One of Tesla’s earliest challenges involved the thousands of lithium-­ion batteries the company intended to pack into its e-sports car, the Roadster, which was produced from 2008 to 2012. Problem: They caught fire embarrassingly often. Enter Gene Berdichevsky, employee No. 7. He helped solve the issue using a mix of heat transfer materials, cooling channels and battery arrangements that ensured any fire would be self-contained.

Berdichevsky has now co-founded Sila Nanotechnologies, which aims to make better lithium-ion batteries using silicon-based nanoparticles. Silicon has almost 10 times the theoretical capacity of the material most often used in lithium-ion batteries, but it tends to expand during charging, causing damage. Sila’s particles, however, are porous enough to accommodate that expansion, offering the promise of longer-lasting batteries. Lucky Nr. 7 saves the day again.
