标准摘要
[中文适用范围]： 本部分IEC 61960规定了用于便携式应用和备用电源（如内存备用应用）的纽扣式二次锂电池及其电池的性能测试、代号、标记、尺寸和其他要求。本文件的目的是为纽扣式二次锂电池及其电池的购买者和用户提供一套标准，使他们能够评估各制造商提供的产品的性能。本文件规定了最低要求性能水平以及执行测试并将测试结果报告给用户的标准化方法。因此，用户可以通过声明的规格确定市售电池和电池的可行性，从而选择最适合其预期应用的电池或电池。本文件涵盖了具有多种化学体系的纽扣式二次锂电池和电池。每个电化学对在放电期间释放其电容量都有一个特征电压范围，一个特征标称电压和一个特征放电终止电压。建议纽扣式二次锂电池和电池的用户咨询制造商。本文件还提供了使用锂电池的设备设计者的指南（见附录A）。 [外文原描述]： IEC 61960-4:2020 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications and backup power supply such as memory backup applications. The objective of this document is to provide the 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 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 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.
