Sodium ion batteries are better in almost every way, except energy density. They are bigger and heavier to provide the same amount of energy storage. Sodium is available everywhere, cheaper and requires less energy to manufacture, fewer toxic waste components, charges and discharges faster, and lasts longer.
This company is selling 9,000 mah packs for $65-70 depending on the exchange rates, but the prices will come down as more manufacturers join the market.
i think they should focus on stationary energy grid storage applications first. Take advantage of economies of scale to develop batteries on a massive scale. Then, when development is done, cater to the end-user market as a by-product. The end user market requires higher safety standards (you don't want to burn down your house), and so more experience is required.
Imagine if we could swap batteries on the car with these. Daily commute to work in the city? pick the sodium ion version for safety and longevity, lower density but enough for daily errands. Wanna go out for a long drive for camping? switch to a higher density battery without any worry of running out of juice.
I never understood why swappable batteries weren't prioritized as standard in the first place. Decouple charging time from refueling time, and you could be in and out of the service station in minutes. Plus, batteries degrade over time, so a long-lasting car is going to need replacements eventually anyway.
Maybe I will pick one up when I go to Japan. This will be a game changer on the Critical Minerals front if it can be scaled up to more than just a phone charger.
The way I see it, sodium ion batteries look really promising in many applications where size and weight aren’t a huge concern. Obviously, mobile phones aren’t ideal, but bikes and city cars should be fine. Maybe even grid energy storage.
Yeah grid energy storage is the main application as far as i'm concerned.
At first I thought you were self-censoring the word "nation" lol
Na-ion batteries are a good thing. They are made from widely-available resource, thus there is no risk of shortage.
On top of that, they have the potential to get real cheap in the future due to said ubiquity of raw ingredients.
Looking forward to those cheap batteries. It might take a few years to ramp up production, but once that happens, it’s going to be even wilder than it currently is with Li-ion batteries.
Nowadays, we have batteries in a bunch of weird things like earbuds, bluetooth speakers, vacuum cleaners, mice, kitchen scales, and even disposable vapes. When Na-ion batteries get really cheap, we could have even more batteries in everything. This means that all the things that currently don’t use electricity at all, might do so in the future.
Ubiquitous cheap batteries also make renewable energy extremely feasible making a happier future for us all. :)
I hope this tech kicks off asap
Please give us cheap energy storage. That will be a true game changer.
