anode
IPA: ˈænoʊd
noun
- (electricity) An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows inwards (and thus, electrons flow outwards). It can have either a positive or a negative voltage with respect to cathode of the same polarized device (depending on whether the device is a load or a source, respectively).
- (chemistry, by extension) The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode.
- (electronics) The electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube.
- (electronics) That electrode of a semiconductor device which is connected to the p-type material of a p-n junction.

- Note that here the user is interested in the function of heating water and the anode is a component that can help to do this.
- The electrical storage capacity of a Li-ion battery is limited by how much lithium can be held in the battery’s anode, which is typically made of carbon.
- A sheet of copper, termed the anode, is then placed within the tank, parallel with the surface to be plated, known as the cathode, and so mounted that it may be adjusted to or from the iron surface, or cathode.

- On the other hand, it was found that in the silver coulometer when the anode is wrapped with filter paper (as it always was in the earlier researches), too much silver is deposited, or at least the total weight of the precipitate is too large.
- The MIT report explains that in a traditional lithium-ion battery, the lithium ions flow between a negatively charged anode, which is usually graphite, and the positively charged cathode, which is usually cobalt oxide or lithium iron phosphate.
- However, he was able to compensate somewhat for his lack of a classical background by his correspondence with friends, like William Whewell (who, for instance, suggested the terms 'anode' and 'cathode' rather than Faraday's original 'eastode' and 'westode), and the mathematical formulations would come later with Thomson (later called Lord Kelvin) and Maxwell.
