World-first Na-ion power bank has 10x more charging cycles than Li-ion | PCWorld
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.
I would imagine more safety standards would go into energy grid storage. A lot more liability for a company if their product burns down a power substation than a random house or two.
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.
