    Pilar elektrokimia modern dipandang berasal dari tumpukan kerja percobaan yang dilakukan oleh Alessandro Volta pada tahun 1800. Meskipun jauh sebelum masa itu, berdasarkan bukti arkeologi, telah dikenal baterai primitif (disebut baterai Baghdad) yang digunakan untuk electroplating di Mesopotamia pada tahun 200 SM. Volta terinspirasi oleh percobaan kaki katak yang dilakukan oleh Galvani, yang meyimpulkan fenomena…

    Baterai adalah salah satu alat penting untuk penyimpan dan konversi energi yang bekerja berdasarkan prinsip elektrokimia. Jadi, baterai sebenarnya merupakan sebuah sel elektrokimia. Berdasarkan cara kerjanya, sel elektrokimia dapat dibagi menjadi dua, yaitu: sel galvanis dan sel elektrolisa. Sel galvanis, yang juga disebut sel volta, merubah energi kimia menjadi kerja listrik sedangkan sel elektrolisa merubah…
