Tesla Gigafactory

Tesla Gigafactory construction in Nevada well underway!

The 34th International Battery Seminar, scheduled for March 20th-23rd in Florida, will be honored this year by major EV battery manufacturers like Tesla and BYD.

Kurt Kelty, Senior Director, Cell Supply Chain & Business Development at Tesla Motors will have give a keynote presentation on the Gigafactory’s Material Sourcing and Cell Production including current cell production for Tesla Energy’s Powerwall and Powerpack energy storage products.

Via Green Car Congress:

“Kelty is the Senior Director of Battery Technology at Tesla Motors in Palo Alto, California. His team in Palo Alto is responsible for setting and implementing Tesla’s battery cell usage strategy. Kelty is responsible for the technical exchanges and commercial negotiations with each of the battery cell suppliers and early stage battery cell developers.

He leads the team that is particularly focused on evaluating the performance and reliability of cells. Kelty also leads the partnerships and battery cell material sourcing efforts at the Gigafactory. He is responsible for forming and implementing relationships to co-locate at the Gigafactory or to source materials from external suppliers. Ultimately, Kelty is responsible for all the material costs and performance of the battery cells made at the Gigafactory.”

Much as I’m a fan of Tesla Motors, and much as I’m excited about how Gigafactory 1 represents a new era in enabling auto makers to make long-range PEVs (Plug-in EVs) in large numbers, at the same time it’s a sad commentary on the lack of significant recent advancement in battery tech that the keynote speech is going to be about ways to reduce costs in making batteries using existing li-ion chemistry.

Where are the solid state batteries? Where are the batteries with graphene-enhanced electrodes? Where are the flow cells with significantly improved power output?

Looking toward even more radical improvements, where is the “all electron battery”? Where is the betavoltaic (nuclear powered) generator?

Dammit, it’s 2017. Where is my fully autonomous, flux capacitor powered flying car?!? 😉



I share your desire to see the next gen batteries.

Looks like Dyson is bringing EVs to market based on the Sakti3 solid state battery. This could be interesting, but is probably 5+ years out.

VW bought Quantumscape battery technology, but VW is dragging their feet on EVs.

Tesla could deliver some interesting news regarding the 21700 cell chemistry, but you’re probably right … it’ll be around economies of scale and reaching a major milestone in cost per kW at the pack level.

Most other automakers are using LG Chem cells.

Samsung SDI announced an increase … by the year 2020? *sigh*

“Most other automakers are using LG Chem cells.”

When you see how long the list of automakers using LG Chem batteries is, you have to wonder why LG Chem is not at the top of the list of battery makers by volume.

Are they all just making concept cars?

LG only now have competitive battery chemistry.

Panasonic had it in 2010, and that’s what enable Tesla to become market leader in Plug ins by battery pack total sold capacity.

That’s what skyrocketed Panasonic to it’s dominant position it holds now.

LG had no such successful customers to date. Hence LG is 30-40% of Panasonic capacity.

Which by the way guarantees that nobody can out sell Tesla in next 2-5 years (because LG do not have batteries for that hypothetical Tesla killer)

LG Chem has been making batteries as well built as Panasonic does for 5 or 6 years. In point of fact, it looks like LG packs may outlast Tesla/Panasonic packs due to the excellent pack/thermal management system that GM has used.

Panasonic has a better client in Tesla, though. Tesla has the vision whereas GM has the MBA’s blinkered mindset that has crippled their electric cars so far. Now that LG price per kWh is so much lower than it used to be, the difference between Panasonic and LG is a bit less noticeable, though Panasonic still builds Tesla cells for less than LG does for GM.

And who knows, maybe the next electric car from GM will be one a substantial portion of the car buying public REALLY WANTS to buy.

LG competitive ?

Please point out 100 cars with a used range of 100k km, and battery degradation seen.

Today, no-one else is *near* Tesla on car battery systems re: longevity, cost, or rate of charge as a C- value.

Tesla has approx 5% degradation over 150.000 km, and the rate of wear is slowing down.
The trend lines are clear.
After 3 years heavy-use cars, and 98% of all cars, 5% and less than 1% year/year wear.

Thus, to go down to 80%, another 14-15 years might be expected…

This does not mean LG and or others (BYD) may not catch up.
So far, we have seen zero evidence of this.

Evidence, as in cars on the road, with 100kW+ charging, in the real world.

Today, there are exactly zero other cars charging at 100 kW plus.

Yes, thank you for raising the subject.

I suppose if I had more patience, I could let the matter rest for the five years it typically takes to develop a commercial product. Unfortunately, as you say, VW doesn’t appear to have a great deal of motivation to push Quantumscape forward in commercializing a quantum jump in battery tech. So here’s hoping that one or more other companies develop a similar tech, and make development of the solid state battery a real competition!

Specifically related to Quantumscape, do not expect a product anytime soon. Solid state batteries have a number of fundamental challenges that are no where near being solved.

This company is filled with Stanford grade hot air (think of all the products using any Yi Cui or Fritz Prinz ‘innovations’…I’ll help you – zero).

No product specs after $200M+ in funding and 5+ years of operation point to the truth. See recent article on Quartz regarding the only real value that Sakti3 had was their equipment. Quantumscape is no different.

As Goldman Sachs pointed out, the existing battery tech will probably win the ground for 5-10 years before we can start seeing any new battery technologies. The factories are expensive to build and when built they will have to get the investment back, so a new investment for every new tech would be hard to do.

Mean while we have to watch simple improvements on existing battery technology. One of these is nanosensors that measure the state of charge, and state of health in real time. It is being prepared for volume production at the moment. It is said to give 25% longer range, higher safety and shorter charging times.
