• The electric battery has increased the prevalence of motors and wireless communication in our lives. Electric batteries retain and release the electrical energy they have gained by converting other forms of energy. This traditional variety gains from chemical energy.

  • Essentially, all chemical reactions revolve around how the electrons in the bonds between atoms are rearranged. The bridge between this fact and the electrochemical cells that served as precursors to modern batteries is most evident in the experiment conducted by Luigi Galvani in 1780.

  • In the early 19th century, Michael Faraday figured out why these cells worked the way they did, and named their various components (anode, cathode, electrolyte, etc.).
