anode

(ăn`ōd), electrodeelectrode,
terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit. In most familiar circuits current is carried by metallic conductors, but in some circuits the current passes for some distance through a nonmetallic conductor.

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.

anode

1. the positive electrode in an electrolytic cell
2. the positively charged electrode in an electronic valve
3. the negative terminal of a primary cell

anode

The terminal on a device that receives current. It may be considered positive or negative depending on the application. See cathode.

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].
