Are the terminals of batteries labeled according to electron flow notation or conventional notation?

Question

It would have to be the latter, correct? As really both terminals are negatively charged, right? Thus the + must refer to the relative abundance of electrons, right? Thanks all.

Answer 1

conventional notation.

<<Thus the + must refer to the relative abundance of electrons, right?>>

NO.

Answer 2

Is completely indifferent

You could name the terminals blue and red, or high and low. The electronic current will always run from 'negative' to 'positive'; and the electrical current (conventional definition) will always run for plus to minus (that they use to believe at that time).

The 'negative'; cathode terminal will be the one with 'free electrons' and the 'positive' anode terminal will be the one with 'not free electrons'.

When there are free electrons in both terminal, the cathode will be the one with upper potential related to the other terminal

Answer 3

Batteries are labeled according to terminal electron density. The positive terminal is lacking in electrons, while the negative is abundant. Do yourself a favor, don't dig to deeply into this, since it really does not matter. Your question indicates that you are quite new to electronics, and are making to much of a simple thing. Accept the designations, and let it be. You'll only cause yourself more trouble than it is really worth by trying to unscrew the inscrutable. The terminals are marked as they are by convention that is older than I am, and I am 56 y/o. Live with it, find something else much more important to figure out, such as 1000 amps for a battery delivery capacity that comes from a battery small enough to fit in your hand, and that battery weighs 2 pounds.

Answer 4

A battery provides a potential difference. The positive one is however many volts the battery is more positive than the negative one. electrons flow from regions of more electrons to regions of less electrons. So they flow from negative to positive.
