A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.
We hear about a new battery chemistry like every week. Do most never get to commercialization?
They mostly these articles are showing new avenues for research. Most are deadends usually due to issues with production/scalability.
Sodium Ions batteries are coming to market, however the issue is that Lithium Ion are just improving faster and making it harder for Sodium Ion batteries to compete.
R&d on these I’m guessing takes a little while. And it greatly depends on what niche they fill. Like the poster above said these might have lower density. For applications that move, that’s not usually good. How sensitive are they to hot and cold? That could necessitate thermal management.
One in ten of chemistries in the lab work in real world conductions. One in ten of those are cheap enough to consider production. One in ten of those can scale up to mass manufacturing. Most research works like that. You have to keep going until you hit jackpot.
Its that way with many technologies. The lead time on such research is long enough that market factors alter the viability by the time it is ready to get commercialized.
Quite often innovations from prototype technology can be transplanted into existing tech for part of the benefit, without having to build new production capacity. So the new technology does not commercialised, but the learnings from it does.
probably too expensive and inefficient. LI-ion is pretty efficient compared to NA-ION.
Li-ion technology has huge factories behind it, so economies of scale apply here. The first Na-ion battery factories have just started, so everything is more expensive to manufacture on a small scale. However, the ingredients are cheaper and easily available. Once they ramp up production, we can make a fair comparison between the two.
I have a feeling LIBs are going to be more expensive, but they won’t disappear since high energy density is very handy in mobile applications like cars and phones. NIBs are probably going to end up being a lot cheaper, which should make them a popular option in all the less demanding applications, like grid energy storage, kitchen scales, and anything in between.
at room temperature, but in the real world, where it gets cold, sodium batteries have an advantage.
