How to use anode in a sentence
The cathode and anode sheets each have one skinny “tab” that connects to the positive and negative terminals of the battery can.
In a cylindrical cell, long sheet-like anodes, separators, and cathodes are sandwiched, rolled up, and packed into a cylinder-shaped can.
They can stab the separator that keeps the anode and the cathode apart.
To make a more powerful battery, Dasgupta’s team and others are looking to change the anode.
By replacing a graphite anode with lithium metal, the battery might be able to hold five to 10 times more charge.
On the anode side, purple permanganate ions are seen rising toward the positive electrode.The Elements of Qualitative Chemical Analysis, vol. 1, parts 1 and 2. | Julius Stieglitz
The plate where the current goes in, the anode, A (Fig. 247), loses in weight since some of the silver is dissolved.Physics | Willis Eugene Tower
It is best to use a fine silver anode, so that the solution, does not get contaminated by copper.
If the area of the cathode exceeds that of the anode the solution is said to grow weaker, and vice versa.
As the masses grow towards the anode the defect naturally tends to increase of itself, hence the necessity for care.

Scientific definitions for anode
The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply.
The positively charged element of an electrical device, such as a vacuum tube or a diode, to which electrons are attracted.
The negative electrode of a voltaic cell, such as a battery. The anode gets its negative charge from the chemical reaction that happens inside the battery, not from an external source. Compare cathode.
