Well, at least if you buy a Tesla, you're not supporting big oil companies like Exxon — oh wait...
"Oil major Exxon Mobil (XOM.N) is in talks with Tesla (TSLA.O), Ford Motor (F.N), Volkswagen (VOWG_p.DE) and other automakers to supply lithium, Bloomberg Law reported on Monday citing people familiar with the matter."
There’s efforts to make Li-ion batteries recyclable and there’s also efforts to have sodium-ion batteries as an alternative to Li-ion. I’d also like to see more discussions for nickel–iron batteries for stationary storage for solar/wind buffers.
