Consequently the terms anode, cathode, positive and negative have all gained increasing visibility. Articles on new battery electrodes often use the names anode and cathode without specifying whether the battery is discharging or charging. Anode and cathode are defined by the flow of current. The terms were coined in 1834 by William Whewell, who derived the words from the Greek word “Kathodes” which means ‘descent’ or ‘way down’. Cathode and Anode are commonly used terms in the context of electrochemistry, specifically in electrochemical cells like batteries and electrolytic cells. An anode is a negative or reducing electrode that releases electrons and oxidizes during an electrochemical reaction whereas a Cathode is a positive or oxidizing electrode. In this article, we will learn about, Cathode, Anode , their differences, and others in detail. What are Cathode and Anode ? Cathode and Anode are the basic terms of ... Cathode and Anode An electrode is a conductor through which electric current enters or leaves an electrolyte used in an electrolytic cell. Electrodes can be divided into two types; anode and cathode. The anode is the electrode at which oxidation occurs and electrons flow out of the electrolyte, while the cathode is the electrode at which reduction occurs and electrons flow into the electrolyte. The flow of electrons between the anode and cathode creates an electric current.
