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

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

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

The geared-up US Army ssoldier of the 21st century packs about 25 pounds of batteries on a typical mission, so it’s no surprise that the Army continually obsesses over improving its energy storage resources. In the latest twist, the Army is giving lithium-ion batteries another chance, only this time with a new liquefied gas electrolyte.Next-Generation Energy Storage: Why The Army Wants To Make Liquefied Gas Electrolytes HappenConventional lithium-ion batteries deploy a liquid electrolyte, in which a lithium salt is dissolved by a solvent. Normally it’s a worry-free environment, despite the presence of the solvent. However, a defective or punctured battery can become a fire hazard.Lithium-ion batteries are ubiquitous throughout modern life, and that thing about puncturing is not a concern for most people in most situations. However, it is a particular hazard for soldiers and their equipment, along with crushing and other potential impacts that may be incurred during field missions, which explains why the Army is keen on identifying the next generation of better, safer lithium-ion batteries.The US Department of Defense took a big step into the future of lithium-ion energy storage a few years ago, when it lent an assist to help the Illinois startup NanoGraf develop a new silicon anode formula, aimed at reducing the weight and improving the performance of lithium-ion batteries.Then came a $10 million award from the Army to help NanoGraf get a factory for its silicon formula off the ground in Chicago. Now the Army is following up with another $550,000 in funding, to hook up NanoGraf’s 3.8 Ah 18650 silicon anode battery cell with a liquified gas electrolyte developed by the California firm South 8 Technologies.The six-month project will put the new battery through its paces in a series of temperature and nail penetration tests.“Successful completion of the testing will validate the extreme cold temperature performance of the cell and maintain existing capacity and cycle life, allowing the cell to operate down to -60 degrees, and up to +60 celsius and pass the safety test,” NanoGraf explains.What’s So Great About Liquified Gas Electrolytes?The Army energy storage project follows an award of $3.152 million to South 8 from ARPA-E, the cutting edge funding office of the Energy Department, as part of a broader program to push the envelope on battery performance for electric vehicles
