I wonder what the energy density of 100 year old batteries was.

Here's a battery density graph, there are a variety of these out there but give a good approximate comparison of different types.

Lead acid I believe is what was accessable for automotive purposes 100 years ago.

Li-ion cells have about 50-60 years of research in them with maybe 30 where they've been able to be used in automotive applications.
