Tesla’s New Li-ion Battery Labcoat Hero

9 years ago Guest Contributor 48 Comments

Originally published on TeslaMondo. How many times have we heard that Tesla could die at the hands of a battery breakthrough? Some labcoat hero, we’re oft-warned, could suddenly render Tesla and its Li-ion Gigafactory obsolete overnight. Well, now Tesla has contracted a labcoat hero of its own, to work with CTO JB Straubel, hardly … [continued]
