Musk Talks Batteries

Musk sounds pretty bullish about battery storage...

Re: Musk Talks Batteries

We know that the batteries are the achilies heal with storage that kw/kg matters when lifting it to mars which is all the more reason to learn how to make even crude batteries from the easiest of obtainable materials until we can refine the materials to make a better quality means of power storage. Hand in hand goes power generation which is constrained by the same reason of getting it to mars.

Re: Musk Talks Batteries

I think kbd512 did create or asked about lithium polymer (plastic) batteris but can not seem to find it...

Re: Musk Talks Batteries

There are many topics which include the word battery or (in this case) batteries

I thought this topic might be a good fit for an article that appears to have started from a Musk quote ...

https://www.yahoo.com/finance/news/tesl … 34016.html

However, not all is lost for domestic manufacturing in the United States. “The good news for building local LFP manufacturing is that the supply chain is simple: Outside of lithium, it's iron and phosphoric acid, two cheap materials already made [in the U.S.] in large quantities,” Jaffe added.

In the end, it is not a question of one battery chemistry versus another. What’s more likely is what we’ve already started to see from automakers, including Tesla: Iron-based batteries will be used predominately in entry-level and cheaper vehicles, while nickel-based cells will be used for higher-end and performance cars. Many consumers will likely be content with a 200- to 250-mile-range vehicle that's thousands of dollars cheaper than one with a range of 300 to 350 miles.

Automakers have also begun making moves to take control of the battery supply, whether through vertical manufacturing or joint ventures with established battery companies. That means that growing LFP capacity in North America and Europe is not only likely, but inevitable.

The article at the link above offers analysis and forecasts for battery chemistries related (primarily) to automotive applications.

Re: Musk Talks Batteries

The issue for Iron use is the scale of the battery to make is that of a building and does not lend to use in a vehicle.

Liquid electrolytes are fine for most earth applications but for mars they would tend to become froze unless well insulated from conduction from its surroundings which it could be in contact with.

The giant Tesla lithium-ion battery that French Neoen is building in the Australian province of Victoria is burning, according to the fire and rescue service of the province.

"A 13 tonne lithium battery in a shipping container is fully involved with crews wearing breathing apparatus working to contain the fire and stop it spreading to nearby batteries," Fire and Rescue Victoria reported earlier today, adding that there was no threat to local residents or drivers despite the release of smoke at the sight.

Every technology has it's risks.

Of all the "battery" topics, this one seemed (to me at least) the best fit.

Re: Musk Talks Batteries

File under “energy facility fires”.  It’s a huge file.

Re: Musk Talks Batteries

It would have been sensible to build these battery facilities with brick or concrete fire walls in between battery units, to limit the potential for fire spread.  It wouldn't add very much to the cost.  It was a poor design decision to cluster these units closely together without any passive fire protection.

Re: Musk Talks Batteries

These are built into what appear to be metal conex boxes but to stop fire spread the units need quick disconnects and more space between them to stop spread or chain reactions from occurring.
