> This seems unlikely. There were major industrial and military uses for rechargeable batteries throughout the 20th century.
But there are non-rechargable batteries. Zinc-air batteries have around 600 Wh/kg energy density (3 times more than Li-Ion) and they could have been manufactured with the technologies of the early 1910-s.
Zinc-air batteries can't be recharged in the usual sense, but zinc oxide can be reworked into the metal form easily.
