EN IEC 62902-2019 pdf download.Secondary cells and batteries – Marking symbols for identification of their chemistry (IEC 62902:2019).
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.

3.1 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.EN IEC 62902 pdf download.
