We already have an enormous electrical infrastructure. How many houses do you know without electricity? It is gasoline that has poor infrastructure support, who has a gasoline pipeline to their house?Sodium-ion batteries have the same disadvantage of being low energy density and requiring an electrical infrastructure. Plus I'm pretty sure they weren't commercially practical.
The replacement of gasoline is inevitable, even without new battery technology our electrical grid is already there and not going away. Besides electricity, natural gas may compete for awhile but electricity will win in the end.
Not needed, just inevitable.But you are basically admitting that a new battery technology is needed.
