This wave of new materials burst from the lab in 2017, when Tesla faced a pivotal moment in its history. The company had released two successful luxury car models, but in its effort to become a major automaker, it gambled the company’s future on making a cheaper, mass-market vehicle.When Tesla released its Model 3, it had a secret technical edge over the competition: a material called silicon carbide. One of the key parts of an electric car is the traction inverters, which take electricity from the batteries, convert it into a different form and feed it to the motors that turn the wheels. To get the pin-you-to-your-seat acceleration that Teslas are known for, traction inverters must pump out hundreds of kilowatts, enough power to supply a small neighborhood, while being dependable enough to handle life-or-death highway use.
Maybe you knew about SiC, but I did not!
