Sodium and magnesium to replace lithium in batteries

Hello everyone,

I have been following this forum on daily basis and after reflection bought many Galaxy shares last year...im really convinced in the power of lithium and even more in Galaxy on the long run...im buy and hold.
Before to invest I was wondering if there was any kind of substitute for lithium such as the sodium or magnesium. As I m living in Switzerland (glad to represent Galaxy here ), I found this article:

I haven't any doubt about the reliability of this study as the Swiss National Science Foundation is behind.

I wanted to have your view on this and how it could impact the lithium companies in the long term.

Be long and dont panic, happy GXY holders. Cheers
