Will Tesla Battery Day Introduce Next-Gen Battery Similar to 4070 Cells for Cybertruck & Semi?

Will Tesla Battery Day Introduce Next-Gen Battery Similar to 4070 Cells for Cybertruck & Semi?
During the Q4 2019 Earnings Call, Tesla CEO Elon Musk shared some details about the company's progress in the development of Tesla batteries. He emphasized that Tesla's acquisition of Maxwell Technologies is an “important piece of the puzzle” to meet demand for the “bad-ass futuristic” Cybertruck and for its broader product ramp-up.

Battery manufacturing is fundamental to the production of more electric vehicles. “The thing we’re going to be focused on is increasing the battery production capacity because that’s very fundamental. Cause if you don’t improve battery production capacity, then you end up just shifting unit volume from one part to another, and you haven’t actually produced more electric vehicles," Musk said.

In February, Tesmanian exclusively reported several details regarding Tesla's new battery cells and batteries, which, judging by recent information from other sources, are true.

In February, our anonymous source said that the new Tesla battery will have at least 30% more capacity and will be several times cheaper to manufacture. The production process will be extremely efficient and will significantly save on capital costs for equipment. In this scenario, a 130kWh pack seems possible.

It also became known that the new cell will have a diameter of approximately 1.57 inches. The new battery will have a different form factor, so most likely it will be used for Semi and/or Cybertruck.

The Cybertruck and Semi, in particular, would greatly benefit from new battery technologies. This is a completely new level of transport. These Tesla products are designed to move heavy goods at long distances. It makes sense, then, that Tesla would ensure they’ve got the most cutting-edge battery tech to support these one-of-a-kind vehicles.

The main focus for Tesla is on increasing the capacity of the battery cells. With the old battery cells, the company would have to increase the number of batteries per vehicle, which would require more space. That is why it is more likely that Tesla was able to achieve a capacity increase within the battery cell itself.

This means that now, the battery can take up as much space in the vehicle as before, but have significantly more capacity. This advancement not only reduces cost—as there are fewer casings and cells per package—but importantly also enhances production speed.



"Battery Day people. Wait until Battery Day. It's gonna blow your mind. It blows my mind, and I know it!", said Musk.
