Porsche Invests In Battery Startup South 8 To Boost Cold-Weather Ev Performance

All cars suffer when the mercury drops, but electric vehicles suffer more than most as heaters draw more power and batteries charge more slowly as the liquid electrolyte inside thickens. Drivers in Chicago found this out the hard way last January after many Teslas failed to charge during a deep freeze.One startup, South 8 Technologies, says it can make cold-weather charging more reliable by filling batteries with a pressurized, liquified gas electrolyte instead of a liquid one. In the process, it hopes to slash the cost of lithium-ion batteries by 30%. For automakers, if that savings pans out, it might be too good to pass up. “The battery costs about a third of the entire car,” CEO Tom Stepien told TechCrunch. South 8 claims that its manufacturing technique can reduce the size of some of the costliest parts of a battery factory. And by injecting gas under pressure into the cell, South 8 can prevent the electrolyte from freezing until –100 degrees C, well below the point at which nearly every other solvent has turned into a solid.“At –40 degrees C, we retain 75% of the energy capacity,” Stepien said. “Everything else is a brick.”The company recently attracted new funding from Porsche Ventures in the form of a SAFE note, which will be applied to a Series B round that the company is starting to raise

South 8 Partners With Nanograf On $6.4M U.S. Army Contract To Advance Domestic Lithium-Ion Battery Production

SAN DIEGO--(BUSINESS WIRE)--South 8 Technologies (South 8), the developer of LiGas®, a liquefied gas electrolyte for advanced lithium-ion batteries, announced today that it is collaborating with NanoGraf to deliver higher energy, safer, and lighter batteries for soldiers in the battlefield. South 8’s $6.4 million subcontract with NanoGraf will support the U.S. Army Combat Capabilities Development Command C5ISR Center (DEVCOM). South 8 will develop and deliver a high-rate injection system for its LiGas electrolyte to bolster domestic production of cylindrical lithium-ion batteries under the Defense Innovation Unit (DIU)’s Family of Advanced Standard Batteries (FAStBat) initiative. U.S. soldiers are often weighed down by more than 20 pounds of lithium-ion batteries when in the field, carrying multiple battery packs as backups in case of poor performance due to extreme weather or physical damage
