anode

[′a‚nōd]
(electricity)
The terminal at which current enters a primary cell or storage battery; it is positive with respect to the device, and negative with respect to the external circuit.
(electronics)
The collector of electrons in an electron tube. Also known as plate; positive electrode.
In a semiconductor diode, the terminal toward which forward current flows from the external circuit.
(physical chemistry)
The positive terminal of an electrolytic cell.

anode

In an electric system to protect underground iron pipes or structures from electrochemical action, a metallic rod which is driven in the ground; direct current is passed through the rod to the earth, and then through the iron pipe or structure, in a direction opposite to that resulting from the electrochemical properties of the soil.

Sacrificial anode specimens used in this work were magnesium alloy rods with diameter of 10mm.
The CR2016-type coin cells were assembled with sodium metal as the reference electrode, glass fiber membrane as the separator, and the as-prepared CNF-Ti[O.sub.2] directly as the anode. The above procedures were all carried out in an Ar-filled glove box ([O.sub.2] <01 ppm, [H.sub.2]O < 0.1 ppm).
The anode is a copper disc with the thickness 16 mm which is rotating with the frequency 50 Hz in order to assure uniform erosion.

The sacrificial anodes, comprising a zinc core encased in a small, cementitious shell, are installed within repair sites to prevent incipient anodes developing, or outside repaired sites to protect the reinforcement in chloride-infused concrete.
Eric Desaulniers, president and CEO of Nouveau Monde, said, 'SHINZOOM is a well-respected and established anode material producer in Asia.
The smaller dimension structures compared with the bulky silicon have shown several improved characteristics for better electrochemical performances as investigated in the previous research: low-dimensional silicon anode materials maintain larger surface area; thus the fast electron transfer and shortened lithium diffusion pathway would be allowed for better rate performance; also, the smaller sizes of silicon could provide better accommodation with volume changes for better electrochemical stability [31-39].
By coming up with a material that is several times thinner and lighter than traditional graphite, carbon or silicon anodes, the company managed to shrink the battery size by half, without sacrificing the power's longevity.
