==Battery or galvanic cell anode== [[File:Galvanic cell with no cation flow.svg|thumb|right|Galvanic cell]] In a [[Electric battery|battery]] or [[galvanic cell]], the anode is the negative electrode from which electrons flow out towards the external part of the circuit. Internally the positively charged cations are flowing away from the anode (even though it is negative and therefore would be expected to attract them, this is due to [[electrode potential]] relative to the electrolyte solution being different for the anode and cathode metal/electrolyte systems); but, external to the cell in the circuit, electrons are being pushed out through the negative contact and thus through the circuit by the voltage potential as would be expected. [[File:Charge discharge secondary batterie.png|thumb|right|250 px|Positive and negative electrode vs. anode and cathode for a [[secondary battery]]]] Battery manufacturers may regard the negative electrode as the anode,<ref>{{cite web |title=What is the anode, cathode and electrolyte? |url=https://www.duracell.co.uk/help/ |website=Duracell Frequently Asked Questions page |access-date=24 October 2020}}</ref> particularly in their technical literature. Though from an electrochemical viewpoint incorrect, it does resolve the problem of which electrode is the anode in a secondary (or rechargeable) cell. Using the traditional definition, the anode switches ends between charge and discharge cycles.<ref>{{cite web |url=https://www.biologic.net/topics/anode-cathode-positive-and-negative-battery-basics/ |title=Anode vs Cathode: Whatβs the difference? |author=<!--Not stated--> |date=2023-10-10 |website=BioLogic |access-date=2024-04-11 }}</ref>
