RE:RE:Read them both.I like this part because Elon wants to get away form cobalt and has said he wants nickle companies to ramp up production.
The cathode developed by Manthiram and his colleagues sidesteps cobalt by increasing nickel content; it makes up 89 percent of the metal in the cathode by weight. Their cell combines the ingredients of NMC and NCA cathodes to create a cobalt-free NMA (nickel manganese aluminum oxide) cathode. Although the team is not the first to develop a cobalt-free or high-nickel cathode, Manthiram says it’s the first one that doesn’t also have major performance drawbacks like short battery life and low energy density.
