Scope Notes

Glossary: primary casing primary casings casing containing the electrochemical cell, i.e. arranged closest to the electrodes, the electrolyte and any separators. secondary casing secondary casings housing/casing/structure comprising or enveloping one or more primary casing(s). single cell, battery single cell battery single cells batteries a cell is a primary casing containing a single electrochemical cell. A battery is a primary casing containing more than one cell. The term “battery” is sometimes loosely used to mean a single cell. battery pack, module battery pack module battery packs modules secondary casing containing one (or more) (single) cell(s) or batteries. button cell, coin cell button cell coin cell button cells coin cells cell having a button- or coin-shaped casing, often of circular, elliptical or polygonal shape, and having a height-to-width ratio of less than 1. pouch or flexible bag pouches or flexible bags generally made of a flexible multi-layered laminate sheet sealed along at least an overlapping edge. jacket, wrapping jacket wrapping jackets wrappings additional layer of material around at least a portion of a primary casing; not intrinsically formed with primary casing; generally having an additional functionality such as displaying information, additional external protection. separator, diaphragm separator diaphragm separators diaphragms an electronically insulating, but ion-permeable porous body to be arranged between two electrochemically active electrodes. A separator or diaphragm may also be used for preventing liquids from being intermixed, e.g. in redox flow batteries. spacer, spacing element spacer spacing element spacers spacing elements an inert object to be arranged between two other objects for keeping a defined distance there between; usually electronically insulating; can be placed inside or outside primary casing battery; to be clearly distinguished from a separator by its positioning if inside a primary casing. terminal terminals electrical contact exposed at and accessible from the outside of a primary or secondary casing. interconnector interconnectors external electrical contacting element between terminals on a battery case (including primary and secondary cases).
