I think you don't grasp the directives that are being implemented. The UK is already talking about moving the deadline to EV only sales by 10 years. I expect other nations will do the same, in Europe and possibly Asia.If there are not enough batteries, the solution is simple: don't ban ICE engines.
That will also solve the problem of national security.
I don't believe only EV's will be allowed in the near future, and the target date of 2030 will never be respected.
There are already areas in Europe where they have now already problems as the network cannot transport enough electricity. There are 28 million cars to be replaced. If they have to load only 50Kw every 2 days, the network has to transport 700 million Kw per day extra, on top of what they cannot transport already today. And most will charge after work causing a huge spike.
I have a friend who works in one of the biggest battery recycling companies in the world, this company also produces the raw materials needed to build batteries. There is now already a shortage. The production is already sold before they are produced.
They will have to build batteries with other raw materials then the actual ones.
The switch has been decided and supply problems will be addressed when they occur.
There's no question that electricity supply will come from polluting industries for the foreseeable future, until alternatives are found. But pollution from ICE vehicles will be eliminated and such vehicles will be rare in as little as 20 years.
