Bateri (Jawi: باتري) merupakan alat bateri yang terdiri dari satu atau lebih sel elektrokimia dengan sambungan luar kuasa yang diberikan kepada alat-alat elektrik seperti lampu suluh, telefon pintar dan kereta elektrik. Apabila bateri membekalkan tenaga elektrik, terminal positifnya bertindak sebagai katod manakala terminal negatifnya bertindak sebagai anod. "Anod" ini merupakan sumber elektron yang akan mengalir dan menghantarkan tenagakepada alat luar yang disambun…
