I think you may have posted on the wrong thread - however your apparent boundless enthusiasm for Na ion batteries deserves a response.

The thrust of research in battery tech is to produce a smaller lighter safer battery which charges quickly and because it is smaller and uses less, is cheaper. Going sodium is contra all of those goals.
Sodium ion may have a place in fixed storage (mainly because physical production process is similar to and replaceable by Li process) - but it will have to compete with flow batteries (say Vanadium), and pumped storage, and Vehicle to Grid (V2G) etc.

For EVs the thrust will always be towards advanced Li - expect graphite to be partially replaced by silicon (5x more ion adsorption capacity) and for niobium (which has remarkable electronic properties, including superconductivity) to modify the behavior of both cathodes and anodes.
I have said before that EV battery tech is at about Ford Model T stage - just as automobile design advanced to Mercedes SSK level in about 10 years, so too will Li battery tech and design.

Having said that, what comes out of left field always shocks - including the use of Lithium in thermonuclear devices - which may well have been called lithium bombs, not hydrogen bombs. - you can google.
But don't worry, your EV is not going to fission - just burn atm.
