feat that we can pack a lot more energy into a single electric car's battery, and that bode well for the future adoption of electric alternatives, as range anxiety is still a big limiting factor.
EV makers are looking to reduce both their environmental and ethical burden on the world by looking to go cobalt-free in the long-term.
We hope that more widespread EV adoption will get us there.
A Michigan startup has a prototype battery for the Model S.
There is more on EV range.
