> Massive 20 GWh sodium-ion battery manufacturing plant announced in China
Thanks for drawing my attention to this @deutrino. Even after skimming the article, I'm a bit confused about exactly what it's reporting.
Is the plant;
* using 20GWh to produce batteries?
* producing batteries with a 20GWh capacity?
* producing 20GWh worth of smaller batteries in a production run (eg per month, or per year)?
* Something else?
Can anyone clarify?
This seems like a realistic assessment of the state of solar in Africa.

Remarkable growth in "rest of World" of 242% YoY.

Yes, sooner would be so much better.
OTOH, Lithium BESS has gone from ~100MWh deployed in 2017 to ~92GWh in 2025. so around 1000x in 8 years (and thats not counting domestic behind the meter).
China deployed a 100MWh Sodium BESS in 2024 so by 2032...
Lithium ion batteries can be a fire risk, yes. But cheap ones in household devices (phones, charging packs, *toys*) are much riskier than the ones in EVs, according to Colin Peacock;

Lithium ion EV batteries are probably no riskier than a tank of extremely explosive fuel. Certainly not risky enough to justify a regressive crusade against EVs in general, which these days may have nonexplosive sodium ion batteries.
I've posted a few times in the last year or two suggesting sodium ion batteries as an alternative to lithium ion. Cheaper, safer, longer-lived, and easier to manufacture, and to recyclable at EoL. Mainly for fixed installations at this point (eg storage for rooftop solar), because the tech is new and still somewhat bulky.
I recently visited the friends who introduced me to them, as storage in their off-grid systems. They can't praise them enough.

I've posted a few times about sodium ion batteries, and one of the things I've consistently said is that they're much cheaper than lithium ion;

Well apparently not at the moment. Demand has outstripped supply, pushing the price up, and as demand for lithium ion drops off relative to the well established supply, prices have dropped.

Try to be EXTREMELY mindful when you are getting rid of something or purchasing something casually. The embedded #energy for everything - regardless of how cheap it is - can be mind-boggling.

Toyota confirmed it would put as much as $10 billion into the U.S. over the next five years to boost local operations, after Donald Trump flagged that the carmaker planned such an investment. https://www.japantimes.co.jp/business/2025/11/13/companies/toyota-us-10-billion-investment/?utm_medium=Social&utm_source=mastodon #business #companies #toyota #carmakers #cars #investments #donaldtrump #batteries #electricvehicles
Interesting real world data, on 1GW firm power supply.
Masdar UAE - solar + batteries.
Cost USD 6 billion.
Construction time 2 years (caveat, not sure if this is a tranche or all of it)
Hualong One
Cost USD 3 billion (from actuals)
construction time 5 years
So purely on construction cost, large scale firm solar is twice the price of Chinese nuclear.
Note, fuel, op costs, water needs, llife time, site cleanup etc not accounted for.
Turns out batteries are quite useful.

Batteries at scale are changing a lot of assumptions.
Batteries the focus of Japan's EV market, with domestic automakers adopting lighter, more efficient packs and technologies popular with Chinese manufacturers. https://www.japantimes.co.jp/business/2025/10/19/companies/ev-battery-race/?utm_medium=Social&utm_source=mastodon #business #companies #electricvehicles #carmakers #batteries #suzuki #honda #nissan #china #byd
Chinese battery giant CATL has announced a new Sodium Ion battery pack for EV that is game-changing. It features:
⦁ 10,000 charge cycle lifetime to 85% capacity
⦁ 90% power capability at -40℃
⦁ 175 Wh/kg energy density, behind Li-Ion at 300 Wh/kg
⦁ no thermal runaway danger
⦁ cost $19/kWh, compared to $50/kWh for Li-Ion
This will be ideal for mid-range, low cost EVs, and for grid batteries. They start mass production in 2026.

The thing about batteries (and renewables, but REALLY about batteries) is the sheer volume of research (both in labs, company R&D and deployed) along with the pletora of research directions to choose from.
We are still at the bottom of the hill for battery and energy storage research.
