The weakest link in EV is the Lithium-Ion battery. Remember Lithium-Ion battery used for all electronics (mobile phone, laptop, watch, IoT devices), not just EV. Is it sustainable? Is it affordable? Major components are lithium, cobalt, nickel, manganese, graphite. All have concerns. Most people are short-sighted and selfish. It works today. It's affordable today. Who cares about tomorrow? If in future because of scarcity of raw materials, EV battery costs 500K, only rich can afford it. Do you care now or happy happy with your EV today can oreadi? Same for mobile phones, laptops, when the battery costs 50K, who can afford? Also create geopolitical tensions among countries who have the raw materials (cobalt-Congo, graphite-China) and the countries who need to buy these raw materials from them. Remember what happened to petroleum? OPEC realised they are a cartel and jacked prices up. That was the end of the cheap petrol era. Waiting to see when China, Congo jack up prices and hit the Western world with sky high prices. You want affordable (not cheap) battery, better friend friend China, etc.
