VERY old technology.
Low energy density.
Very very very very rugged indeed.
Beat them to a pulp, spark discharge, generally abuse. Survive.
They were traditionally built in metal can with filler caps, bus bar
interconnections and wooden crates.
Traditionlly wet electrolyte KOH

We had some at school long long long ago that had been salvaged fron a
rubbish tip by the head Physics teacher.
They gave stirling service.


HIGH self discharge
Low energy density.
Very very long life.
Very tolerant of abuse.
Being made and developed
Scale well (safely [tm]  parallel mixed sizes).


Expect to see more of them.
