Wow, really?
I've got dozens of Li-ion batteries in my house and only two lead-acid. One in my truck and one I use as a backup power supply for my radio equipment.

Lithium Ion attached to a supercapacitor with a sophisticated BMS is a much more complex setup-- yet even so, it will probably end up being the gold standard in the long run at this point, I would say even in most places lead-acid is still being used. I would not have predicted anything like that even five years ago, but barring some unlikely breakthrough it seems like where we're headed.
