Question: What do we currently use for our batteries and why do you think that the sea's materials would be better?

Currently we use Lithium sources that have to mined from places like South America and Asia. The issue is now that we’ve mined these so much that they’re running out in the earths crust and are getting more and more expensive. What I’ve been working with are Sodium ion based batteries which is almost infinitely available in the earth and the sea. As the earth is predominantly sea water the sustainability is much much better. Sodium ion batteries store slightly less energy per gram of material than lithium ion batteries due to the increased ion size which makes them not so good at things like micro electric circuitry but for future applications like storing grid electricity to cater for a countries electricity grid sodium would be perfect. There’s alot of scope for both but there has to be an interest in sustainability and future longevity of the ideas we come up with.
