Also, the battery pack for a cell phone 30 years ago was about the same volume and weight of an entire smartphone, with a capacity of about 500 mAh. They are also far cheaper if you account for inflation.
Batteries have improved incapacity by about a factor of 10 and the cost per watt-hour has reduced by about 99% in the last 30 year. All without a single advancement in the technology, apparently.

I wouldn't call it a single advancement but hundreds. The materials might be largely the same but manufacturing is huge. When you roll up some metal to make a battery then increasing the number of layers is a huge challange when they're already tiny.
What do you mean by that?
I would say there have been a great many advancements in technology. I mean, that's what all these improvements are, right?
It was sarcasm, which seems to be harder to convey in text than any number of battery advancements.
