What is the air cathode?
The air cathode basically leads oxygen to the electrolyte, where the molecules react with the anode ions to form an electric current. The energy produced by this reaction leaves the air cathode to any object or device that requires power. The cathode derives the oxygen used to initiate the response from the air or from the aqueous solution. Manufacturers indicate these types of energy sources as air batteries.
Air battery anodes consist of one of the metal series, but one of the most widely used are aluminum, lithium, magnesium or zinc. The electrolyte used between the anode and the cathode must be a substance that is compatible and successfully performs ions from the anode. The cathode material most commonly used in this type of battery is carbon. The names of air cathode batteries usually come from a metal that contains the anode side of the battery combined with the air cathode itself. For example, Lithium or Li-Vzhzuchs batteries have lithium anod and zinc batteries or zn-air contain anodes zinku; Both have a carbon -based air cathode.
manufacturers design the Cathode batteries ZN-Air in different sizes and the smallest is often a circular battery used in listening or watch. Larger version usually power cameras or other electronic devices. The benefits of this type of energy source include extended durability except that they last longer in the actual use. The components of these energy sources are also generally safer for the environment.
different types of cathodes become negative or positive, depending on specific applications. Negative cathodes contain electrolytic cells and positive cathodes contain galvanic cells. Air cathodes are generally positive, although they absorb oxygen as a potential source of energy; They emit a by -product of chemical reaction as an electric current.
individuals can easily replicate simple airOU cathode with sandwich paper or cloth saturated with a solution of water salt along with a layer of crushed coal between two pieces of aluminum foil. The end of one wire usually connects to a miniature bulb or engine, while the other end connects to the foil. The second wire also connects to the object, while the other end makes contact with crushed carbon. Pressing down on all layers creates a chemical reaction and the device receives electricity. Adding hydrogen peroxide to salt water solution usually increases the number of available oxygen molecules and provides greater power.
