Musk: Tesla Gigafactory will produce cells with “moderate” battery technology improvement over current products

drone giga oct 2015

Tesla CEO Elon Musk was at the AGU Fall Meeting today for the Presidential Forum and made some comments about Tesla’s battery factory under construction in Nevada.

Musk said that the battery cells the company will produce at the Gigafactory in partnership with Panasonic will feature some “moderate improvements” in technology over those in production today. 

Earlier this year, Tesla confirmed that the battery cells it plans to manufacture at the factory will be different from the current ones solely produced by Panasonic for the Model S and X, but this is the first time that the company attached the adjective “moderate” to the improvements.

During a recent earnings call, Tesla chief technology officer JB Straubel said that the company will manufacture different types of li-ion batteries in the Gigafactory and confirmed that Tesla will have multiple lines operating in the facility.

The automaker currently uses nickel cobalt aluminum (NCA) battery cells for its vehicles and its back-up power battery packs like the 10 kWh Powerwall. For the 7 kWh daily cycling Powerwall, the company uses nickel manganese cobalt oxide (NMC) cells, which typically have a longer cycle life, but less energy density.

During his talk at the AGU meeting, Musk said that the technology improvements at the Gigafactory will not be small nor big, but moderate – without specifying any change in chemistry. He then added that the battery industry is generally seeing a 5 to 8 percent increase in energy density every year.

The CEO emphasized that the Gigafactory will be able to produce better batteries over time and that its main goal is to take advantage of the economy of scale, which he said will be “pushed to its limits” with the factory.

While answering questions from the audience, Musk also confirmed that the Gigafactory will feature an on-site battery recycling facility. He compared the battery packs to “high quality ore”:

“it’s way better to mine a battery packs than rocks.”

We recently learned that Tesla’s Gigafactory will be nearly 40% larger than expected and that the company already started production, but only for stationary storage battery packs. Battery cell production is only set to begin in late 2016.

We will update this post with a video of Musk’s talk at the AGU meeting when it will be available.

    Tesla originally stated that the cells produced at the new factory would be 10 to 15 percent better than the ones used in the 85 kWh packs. With the 90 kWh packs probably using 6 percent improved cells that doesn’t leave a lot of improvement to go unless their plans changed.

    What happened to all the solar on the roof? I’m hoping that’s the last thing added vs. not using it at all… Of course they also said many of the SuperChargers would be solar powered and only a couple are (yes, it wouldn’t power many cars, but it promotes a good message & provides needed shade at the chargers). Love the progress though on the Gigafactory!

    If I were them, I’d downplay the cell improvement as much as possible. If they said major improvements, starting this summer, they can close Freemont and reopen it with the GF
