An anode is the electrode in a battery or galvanic cell where electrons are released and flow out into an external circuit. It matters because it's the source of electrical current that powers devices, making it a fundamental component of how batteries work.

陽極（英語：Anode）是發生氧化反應的電極。相对的，陰極（英語：Cathode）是發生還原反應的電極。 英文anode和cathode是法拉第在威廉·惠威爾的協助下发明的词，anode表示“发生氧化反应的电极”（或者失去电子的电极），相当于中文的“阳极”或“氧化极”。相反的，cathode则表示“发生还原反应的电极”（或者得到电子的电极），相当于中文的“阴极”或“还原极”。
