Battery Question!?

Question

http://www.duracell.com/oem/Pdf/others/ATB-full.pdf

On page 4 of this website, the diagram shows a cathode and anode current collector. How is this possible when current flows in one direction? Also which way will electrons travel when its supposed to travel in the opposite direction of the current. Please explain. Thnx!

Also why is current traveling in the anode(negative) direction. I thought current traveled from positive to negative?

Are you referring the external circuit to wires and the medium to salt bridge?

Answer 1

There is only one thing to remember: Oxidation occurs at the anode. whether the cell is voltaic (battery, electricity producing) or electrolytic (electricity comes in from outside to do something).

If the oxidation occurs at the anode, then reduced species (a metal?) loses electrons and goes into the cell medium as anions. The electrons it lost flow from the anode through the external circuit to the (by a process of elimination) cathode. At the cathode, the incoming electrons reduce something.

Answer 2

In a battery (D.C.) driven, electrical circuit, the "ACTUAL" flow of Electrons is from the Positive (Anode) to the Negative (Cathode).
However, there is also, what is called a "CONVENTIONAL" flow from the Cathode to the Anode and is often indicated in a diagram of a battery circuit.

Answer 3

Number 10 hearing aid batteries because the cages are so tiny, there is barely enough room for the hens.

Answer 4

D.C. current travels from - to + . an example to fact; lightning is
caused by a build-up of electrons ( - charged particals ) They are
attracted to protrons ( + charged particals ).
