Tesla CEO Elon Musk sniped at Silicon Valley neighbor Apple twice during a conference call to discuss Tesla earnings on Monday.
Although the companies don’t compete directly today, Apple is reportedly building an electric self-driving vehicle under a project code-named Titan, and has attracted a number of engineers and executives away from Tesla. The Titan project is reportedly run by Doug Field, who returned to Apple in 2018 after five years at Tesla.
When asked about Tesla’s supply chain, Musk said that there’s a misperception that Tesla uses a lot of cobalt, a key material in the production of lithium-ion cells used in both smartphones and electric cars.
“Apple uses I think almost 100% cobalt in their batteries and cell phones and laptops, but Tesla uses no cobalt in the iron-phosphate packs, and almost none in the nickel-based chemistries,” Musk said. “On on a weighted-average basis we might use 2% cobalt compared to say, Apple’s 100% cobalt. Anyway, so it’s just really not a factor.”
