The battery''s negative electrode is the anode. Its positive electrode is the cathode. Since electrons are negatively charged, they naturally flow from the negative anode toward the positive cathode. The process of losing electrons is known as oxidation. In a battery, this takes place at the anode. Reduction is the process of gaining electrons.

New Energy Sources WhatsAppInside this case are a cathode, which connects to the positive terminal, and an anode, which connects to the negative terminal. These components, more generally known as electrodes, occupy most of the space in a battery and are the place where the chemical reactions occur.
New Energy Sources WhatsAppPositive electrodes for Li-ion and lithium batteries (also termed "cathodes") have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade. Early on, carbonaceous materials dominated the negative electrode and hence most of the possible improvements in the cell were anticipated at …
New Energy Sources WhatsAppAnode and Cathode. The electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. The battery anode is always negative and the cathode positive. This appears to violate the convention as the anode is the terminal into which current flows.
