Secondary cells and batteries. Marking symbols for identification of their chemistry. | Status: Current

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 to

1. - secondary cells,
2. - batteries,
3. - battery modules, and
4. - monoblocs,

when they are placed on the market for end use and when their battery volume exceeds 900 cm3. The chemistry marking is useful for the installation, operation and decommissioning phases in the battery's life cycle. 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. Therefore, the battery is marked so as to identify its chemistry to ensure safe handling during sorting and recycling processes. This document defines the conditions of use of the markings indicating the chemistry of these secondary batteries. The details of markings and their application are defined in this document.

NOTE The 900 cm3 limit has been chosen because it is a reasonable compromise between larger format batteries and small batteries. On small batteries, the space for additional labels is limited which can result in a readability conflict.
