阴极

锌铜电池之铜阴极
伽凡尼电池

阴极(英文:Cathode)是发生还原反应的电极,相对于阳极为其对立面。

在放电的电池中,阴极为正极。正极指电源中电位(电势)较高的一端。电流的方向为从正极流出,从负极流入。但是实际上电子的方向却与电流方向相反,电子从负极流出,经由电路,到达正极。

阴极经常与负极混淆,甚至在大多数英汉词典中,英文单字Cathode也被翻译成负极。事实上,只有在电解池中,阴极才与负极相关联。而在电池中,阴极是负极相反的存在,即正极。

A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition is sometimes remembered using the mnemonic CCD for cathode current departs. A conventional current describes the direction in which positive electronic charges move. Electrons have a negative charge, so the movement of electrons is opposite to the conventional current flow. Consequently, the mnemonic cathode current departs also means that electrons flow into the device's cathode.
