I think that eventually we will see Z batteries in virtually every EV in China because it will become the standard for the industry.
Think about it. Since it has a lifetime warranty, the battery need NOT be owned by the car owner: it will be like buying fuel. One can either plug it in at the house, OR swap out at any of the numerous swap sites, and in order for the swap sites to be economical, they must standardize the batteries.
And when we have the BEST battery by far, it will become the standard.
Think about it...
