Tesla battery patent = Titanium Powders
Tesla patent could be secret behind million-mile EV battery:
"The paper shows that the single crystal cathodes that Tesla wants to use degrade a lot slower, resulting in batteries lasting many more cycles – potentially up to 4,000. Additionally, the cathode is currently being manufactured with nickel, aluminium and cobalt, however the paper strongly suggests that the cathode can be made using only nickel and aluminium. This effectively means going cobalt-free, and therefore cheaper.
We know Tesla is keen on going cobalt-free to avoid using up the limited reserves our planet has, and to refrain from getting involved in illegal child labour that some cobalt mines have been accused of taking part in.
The only issue is that this crystal now needs the right additives for it to be incorporated into Teslas. What is promising is that Dahn and his team are already working on a Titanium-based coating that could make a battery that lasts 1.6 million kilometres, or a million miles. The era of cheap, durable EV batteries could be just around the corner."
