I'm talking about the fundamental difference between a battery of any variety (chemical, flywheel, etc.) and petrochemical energy sources.
The article compares energy density of gasoline and other energy sources with "electric". It's a poor comparison. These are different categories. One is an energy source which is also a storage medium (single use), the other is a pure storage medium.

Not in the sense that we use it up for energy, but in the sense that if you want to run all cars on lithium batteries there simply isn't enough easily mine-able lithium in the world. In this sense it is valid to say that we mine batteries. The same story goes for most solar panels. Comparing the energy density of gasoline with the energy density of a charged battery is obviously also valid.
