There are many alternatives of Li-Ion batteries such as Na-Ion, K-Ion, Hydrogen Fuel Cells, Zinc based RFBs etc.
But like lithium what is the most promising alternative source of electric energy for vehicles? and Why?
1. There are many alternatives using the intercalation principle, but with other alkalines. Among the most promising and developed ones belongs Na-ion.
2. There is no better material for batteries than lithium. Among the most promising rechargeable batteries, containing metallic lithium, belongs Li-S. A research in Li-S is exponencialy rising since 2007 and currently there were some breakthroughs and some research teams / companies claims they achieved specific energy around 500 Wh/kg ( check Oxis Energy).
Fuel Cells
Because, Well hydrogen produces water as a byproduct, it’s exceptionally efficient and it’s much cleaner than lithium when it comes to producing it and recycling it at the end of the life.
Its an option but in my opinion this cannot be the substitute of Li-Ion.
