The high-end 2013 Tesla Model S with an 85-kilowatt-hour lithium-ion battery pack is EPA-rated at 265 miles of range. But as a commenter on the Tesla Motors forum and a recent article on the stock investing site SeekingAlpha have noted, Tesla has filed for eight separate patents on uses of metal-air battery technology.
