You do realize that electric cars have been around for a very long time, don’t you? Some countries even have battery powered buses. By going this thin, the surface area of the anodes and cathodes become huge compared to traditional batteries of similar volumes.

You still haven’t addressed the basic issue...its the chemicals that contain the ions that need to be greater in size...not the anodes and cathodes. Thats why you can’t downsize the batteries.
