VW solid-state battery retains 95% capacity over 1,000 charge cycles in lab testing

He's right, big economies still generate power by burning coal; you need to change this first. The extraction of lithium, cobalt, etc. also degrades the environment.

I see that companies should have focused on developing sodium batteries years ago.
I am not seeing any evidence that ICE engines are more efficient then power plant electrical generation, even including coal burning:
I am certainly no expert, but everything I have read says they aren't.
 
Incorrect - back at you ;) Power plants don't convert fossil fuels directly into mechanical energy like an ICE. The power delivery chain for a EV is: Power Plant burns fuel = heat energy -> turbine = mechanical energy -> dynamo -> grid transmission -> charge battery, then discharge battery = mechanical energy. Every step has losses that amount to far more than those in an ICE.

As I have said in another comment, I am certainly no expert. It's just everything I have read has essentially stated that power plant generation is more efficient than ICE.

You don't need to be an expert to know that if the goal is to reduce pollution, we must stop burning coal to generate energy first, and secondly, depend on toxic, rare and controversial metals such as lithium, cobalt and nickel.

Sodium batteries seem like the best alternative in this case.

Agree on the batteries, but my only point was that EV are more efficient that ICE engines even when coal generation is taken into account. Pollution is a different topic, but according to the EPA at least, EV is less polluting. https://www.epa.gov/greenvehicles/electric-vehicle-myths
I have never seen any concerns about the toxicity of lithium, cobalt or nickel. I have read about how those elements are acquired and the amount needed can be problematic.
