Baterai ion lithium

Baterai adalah sel elektrokimia (juga dikenal sebagai sel Galvanis) yang merubah energi kimia menjadi energi listrik, yang terdiri atas anoda dan katoda yang dipisahkan oleh elektrolit. Elektrolit adalah penghantar ion yang berfungsi juga sebagai media pengisolasi elektron. Elektron dihasilkan pada anoda dan mengalir kearah katoda melalui sirkuit luar sementara, pada saat yang sama, elektronetralitas dijamin … Continue reading Baterai ion lithium
