We’ve maxed out the potential of lithium-ion batteries, without a new paradigm about them. So, we can’t do anything about the battery itself.
There is work on solid-state batteries may hold some promise of progress. However, the only thing that we can do, which is doable, is deal with lightening the car through new technologies. That is something we can do something about.
Mind you CATL is the world’s largest battery maker of all cells you know the ones in laptops,your smartphone used to type here, tablets, electric power tools and lawn equipment. Medical devices. It’s not just EVs none of modern electronics smart phones in particular could exist without lithium ion batteries. CATL just tripled the energy density and they are not some research queen tech. CATL brings things to market in a big way. The Chinese are kicking the world’s butt with energy technology of all forms especially nuclear power they have 150 reactors in the pipeline to be built, and they are full steam ahead on fast spectrum nuclear reactors. They also have a full reprocessing regime set up. They are decades ahead of the USA in fast spectrum nuclear reactors and reprocessing.
