It is reported that Tesla's battery materials department has laid off half of its employees, and the highly-anticipated 4680 battery department has laid off more than 20% of its employees, leaving only about 800 people. It is reported that Tesla's top management has proposed the goal of making its own batteries cheaper than suppliers at the beginning of this year. If this goal cannot be achieved by the end of the year, Tesla may abandon the 4680 project.
