Seem to be more safe in terms of fires too.
Very similar to lithium batteries in terms of manufacturing, with same compounds, except, well, lithium, so production can be sped up fast.
Even if they won't become a viable option for cars, it would be great for solar shit, which will reduce demand on lithium which will make it cheaper to have more lithium batteries in vehicles.
Also, where tf chinks from aliexpress got them? Mass production test run got recycled by selling to random dudes?
