A Breakthrough in Electric Vehicle Range
We’ve talked a lot about electric vehicles and “range anxiety” (see here, here, and here), but we might finally have a cure – researchers at the University of Waterloo may have tripled the range of EVs.
According to the University release, scientists used negative electrodes made of lithium metal, which could, theoretically, triple the battery storage capacity, from about 200 to 600 km (on average).
Researchers solved two pressing challenges – microscopic structural changes to the lithium metal and potential corrosion – by “adding a chemical compound made of phosphorus and sulfur elements to the electrolyte liquid that carries electrical charge within batteries.”
“We wanted a simple, scalable way to protect the lithium metal,” said Quanquan Pang, who led the research at the University of Waterloo. “With this solution, we just add the compound and it works by itself.”
Combine this breakthrough with other recent announcements and you’ve got something special – a ride-sharing service with an absurdly high range. A sports car that doubles as a road warrior. Delivery trucks that can go all day between charges.
