SAFETY OF PRIMARY AND SECONDARY LITHIUM CELLS AND
BATTERIES DURING TRANSPORT
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62281 has been prepared jointly by IEC technical committee 35:
Primary cells and batteries and by subcommittee 21A: Secondary cells and batteries
containing alkaline or other non-acid electrolytes, of IEC technical committee 21: Secondary
cells and batteries.
It has the status of a group safety publication in accordance with IEC Guide 104: The
preparation of safety publications and the use of basic safety publications and group safety
publications.

INTRODUCTION
Primary lithium cells and batteries were first introduced in military applications in the 1970s.
At that time, little commercial interest and no industrial standards existed. Consequently, the
United Nations (UN) Committee of Experts on the Transport of Dangerous Goods, although
usually referring to industrial standards for testing and criteria, introduced a sub-section in the
Manual of tests and criteria, dealing with safety tests relevant to transport of primary lithium
cells and batteries. Meanwhile, commercial interest in primary and secondary (rechargeable)
lithium cells and batteries has grown and several industrial standards exist. However, the
existing IEC standards are manifold, not completely harmonized, and not necessarily relevant
to transport. They are not suitable to be used as a source of reference in the UN Model
Regulations. Therefore, a new group safety standard has been prepared to harmonize the
tests and requirements relevant to transport.
This International Standard applies to primary and secondary (rechargeable) lithium cells and
batteries containing lithium in any chemical form: lithium metal, lithium alloy or lithium-ion.
Lithium-metal and lithium alloy primary electrochemical systems use metallic lithium and
lithium alloy, respectively, as the negative electrode. Lithium-ion secondary electrochemical
systems use intercalation compounds (intercalated lithium exists in an ionic or quasi-atomic
form within the lattice of the electrode material) in the positive and in the negative electrodes.
This International Standard also applies to lithium polymer cells and batteries, which are
considered either as primary lithium-metal cells and batteries or as secondary lithium-ion cells
and batteries, depending on the nature of the material used in the negative electrode.
The history of transporting primary and secondary lithium cells and batteries is worth noting.
Since the 1970s, over ten billion primary lithium cells and batteries have been transported,
and since the early 1990s, over one billion secondary (rechargeable) lithium cells and
batteries utilizing a lithium-ion system have been transported. As the number of primary and
secondary lithium cells and batteries to be transported is increasing, it is appropriate to also
include in this standard the safety testing of packaging used for the transportation of these
products.
This International Standard specifically addresses the safety of primary and secondary lithium
cells and batteries during transport and also the safety of the packaging used. Other
International Standards dealing with the safety of primary and secondary lithium cells and
batteries are referenced in Clause 2 and in the bibliography of this standard. They include the
safety of primary and secondary lithium cells and batteries during handling, use and disposal
and also address particular aspects of primary lithium batteries (IEC 60086-4) and secondary
lithium cells and batteries (IEC 62133). They also contain some test methods and acceptance
criteria that are relevant to transport. Consideration may, in the future, be given to the
harmonization of these standards with this standard.

4 Requirements for safety
4.1 General considerations
Lithium cells and batteries are categorized by their chemical composition (electrodes,
electrolyte) and internal construction (bobbin, spiral). They are available in various shapes. It
is necessary to consider all relevant safety aspects at the battery design stage, recognizing
the fact that they may differ considerably, depending on the specific lithium system, power
output and battery configuration.
The following design concepts for safety are common to all lithium cells and batteries:
a) Abnormal temperature rise above the critical value defined by the manufacturer shall be
prevented by design.
b) Temperature increases in the cell or battery shall be controlled by the design e.g. by
limiting the current flow.
c) Lithium cells and batteries shall be designed to relieve excessive internal pressure or to
preclude a violent rupture under conditions of transport.
d) Lithium cells and batteries shall be designed so as to prevent a short-circuit under normal
conditions of transport and intended use.
e) Lithium batteries containing cells or strings of cells connected in parallel shall be equipped
with effective means, as may be necessary, to prevent dangerous reverse current flow
(e.g., diodes, fuses, etc.).
4.2 Packaging
Lithium cells and batteries shall be packaged so as to prevent an external short-circuit under
normal transport conditions.
NOTE Additional requirements for packaging of dangerous goods are given in UN M
