Cobalt, another key material for batteries, is also sharply higher though it has retreated from a high earlier this year. The same is true for metals used elsewhere in the car, such as steel, aluminum and copper, which have also seen in prices traded in public markets rising. There were further increases in late April and another in early May. Prices for lithium, a key material used in EV batteries, have more than doubled in trading markets. Tesla plans to increase production by more than 50% this year, and thus is increasing its demand for batteries by the same amount.
It's common for the prices of metal to go up, but still working on automotive systems suggests that something will be gained from this.
