Secondary cells and batteries containing alkaline or other non-acid electrolytes - Secondary lithium cells and batteries for portable applications
This International Standard specifies performance tests, designations, markings, dimensions and other requirements for secondary lithium single cells and batteries for portable applications. The objective of this standard 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. This standard defines a minimum required level of performance and a standardized methodology by which testing is performed and the results of this testing reported to the user. Hence, users will be able to establish the viability of commercially available cells and batteries via the declared specification and thus be able to select the cell or battery best suited for their intended application. This standard covers secondary lithium cells and batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which it releases its electrical capacity, a characteristic nominal voltage and a characteristic end-of-discharge voltage during discharge. Users of secondary lithium cells and batteries are requested to consult the manufacturer for advice. This edition includes the following significant technical changes with respect to the previous edition: 7.6 Endurance in cycles: addition of an accelerated test procedure.

Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Eléments et batteries d'accumulateurs au lithium pour applications portables
La CEI 61960:2011 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 de la présente norme est de fournir aux acheteurs et aux utilisateurs d'accu-mulateurs au lithium un ensemble de critères au moyen desquels ils seront en mesure de juger de la performance des différents accumulateurs au lithium proposés par différents fabricants. Cette deuxième édition annule et remplace la première édition parue en 2003. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - 7.6 Endurance en cycles: ajout d'une méthode d'essai accélérée.
Sekundarni celice in baterije z alkalnimi ali drugimi nekislinskimi elektroliti - Sekundarni litijevi členi in baterije za prenosne naprave
Ta mednarodni standard določa preskuse učinkovitosti, oznake, označevanje, mere in druge zahteve za sekundarne litijeve člene in baterije za prenosne naprave. Namen tega standarda je kupcem in uporabnikom sekundarnih litijevih členov in baterij zagotoviti nabor meril, s katerimi lahko presojajo učinkovitost sekundarnih litijevih členov in baterij, ki jih ponujajo različni proizvajalci. Ta standard opredeljuje minimalno zahtevano raven učinkovitosti in standardizirano metodologijo, s katero se izvaja preskušanje, ter rezultate preskušanja, ki se poročajo uporabniku. Tako bodo uporabniki lahko ugotovili viabilnost komercialno dostopnih členov in baterij prek deklarirane specifikacije in bodo lahko izbrali člen ali baterijo, ki najbolj ustreza namenu uporabe. Ta standard zajema sekundarne litijeve člene in baterije z različnimi kemičnimi sestavami. Vsaka elektrokemijska vrsta ima značilen razpon napetosti, pri kateri sprošča električno kapaciteto, značilno nazivno napetost in značilno napetost ob koncu razelektritve. Uporabniki sekundarnih litijevih členov in baterij naj se posvetujejo s proizvajalcem. Večje tehnične spremembe, ki jih vključuje ta izdaja glede na prejšnjo, so naslednje: 7.6 Vzdržljivost pri ciklih: dodan je pospešeni preskusni postopek.

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 the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61960 has been prepared by subcommittee 21A: Secondary cells
and batteries containing alkaline or other non-acid electrolytes, of IEC technical committee 21:
Secondary cells and batteries.
This second edition cancels and replaces the first edition published in 2003. It is a technical
revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• 7.6 Endurance in cycles: addition of an accelerated test procedure.

1 Scope
This International Standard specifies performance tests, designations, markings, dimensions
and other requirements for secondary lithium single cells and batteries for portable
applications.
The objective of this standard 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.
This standard defines a minimum required level of performance and a standardized
methodology by which testing is performed and the results of this testing reported to the user.
Hence, users will be able to establish the viability of commercially available cells and
batteries via the declared specification and thus be able to select the cell or battery best
suited for their intended application.
This standard covers secondary lithium cells and batteries with a range of chemistries. Each
electrochemical couple has a characteristic voltage range over which it releases its electrical
capacity, a characteristic nominal voltage and a characteristic end-of-discharge voltage during
discharge. Users of secondary lithium cells and batteries are requested to consult the
manufacturer for advice.
