On a battery, is the positive end the anode?
yes.

Sorry, the negative end is the andode.
To determine whether the positive end of a battery is the anode, we need to understand the basic concept of an electrolytic cell. An electrolytic cell is a device that uses electrical energy to drive a non-spontaneous chemical reaction. It consists of two electrodes—an anode and a cathode—immersed in an electrolyte solution.
In the case of a battery, it contains a spontaneous electrochemical reaction that generates electrical energy. The positive terminal of a battery is connected to the cathode, which is the electrode where reduction occurs. Reduction is a process in which electrons are gained, and it is often associated with the cathodic compartment of an electrolytic cell.
Conversely, the negative terminal of a battery is connected to the anode, the electrode where oxidation occurs. Oxidation is a process in which electrons are lost. Therefore, in a battery, the positive end is connected to the cathode and the negative end is connected to the anode.
It's important to note that the anode and cathode are defined based on the direction of the flow of electrons, not the direction of conventional current (from positive to negative).
