This may be the only downside. The new sodium-ion battery weighs 350g (about 12.3 oz.), which is about 1.5 times heavier than an equivalent lithium-ion battery.
And that’s why I said it’s not happening. These batteries are far too heavy for cell phones. That’s an increase in weight I would gladly accept, but I don’t expect it to catch on.
Most of the weight in a phone is from the battery so to get an idea find a second cellphone and hold it with yours and that is the new weight. Ironically my cellphone is only 170g. Meaning that just the battery from your article is 2x the weight of my phone. I would gladly carry that for the increased battery life alone, but many will not.
Hope I’m wrong though and we do adopt it, or maybe they figure out how to make these batteries even lighter.
That’s great for grid storage. Maybe one day for even EV use, emphasis on maybe. But you’ll never have a cell phone with a sodium battery
where do people get their science.

That day is already today. They need better density for digital devices, probably, but with all these advancements, who knows.
