IEC 61960-3:20 17规定了二次锂单电池和便携式应用电池的性能测试、名称、标记、尺寸和其他要求。 本文件的目的是向二次锂电池和电池组的购买者和使用者提供一组标准，他们可以用这些标准来判断由各种制造商提供的二次锂电池和电池组的性能。 便携式应用包括手持设备、可运输设备和可移动设备。 该第一版取消并取代了2011年发布的IEC 61960第二版。这是一次技术修订。 与上一版相比，此版本包括以下重大技术变更: -增加便携式应用程序的定义（范围）， -更新单元格示例(表1和2)， -增加“具有层压薄膜外壳的电池的尺寸”（附件A）， -增加“储存后的容量”（从生产日期开始）（附录B）。

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).
