A fact lost on many people, even "analysts" who should know better.You could never compare battery metals to oil in the first place. Since they can be reused even if different chemistries weren't available.
As long as Indonesia is not stripping any Chinese company of ownership in existing mines, I don't really see the problem.
It's up to Chinese companies whether or not they want to invest in new projects of under 25% ownership.
Frankly, this is almost not worth talking about, because nickel's importance in batteries is going down by the day.
the so called overcapacity in China is an overcapacity of foreign legacy ICE capacity.
Electric cars should be much cheaper to manufacture in the long run. Less moving parts and less parts total.
Much of the cost is in electronics but the price for that goes down all the time.
As battery production ramped up the cost of materials also went down as new mines go online.
