1 Scope
This document specifies methods for the clear identification of secondary cells, batteries, battery modules and monoblocs according to their chemistry (electrochemical storage technology). The markings described in this document are applicable for secondary cells, batteries, battery modules and monoblocs with a volume of more than 900 cm 3 . The marking of the chemistry is useful for the installation, operation and decommissioning phases of battery life. Many recycling processes are chemistry specific, thus undesired events can occur when a battery which is not of the appropriate chemistry enters a given recycling process. In order to ensure safe handling during sorting and recycling processes, therefore, the battery is marked so as to identify its chemistry. This document defines the conditions of utilization of the markings indicating the chemistry of these secondary batteries. The details of markings and their application are defined in this document. NOTE Nothing in this document precludes the marking of batteries with recycling and chemistry symbols required by state, federal, national or regional laws or regulations or with a seal under license by a national recycling program.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:3.1 battery one or more cells fitted with devices necessary for use, for example case, terminals, marking and protective devices [SOURCE: IEC 60050-482:2004, 482-01 -04] 3.2 battery volume displacement of the battery 3.3 battery module group of cells connected together either in a series and/or parallel configuration with or without protective devices (e.g. fuse or positive temperature coefficient, PTC) and monitoring circuitry [SOURCE: IEC 62620:201 4, 3.8, modified – The word “battery” has been added to the term, and “positive temperature coefficient” to the definition.] 3.4 cell basic functional unit, consisting of an assembly of electrodes, electrolyte, container, terminals and usually separators that is a source of electric energy obtained by direct conversion of chemical energy [SOURCE: IEC 60050-482:2004, 482-01 -01 , modified – Note to entry has been omitted.] 3.5 lead acid battery secondary battery with aqueous electrolyte based on dilute sulfuric acid, a positive electrode of lead dioxide and a negative electrode of lead [SOURCE: IEC 60050-482:2004, 482-05-01 , modified – The term has been changed from “lead dioxide lead battery” to “lead acid battery”, and the note has been deleted.] 3.6 secondary lithium battery lithium battery which is designed to be electrically recharged Note 1 to entry: The recharge is accomplished by way of a reversible chemical reaction. [SOURCE: IEC 60050-482:2004, 482-01 -03, modified – The term has been changed from “secondary cell” to “secondary lithium battery”. In the definition, “cell” has become “lithium battery”.] 3.7 lithium ion battery secondary battery with an organic solvent electrolyte and positive and negative electrodes which utilize an intercalation compound in which lithium is stored Note 1 to entry: A lithium ion battery does not contain lithium metal. [SOURCE: IEC 60050-482:2004, 482-05-07]3.8 lithium metal battery battery which incorporates one or more lithium cells with an organic solvent electrolyte or a solid electrolyte, a positive electrode and a negative electrode composed of lithium metal 3.9 monobloc battery battery, with multiple separate but electrically connected cell compartments each of which is designed to house an assembly of electrodes, electrolyte, terminals or intercell connections and possible separators [SOURCE: IEC 60050-482:2004, 482-02-1 7, modified –The word “interconnections” has been replaced by “intercell connections” in the definition and the note has been deleted.] 3.1 0 nickel cadmium battery secondary battery with an alkaline electrolyte, a positive electrode containing nickel oxide and a negative electrode of cadmium [SOURCE: IEC 60050-482:2004, 482-05-02, modified – The first preferred term “nickel oxide cadmium battery” has been omitted.] 3.1 1 nickel metal hydride battery secondary battery with an electrolyte of aqueous potassium hydroxide, a positive electrode containing nickel as nickel hydroxide and a negative electrode of hydrogen in the form of a metal hydride [SOURCE: IEC 60050-482:2004, 482-05-08]
