How did Luigi Galvani’s frog experiments contribute to the development of batteries?

Luigi Galvani’s experiments with frog legs were instrumental in the development of the battery, primarily by providing the stimulus for Alessandro Volta to investigate the source of the observed electrical effects.12

In the 1780s, Galvani observed that the legs of a dissected frog twitched when touched by metal probes, a phenomenon he attributed to an innate "animal electricity" residing within the tissue. While Galvani’s conclusion regarding the source of this electricity was incorrect, his observations sparked a significant scientific debate.132

Volta, skeptical of the "animal electricity" theory, argued that the frog’s legs were merely acting as a conductor and an electroscope for electricity generated by the contact of two dissimilar metals. To prove his hypothesis, Volta began experimenting with metals alone, eventually discovering that animal tissue was unnecessary to produce a current. This led him to invent the voltaic pile in 1800, the first device to provide a continuous source of electric current. Thus, while Galvani’s work was based on a misunderstanding of the biological mechanism, it served as the essential catalyst for the invention of the modern battery.132
