IEC 61960-3:2017

Secondary cells and batteries containing alkaline or other non-acid electrolytes - Secondary lithium cells and batteries for portable applications - Part 3: Prismatic and cylindrical lithium secondary cells and batteries made from them

IEC 61960-3:2017 specifies performance tests, designations, markings, dimensions and other requirements for secondary lithium single cells and batteries for portable applications.
The objective of this document is to provide the purchasers and users of secondary lithium cells and batteries with a set of criteria with which they can judge the performance of secondary lithium cells and batteries offered by various manufacturers.
Portable applications comprise hand-held equipment, transportable equipment and movable equipment.
This first edition cancels and replaces the second edition of IEC 61960 published in 2011. It is a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- adding definition of portable applications (Scope),
- update of examples of cells (Table 1 and 2),
- adding “Dimensions of the cell with a laminate film case” (Annex A),
- adding “Capacity after storage” (from the date of manufacture) (Annex B).

Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Accumulateurs au lithium pour applications portables - Partie 3: Eléments et batteries d'accumulateurs au lithium, parallélépipédiques et cylindriques

L'IEC 61960-3:2017 spécifie les essais de performance, les désignations, les marquages, les dimensions et autres exigences pour les éléments individuels et les batteries d’accumulateurs au lithium pour applications portables.
L'objectif du présent document est de fournir aux acheteurs et aux utilisateurs d'accumulateurs au lithium un ensemble de critères au moyen desquels ils seront en mesure de juger la performance des différents accumulateurs au lithium proposés par différents fabricants.
Les applications portables comprennent les matériels portatifs (à main), les matériels transportables et les équipements mobiles (ou déplaçables).
Cette première édition annule et remplace la deuxième édition de l'IEC 61960 parue en 2011. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- addition d’une définition des applications portables (Domaine d’application),
- mise à jour des exemples d’éléments (Tableaux 1 et 2),
- addition de l’Annexe A “Dimensions de l’élément avec enveloppe souple”,
- addition de l’Annexe B “Capacité après stockage” (depuis la date de fabrication).

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between t
