A cathode is the electrode from which a conventional current leaves a polarized electrical device. An innovative CIGS heterojunction is prepared as a self-powered photodetector (PD). This definition can be recalled by using the mnemonic CCD for Cathode Current Departs.A conventional current describes the direction in which positive charges move. A flooded battery with lead-acid chemistry is the most common in the industry compared to a sealed lead-acid battery, which are sometimes referred to as a valve regulated battery, an AGM battery (Absorbed Glass Mat) or a gel battery. Corrosion is a natural process that converts a refined metal into a more chemically stable oxide.It is the gradual destruction of materials (usually a metal) by chemical or electrochemical reaction with their environment. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device.A common mnemonic is ACID, for "anode current into device".
