We hear about a new battery chemistry like every week. Do most never get to commercialization?

the strategy of retaining crystal interlayer water yielded a specific capacity of 280 mA h g−1 at 10 mA g−1, one of the highest capacities reported for SIB cathodes in literature.

All I could find. This isn't a statement about capacity(?) Units are wrong(?)

Its worth noting how preliminary this research is. Currently these "batteries" are just jars with chemicals.

And instead of charging them, you can drink them! Unlike Lithium Ion batteries, which you have to chew.

There is also the issue with the salt by itself in desalinisation. If it's removed with water, you have to deal with that stuff. Table salt is really cheap and there is plenty of offer,, so you can't really economically clean it enough and package it for human consumption or industrial use. So what usually happens is that they dump it back at one moment or another. And that is a hard pollution, and can lead to dead zones around the desalinisation plants if not managed well enough. Being able to add it in a high demand product such as batteries takes all those hurdles away

Yes, because battery technology stagnated years ago...

Oh wait

I can only hope one day people will stop repeating reddit clichés

Sodium-ion batteries are not hype though, they are in production use in multiple industries already. They are generally superior to Lithium based batteries in all regards, with the exception of having a bit lower energy density. An equivalent LiFePO4 battery might be 70-80% of the size for the same storage. It's not a big deal for large applications like cars and solar storage.

To answer your question we'll need to conduct a series of electrical tests on your left ball. Please report to the lab as soon as possible, and wear loose pants.

Compared to a non-hydrous sodium vanadium oxide system.

We are close to finding out why some liquids are blue.

You can throw any battery in the ocean. The better question is should you?

Would you prefer researchers to not publish results?

Yeah I'll take this seriously when it enters commercial service.

i’d say stability is more important than energy density

like gasoline has more than 10x the energy density than tnt and we’re perfectly fine with many kg of that on a vehicle going 100km/h

a fully fueled vehicle is the equivalent of ~600kg of TNT, but it’s very stable whilst TNT is not

Yeah but firewood is like 5 kwh/kg, or 4 times the energy density of TNT. We drive around with wood in our cars all the time.

TNT has 1162 Wh/kg ratio.

How do you recharge TNT?

We are hitting the limit what is doable with energy density.

I mean, we're definitely running into a problem of how you build a battery without also building a bomb. But the entire point of TNT is rapid thermal expansion. The point of a battery is very low voltage steady release of electrical charge.

I might also note that C4 has around 6 Mwh/kg. A bit of applied chemistry can go a long way to improving energy efficiency. And that's before you take advantage of geometry to focus pressure, via a shaped charge.

Point being, there's a lot of clever ways to juice a lemon. We're a long way from the end of the road on battery improvement.
