Apparently the Oxford Bell batteries were sealed with molten sulphur. I bet that contributes some sulphur acids, but strange to think of it contributing both conductive acids and acting as an insulator.
Perhaps the sulphur releases sulphur dioxide which forms acid with the moisture in the paper whilst the solid sulphur remains non conductive. But there again, I'm reminded of Compact Disc Bronzing and the problems acid paper causes libraries , but both those issues suggest old paper contains enough sulphur of its own to not need the extra provided by a coating. And apparently "cellulose itself produces formic, acetic, lactic and oxalic acids."
I wonder if someone makes a range of metallised cigarette papers? If they sell a silver and Bronze variety you could work up a technique for punching out discs in their thousands and start experimenting Otherwise, some other pair of metallised papers must be out there.
Portable equipment of the Thermionic Age often used HT batteries to supply 150V or so for the valves, and in the early years of atomic research, batteries consisting of thousands of individual cells wired in series were often employed when kilovolts were required on tap in the laboratory.
Finally, effective treatment for Zamboni's piles was probably not available in the early 19th century.

A use for this device might be discovery and testing hitherto unknown uses of paper with the object of improving the printability and/or mechanical aspects of fibre based structural members.
It is amazing that the non uniformity of paper makes every bit different than every other bit made.

I remember as a child saving up and buying an Ever Ready 90V battery that my nearest bicycle shop had on sale for people who still had valve radios, something like this
I was worried that despite the hight price it might have sat there for years and be useless, but it was fine. Made really nice little arcs between copper wires!
Whatever the chemistry in that Zamboni battery is, it has an amazing shelf life. I doubt there'd be much juice left in a Duracell after 160 years!

Me too. Found a 90 volt dry cell in stock at J&H Outlet (electronics and surplus) about 10 miles from home by three-speed bicycle. Needed it for some neon glow lamp blinky circuits.
