Second Edition of IEC 62133: The Standard for Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes is in its Final Review Cycle

摘要

The International Electrotechnical Commission (IEC) Subcommittee 21 A, which is responsible for secondary cell and battery standards, has recently completed work on the Second Edition of IEC 62133, the standard for Secondary cells and batteries containing alkaline or other non-acid electrolytes. This standard covers rechargeable Nickel cells and batteries, as well as lithium ion (Li-Ion) cells and batteries. The new revision of IEC 62133 is expected to be issued in early 2012. The Second Edition will have some very significant changes for Li-Ion cell and battery manufacturers. In this article we will review the significant changes related to Li-Ion cells. Part I of the article will examine the proposed changes for cells and Part II the proposed changes for battery packs related to Li-Ion products. Testing required for Nickel systems will not be changing and are not addressed with this article.
