A massive underground deposit of high-grade phosphate rock recently discovered in Norway is big enough to satisfy world demand for fertilisers, solar panels and electric car batteries over the next 100 years, according to the company exploiting the resource.
Phosphate probably isn’t going to be used in batteries for long. Probably better than using an ICE car still and other emerging battery tech will soon replace it. BYD has started shipping sodium-ion batteries, for example. They’ve decided range is already sufficient I guess and price is a more important factor for consumers. That they are also more environmentally friendly is also great and hopefully part of their decision. There’s plenty of other battery technology on the near horizon that doesn’t use phosphate though.
I think solid state batteries are going to be the way forward, once that gets nailed down.
