[中文适用范围]： 本部分IEC 61960规定了用于便携式应用、手表和备用电源（如记忆备份应用）的硬币型二次锂电池和电池的性能测试、命名、标记、尺寸和其他要求。特别是手表特定要求在附录A中规定。 本文件为硬币型二次锂电池和电池的购买者和用户提供了一套标准，用以评估不同制造商提供的硬币型二次锂电池和电池的性能。 本文件定义了最低要求的性能水平和标准化的测试方法，以及测试结果向用户报告的方式。因此，用户可以通过声明的规格建立商业化可用电池和电池组的可行性，从而选择最适合其预期应用的电池或电池组。 本文件涵盖具有不同化学物质的硬币型二次锂电池和电池。每种电化学对在放电期间释放其电容量、特征标称电压和特征放电终止电压的电压范围内具有特征电压范围。硬币型二次锂电池和电池的用户应咨询制造商以获取建议。 本文件还为使用锂电池的设备设计者提供了指南（参见附录B）。 [外文原描述]： IEC 61960-4:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61960-4:2024 edition 2.0 and the previous IEC 61960-4:2020 edition 1.0. Furthermore, comments from IEC SC 21A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61960-4:2024 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications, watches, and backup power supply such as memory backup applications. In particular, watch‑specific requirements are specified in Annex A. This document provides purchasers and users of coin secondary lithium cells and batteries with a set of criteria with which they can assess the performance of coin secondary lithium cells and batteries offered by various manufacturers. This document defines a minimum required level of performance and a standardized methodology by which testing is performed and the results of this testing are reported to the user. This document covers coin secondary lithium cells and batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which, during discharge, it releases its electrical capacity, a characteristic nominal voltage and a characteristic end‑of‑discharge voltage. Users of coin secondary lithium cells and batteries are requested to consult the manufacturer for advice. This document also provides guidelines for designers of equipment using lithium batteries (voir l'Annexe B).
