An electrichemical cell converts chemical energy into electrical energy An electrichemical cell converts chemical energy into electrical energy Alessandro Volta invented the first electric cell but got his inspiration from Luigi Galvani. Galvani’s crucial observation was that two different metals could make the muscles of a frog’s legs twitch. Unfortunately, Galvani thought this was due to some mysterious “animal electricity”. It was Volta who recognized this experiment’s potential. An electric cell produces very little electricity, so Volta came up with a better design: A battery is defined as two or more electric cells connected in series to produce a steady flow of current Volta’s first battery consisted of several bowls of brine (NaCl(aq)) connected by metals that dipped from one bowl to another His revised design, consisted of a sandwich of two metals separated by paper soaked in salt water.

Alessandro Volta’s invention was an immediate technological success because it produced electric current more simply and reliably than methods that depended on static electricity. Alessandro Volta’s invention was an immediate technological success because it produced electric current more simply and reliably than methods that depended on static electricity. It also produced a steady electric current –something no other device could do.
