Fred Lambert\u00a0 <\/span><\/u>– Feb. 26th 2020<\/p>\n

\"\"<\/span><\/p>\n

<\/p>\n

Electrek<\/em> has learned more about Tesla\u2019s secret project \u201cRoadrunner\u201d: applying \u201cthe machine that builds the machine\u201d strategy to produce cheaper battery cells on a massive scale.<\/span><\/ins><\/ins><\/ins><\/p>\n

$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.<\/p>\n

If combined with mass production, it\u2019s considered the \u201choly grail\u201d of EV adoption since it would enable high-volume production of relatively affordable and\/or high-margin electric cars.<\/p>\n

Tesla\u2019s 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.<\/p>\n

For a few months now, Tesla has been rumored to be working on making its own battery cells for its electric vehicles.<\/p>\n

It started with the acquisition of Maxwell, a supercapacitor manufacturer with some battery cell technology, and later, at its annual shareholder\u2019s meeting, Tesla all but confirmed that it\u2019s going to manufacture its own battery cells<\/a>.<\/p>\n

Later, we reported that\u00a0Tesla referred to battery cells<\/a>\u00a0as a new \u201cproduct line\u201d for the company in some job listings for cell manufacturing.<\/p>\n

Earlier this month, we shared an exclusive report about Tesla building a battery cell pilot production line in Fremont<\/a>.<\/p>\n

Now sources have told Electrek<\/em> that the secret project is called \u201cRoadrunner,\u201d and it will aim to achieve mass production of a new battery cell that will be more energy-dense and cheaper.<\/p>\n

The cells are using technologies developed by Tesla\u2019s internal teams, including work from its research lab in Canada led by Jeff Dahn, and new technologies recently acquired through the acquisition of Maxwell.<\/p>\n

Maxwell\u2019s 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:<\/p>\n

\"\"

Tesla has already tested prototype cells under the Roadrunner secret project. It believes it can produce the cells in volume and use them in its vehicles and eventually in its stationary energy storage products.<\/p>\n

The automaker has been developing manufacturing equipment in secrecy, like the pilot production line in Fremont, over the last few months.<\/p>\n

Some Tesla engineers have briefly mentioned the new battery cell in comments on LinkedIn found by Electrek<\/em>.<\/p>\n

Tesla staff R&D engineer Matthieu Moors asked engineers to join the team to \u201creinvent\u201d cell manufacturing:<\/p>\n

Come join us and reinvent Li-Ion battery cell manufacturing technology!<\/span><\/p><\/blockquote>\n

Bonne Eggleston, senior manager of cell manufacturing, commented:<\/p>\n

Developing world-class battery cell manufacturing technologies to enable the next generation of low-cost, high-performance electric vehicles and energy storage products.<\/p><\/blockquote>\n

With the introduction of the new battery cells, Tesla is also working on new module and battery pack improvements, according to sources talking to Electrek<\/em>.<\/p>\n

It includes moving away from wire bonding on the cells and going with a laser-welded technology instead.<\/p>\n

Tesla president of autopilot Jerome Guillen said on LinkedIn that the battery module team is \u201ccentral to the secret sauce at Tesla\u201d:<\/p>\n

We continue to hire! In particular, for battery module mechanical design engineer. It is hard to think of a position more central to the secret sauce at Tesla. The battery module team is particularly awesome and smart.<\/p><\/blockquote>\n

One source told Electrek<\/em> that CEO Elon Musk is pushing to have one of those new battery packs with the new Tesla-made battery cells ready to install in a Model S or Model X for the \u201cBattery Investor Day\u201d in April.<\/p>\n

More information is going to be released at the event where Tesla is expected to announce the production of the cells in the US, Europe, and China.<\/p>\n

Electrek\u2019s Take<\/h2>\n

This is a massive deal. You could argue that Tesla has more experience with Li-ion battery cells than any other company on the planet.<\/p>\n

They are the world\u2019s biggest consumer of battery cells, and they have used them on hundreds of millions of cycles throughout their entire fleet.<\/p>\n

Now they are using all this data combined with its own in-house engineering talent, the R&D from Jeff Dahn\u2019s lab, and new acquisitions like Maxwell, to deliver what could very well be the most advanced Li-ion battery ever.<\/p>\n

More importantly, they are bringing to market a cell that can be mass-produced at a low cost.<\/p>\n

My understanding is that this is the battery cell that is enabling the great economics and range of the Cybertruck and Tesla Semi as well as supporting Tesla\u2019s long-term ambitions for high volume production across its lineup in the long term.<\/p>\n

I expect Tesla to announce the production of the new cell at several locations in the US, Europe, and China by the end of the year.<\/p>\n
