Sodium ion is coming into it's own. And other battery chemistries are being developed as we post. 25% of autos sold worldwide were EV's in 2025. Now it looks like we will see batteries in more heavy duty applications;

China's sodium-ion truck passes 9,300-mile extreme weather test​

FAW Jiefang, in partnership with Zhongke Haina, tested a 339 kWh sodium-ion battery electric truck over seven months and 9,300 miles, operating in both high and low temperatures, varied road conditions, and under heavy commercial loads. The battery retained more than 90% of its usable capacity at -40°F, a significant achievement for cold-weather performance. With full charging in 20–25 minutes and a cycle life exceeding 8,000 fast-charge cycles, the trial demonstrated the potential of sodium-ion batteries to meet the rigorous demands of heavy-duty transport while offering cost and safety advantages over lithium-ion systems. Interesting Engineering

 
Battery tech is only beginning, EV's will be too economical and reliable to be shut out of the U.S. market for much longer. It appears sodium-ion is eclipsing lithium-ion.

I invested in a battery startup, it was out of New York and had some heavyweight support behind it, including Schumer and the Governor. They also had a consultant who shared a Nobel Prize in chemistry.

After three years, investors gave up on it, and with the money gone, so was this business. And so was my investment. I was not too upset, my lithium mining investments more than covered these losses. I dumped all of those investments before Biden left office, I knew what was coming.
 
GM is building their own now, partnering with Peak Energy. If they are looking for grid storage, it will surely end up in an EV as this tech progresses.



For decades, battery progress has been defined by familiar performance metrics such as better energy density, higher power, and faster charging. Those headline metrics still matter, especially in electric vehicles. But as electricity demand rises and data centers consume a growing share of U.S. power, the battery conversation is changing.

When you’re talking to a utility, a hyperscaler, or other power providers in need of energy storage solutions, their priority is not maximizing range or minimizing weight. It is delivering reliable, affordable power over long periods of time in real-world conditions.

That is what makes sodium-ion battery technology so compelling, and it is why we at GM are developing next-generation sodium-ion battery cells purpose built for grid-scale storage, in partnership with Peak Energy and backed by a strategic investment from our GM Ventures arm.

An aspect of sodium ion that is seldom highlighted is availability. Lithium, while not rate, occurs in small percentages in the brines and pegmatites. So sources are limited. Salt is everywhere, and cheap. Since you can build very good batteries with the main components being sodium and carbon, you have a battery that any nation in the world can build from local materials. And at least one battery manufacturer has made a sodium battery that equals the present ternary lithium batteries. Also, the sodium battery is lighter as it uses no metals like nickel and cobalt.

No question that, resource wise, sodium-ion is far more available and so less labor intensive to extract than lithium, to say nothing of the amount of water lithium mining consumes in its extraction, and this lithium is often found in some of the driest places on earth.

Did I also read there is a far lesser chance of fires with this battery? I believe I did. This is an exciting and emerging new battery technology, it makes me wonder if lithium is on its way to the status of coal as an energy source, meaning still necessary at present, but everyone wants a better source for energy and will be soon on the way out.
