The world we live in today runs on batteries. But the lithium ion batteries that dominate the market are expensive and environmentally demanding to extract. The raw materials for lithium ion batteries are scarce and concentrated in a few geographical regions. This places continued pressure on supply chains.
Also, the sodium batteries, while less energy dense, won’t ignite like Li. Good for home and utility storage, also they have many more cycles IIRC
Also while while i won’t hold my breath on if sodium becomes a thing this would kill two birds one stone by having some use for all the sodium created by water Desalination plants making them more sustainable to run as they could sell the sodium vs creating brine areas in the ocean that kill all the sealife.
Fingers crossed, friend.
