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.
Not to mention from a human rights perspective, it’s not just easier to obtain sodium than lithium but also more humane.
There is an industry for ethically-sourced materials, and even if this doesn’t completely replace lithium it can still significantly reduce the amount needed to meet demand, which can also encourage more ethical practices in that supply chain too, such as sourcing it from areas with stronger labor laws.
To bad the market doesn’t care about human rights
That’s why sodium ion batteries are good. The market only cares when it effects their bottom line, and a few more years of development should see more Na+ battery market share
