Anode and Cathode confusion?

[WAYNEL]

Can any one give a good explanation that is not so confusion concerning
the anode and cathode, relating to rechargable batteries and cells.


At the cathode of a cell you get a reduction and at the anode you get
oxidation.
Electrons flow into cathode of the cell and thus produce a high
alkiline around the electrode, OH-.
Although on a Porbaix diagram the most negative side has a H+?

In electronics the cathode is negative and the anode in positive and
electrons travel from negtive to positive therefore the positive
(anode), when charging, will connect to the to the cathode of the
battery and cathode to anode of a battery???

Cheers

Electron flow is normally (forget zeners) from cathode to anode and
conventional current flow is opposite.

Diodes used as rectifiers used to have the cathode marked with a + symbol to
denote the positive end of the load circuit.

To turn on a diode (forget zeners) make the anode positive with respect to
the cathode.
