What’s New with Tesla Battery Day?

On Sunday, Musk announced that Tesla is aiming to hold the Battery Day and shareholder’s meeting on September 15, but it doesn’t look like it’s set in stone:

Tentative date for Tesla Shareholder Meeting & Battery Day is Sept 15.

The CEO added that the event “will include tour of cell production system.”

He is likely referring to the battery cell production line that Tesla is setting up in Fremont as part of the previously mentioned *Roadrunner project.

*Dit zal ook ter sprake komen:

Electrek has learned more about Tesla’s secret project “Roadrunner”: applying “the machine that builds the machine” strategy to produce cheaper battery cells on a massive scale.

$100 per kWh has been described as the price target for batteries to enable electric vehicles to reach a price parity with gasoline cars without subsidies.

If combined with mass production, it’s considered the “holy grail” of EV adoption since it would enable high-volume production of relatively affordable and/or high-margin electric cars.

Tesla’s partnership with Panasonic has led to an industry-leading battery cost, but the automaker is looking to take things a step further by making its own cells.

For a few months now, Tesla has been rumored to be working on making its own battery cells for its electric vehicles.

It started with the acquisition of Maxwell, a supercapacitor manufacturer with some battery cell technology, and later, at its annual shareholder’s meeting, Tesla all but confirmed that it’s going to manufacture its own battery cells.

Later, we reported that Tesla referred to battery cells as a new “product line” for the company in some job listings for cell manufacturing.

Earlier this month, we shared an exclusive report about Tesla building a battery cell pilot production line in Fremont.

Now sources have told Electrek that the secret project is called “Roadrunner,” and it will aim to achieve mass production of a new battery cell that will be more energy-dense and cheaper.

The cells are using technologies developed by Tesla’s internal teams, including work from its research lab in Canada led by Jeff Dahn, and new technologies recently acquired through the acquisition of Maxwell.

Maxwell’s dry electrode technology would enable Tesla to produce cheaper cells with higher-energy density that would enable them to use less batteries per vehicle and still achieve longer range:

M a.w. Tesla blijft zijn voorsprong behouden of loopt verder uit op batterijgebied. Zie figuur en cijfers disruption zone.

Van 300 Wh/kg naar 435 Wh/kg niveau batterijcel, hopelijk al 2021-2022. Ook 385 Wh/kg is een significante verbetering (+30%)
Het batterijpack zelf zou wel eens 100-150 kg lichter kunnen worden.
