Tesla begins gigafactory battery cell Mass production Yay!

Post by MitchJi » Jan 04 2017 6:49pm

For ES this means that cheap (from wrecking yards) OEM quality 2170 modules and cells are a big step closer . Does anyone know what the C-rate of Tesla’s cells? Quite a lot of uninformed speculation that it's high enough to support 350-450 kw charging as tweeted by Elon, mentioned here:

Battery Cell Mass Production Begins at the Gigafactory

The Tesla Team January 4, 2017

Tesla’s mission is to accelerate the world’s transition to sustainable energy through increasingly affordable electric vehicles in addition to renewable energy generation and storage. At the heart of these products are batteries. Today at the Gigafactory, Tesla and Panasonic begin mass production of lithium-ion battery cells, which will be used in Tesla’s energy storage products and Model 3.

The high performance cylindrical “2170 cell” was jointly designed and engineered by Tesla and Panasonic to offer the best performance at the lowest production cost in an optimal form factor for both electric vehicles and energy products.

Production of 2170 cells for qualification started in December and today, production begins on cells that will be used in Tesla’s Powerwall 2 and Powerpack 2 energy products. Model 3 cell production will follow in Q2 and by 2018, the Gigafactory will produce 35 GWh/year of lithium-ion battery cells, nearly as much as the rest of the entire world’s battery production combined.

The Gigafactory is being built in phases so that Tesla, Panasonic, and other partners can begin manufacturing immediately inside the finished sections and continue to expand thereafter. Our phased approach also allows us to learn and continuously improve our construction and operational techniques as we continue to drive down the cost of energy storage. Already, the current structure has a footprint of 1.9 million square feet, which houses 4.9 million square feet of operational space across several floors. And we are still less than 30 percent done. Once complete, we expect the Gigafactory to be the biggest building in the world.

With the Gigafactory online and ramping up production, our cost of battery cells will significantly decline due to increasing automation and process design to enhance yield, lowered capital investment per Wh of production, the simple optimization of locating most manufacturing processes under one roof, and economies of scale. By bringing down the cost of batteries, we can make our products available to more and more people, allowing us to make the biggest possible impact on transitioning the world to sustainable energy.

Finally, bringing cell production to the U.S. allows us to create thousands of American jobs. In 2017 alone, Tesla and Panasonic will hire several thousand local employees and at peak production, the Gigafactory will directly employ 6,500 people and indirectly create between 20,000 to 30,000 additional jobs in the surrounding regions.
Best Wishes!

That's fantastic!

So happy for Tesla and all things that breathe!

There's a short video here:
https://cleantechnica.com/2017/01/05/te ... gafactory/


Those wanting to take a look at the newly started battery cell production at the Tesla + Panasonic Gigafactory in Nevada can now do so … to some degree. Tesla has posted a short video teasing the beginning of cell mass production there.

Description from someone who was there:

doctoxics said: ↑
Yuri_G. What are we looking at.
Those are individual 21-70 cells close to the end of their production line. The spiral layers of cathode, anode and isolater have been emplaced; the electrolyte fluid has been inserted and the top cap has been welded on.

Effectively all that remains is for it to go through a water wash in order to remove any spilled electrolyte, which otherwise can cause surface rust, then every single cell undergoes a physical QC (scratches, bad welding, etc), and an electrochemical one (voltage, etc).

Then it undergoes a curing or tempering; this enables the LiOH-filled electrolyte to nestle into the latticework of the cell-it's not an instantaneous process.
Best Wishes!

The good news, coinciding with rather pernicious political events in the USA in January, restores a sense of hope and wonder - thank you Tesla & Elon Musk! I remain most interested in the Powerwall, which as of January 1st, is now available for purchase and actual delivery, version 2.0 - https://www.tesla.com/powerwall
One 14 kWh Powerwall battery $5,500
Installation and supporting hardware starts at $1,500
Total estimate $7,000
Requires $500 deposit for each Powerwall
I've explored battery backup to solar for the better part of the last several years, and this is THIS IS IT moment for me. Now saving my dollars. Its a lifestyle thing for us sustainability folk looking for LEV + solar + battery for 100% energy from the sun. :mrgreen:

Tesla's greatest hope for going mass market could present a threat to its car factory:
http://finance.yahoo.com/news/teslas-gr ... 00485.html

(Begins:)
Tesla has started production of lithium-ion batteries in partnership with Panasonic at its massive Gigafactory in Nevada.

Meanwhile, the carmaker is gearing up to build 500,000 vehicles by 2018 at its plant in Fremont, California.

Which of these two manufacturing challenges do you think is bigger?

That's easy: the cars.

Here's a link to the video of cell production on twitter.

Musk Battery Works Fill Utilities With Fear and Promise:

“The mortal threat that ever cheaper on-site renewables pose” comes from systems that include storage, said Amory Lovins, co-founder of the Rocky Mountain Institute, a Snowmass, Colorado-based energy consultant. “That is an unregulated product you can buy at Home Depot that leaves the old business model with no place to hide.”
