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.
Desalinating water might be the best part. Usually, solar power has the downside of needing storage and desalination has the downside of big energy requirements. If you can do both at the same time, it’s a big win for dry climates with lots of sun
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
Could the excess sodium used for carbon sequestration? Sodium bicarbonate is baking soda but I don’t know what it could be used for aside from baking or if the energy to capture that carbon would even be a net positive.
I need a shit ton of salt in winter for my road. But for how long?
I can’t imagine it’s doing this at a rate that will make a big impact on water supply, I suspect this is one of those things they throw in just to have a good headline.
They are not going to get the sodium from desalination, they will mine it because it’s cheaper.
and more pure
Exactly, the desalination gimmick is bullshit for STEM ignorant hippies.
