Elon Musk reveals new battery design at Tesla Battery Day. The new “biscuit tin” battery cell is cylindrical in design, and it’s still using lithium-ion chemistry.
Musk explained about the new batteries:
“Important note about Tesla Battery Day unveil tomorrow. This affects long-term production, especially Semi, Cybertruck & Roadster, but what we announce will not reach serious high-volume production until 2022. It’s 1000% to 10,000% harder than making a few prototypes. The machine that makes the machine is vastly harder than the machine itself.”
Many exciting things will be unveiled on Battery Day 9/22 ⚡️
