Definition of cathode in English:

cathode

noun ˈkaθəʊdˈkæθˌoʊd

1The negatively charged electrode by which electrons enter an electrical device.
负极，阴极。ANODE 的反义词
The opposite of anode
Example sentencesExamples
- Oxygen enters at the cathode, where it combines with electrons and is split into ions that travel through the electrolyte to react with fuel at the anode.
- The fact that identical electrons were emitted from cathodes of a range of materials under a range of conditions strongly suggested that the electron is a fundamental constituent of all atoms.
- Those same ions would then flow to the cathode, and after electrons were added, would end up as pure copper.
- The opening focuses the electrons emitted from the cathode onto the anode to a spot size preferably less than 40 nanometers.
- An electron originating near the planar cathode and ultimately collected at electrode A will induce an equal charge at A and B during most of its journey.
1. 1.1 The positively charged electrode of an electrical device, such as a primary cell, that supplies current.
  （原电池等的）阳极
  Example sentencesExamples
  Therefore, in electrolytic cells, the cathode is the negative terminal and the anode is the positive terminal.
  The electrons on the anode migrate via a wire to the cathode, the other electrode in the fuel cell, where they are electrochemically assisted to combine with the protons and produce hydrogen gas.
  But because electrons must be supplied to the cathode by an external power source to drive this process, the cathode in an electrolytic cell has a negative charge.
  Most fuel cells use a polymer electrolyte membrane to separate the cathode and anode.
  The trouble with the fuel cell is that it requires a barrier between the anode and the cathode because the oxidizing and reducing agents will corrode catalytic elements if allowed to intermix.

Derivatives

cathodal

adjective

Stimulation parameters consisted of 0.5 ms trains of rectangular, cathodal pulses, 0.1 ms in duration, provided by a constant-current amplifier.
Example sentencesExamples
- In all experiments, the anodal and cathodal solutions were identical and comprised 10 mM Tris buffer at pH 6.3 or pH 8.5 together with additional electrolytes as described below.
- The genetic interpretation of the relative mobility for the observed bands led us to assign an ‘a’ to the most anodal allele, and a letter following the alphabetic sequence to each subsequent cathodal allele.
- Two different regions of activity were identified for DIA, from which only the most cathodal was consistently interpreted.
- Interestingly, one sample had increased polyclonal, cathodal IgG, probably of the IgG, subclass; the AMCVs for this sample were relatively high (and higher than those for most IgG MC).

cathodic

adjective kəˈθɒdɪk

Researchers determined the optimum potential for switching the photocurrent to be - 0. 05V, where the anodic and cathodic photocurrents are about the same.
Example sentencesExamples
- There are three broad classes of corrosion-inhibiting admixtures, using different chemical mechanisms to control oxidation and the resulting corrosion - anodic inhibitors, cathodic inhibitors, and organic inhibitors.
- Stainless steels are positioned towards the cathodic end of the galvanic series in seawater.
- Welds made with these electrodes are cathodic to the base metal and thus resist galvanic corrosion.
- Although the actual chemical reactions taking place within a battery are very complex, the major cathodic and anodic reactions can be idealized based on a knowledge of the parts of a battery and their electrochemical function.

Origin

Mid 19th century: from Greek kathodos 'way down', from kata- 'down'+ hodos 'way'.
