anode
阳极,阳电极,阴极,阳性
Definitions
- 1
- : the electrode or terminal by which current enters an electrolytic cell, voltaic cell, battery, etc.
- : the negative terminal of a voltaic cell or battery.
- : the positive terminal, electrode, or element of an electron tube or electrolytic cell.
Examples
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.
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.
They can stab the separator that keeps the anode and the cathode apart.
On the anode side, purple permanganate ions are seen rising toward the positive electrode.
The plate where the current goes in, the anode, A (Fig. 247), loses in weight since some of the silver is dissolved.
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.
