Oohhh, experimental groundbreaking paradigm shifting revolutionary battery design article #3646263859!

Let's see if this one isn't total bullshit like the 3646263841 ones before it!

Seriously this is getting ridiculous, I've seen these some literally 40 years ago, 99.99% is bullshit, and now I'm seeing literally over 5 new articles per week.

ITS BULLSHIT.

Call me when there is an actual battery based off peer reviewed research that has been successfully tested in production systems by at least 5 major companies. Until then, BULLSHIT.

While everybody was busy writing bullshit hype articles, we actually got a real revolution with the sodium-ion battery, which you can buy today. It won't replace Li-ion in terms of energy density, but it's much more robust, cheap, handles low temperatures, deep discharge and much more charge cycles, making it ideal for off-grid-storage.

I really wish we had tech news that just reports on stuff that's tested and available for purchase. Things do actually keep improving, but it's completely drowned out in all the other hype.

And it's more ethical and environmentally friendlier than Lithium-Ion, right?

Norway has just started a deep sea excavation for cobalt and copper which as I understand (I'm clueless) can be omitted from sodium-ion batteries. The excavation is roughly of the size of equador and will take place in an area that may contain previously unknown lifeforms and critically endangered eco-system.

A paragraph of an article seems to show their non-chalance regarding the ecosystem impacts and unknown side-effects:

"The Norwegian government recognizes that it can’t be sure any mining would be sustainable—it’s not been able to determine the likely environmental impact of extracting minerals in its waters, nor exactly what minerals are there to be found. “We do not currently have the knowledge needed to extract minerals from the seabed in the manner required,” says Næss."

These are the guys whose grid runs on 99% hydropower but they keep drilling for fossile fuels and now rare earths to export them and in addition are still hunting whales.

So to summarise: I'm very happy that there seems to be an eco friendly battery where its main component is the overambundantly availabe sodium. And the short wikipedia entry seems to reflect, that it's a more simple tech.

The amount of metallic sodium we need for these purposes dwarfs compared to what we're using directly as NaCl, that is, table salt, not just in food but primarily industrial processes. Which again dwarfs compared to what we have available (vaguely gestures at the oceans). Sixth most abundant element in the earth's crust and conveniently most of it is in the form of huge contiguous dried-up oceans buried somewhere.

Thinking of it should become standard practice to actually use the salt that's accumulated when desalinating to get drinking water, lots of issues with locally increasing the salt level in the ocean even though on a large scale the change in salinity is absolutely negligible.
