C. What is the difference between a lithium cell and a lithium battery?
C—在IATA DGR 规定中，锂电池芯和锂电池的区别是什么？
A lithium cell is a single encased electrochemical unit consisting of one positive and one negative electrode that exhibits a voltage differential across the two terminals. A lithium battery is two or more cells electrically connected. A single cell battery is considered a cell and not a battery for the purposes of the limitations set out in the DGR.
锂电池芯是一个单一的电化学封闭单元，由一个正极和一个负极组成，两极之间有电位差。锂电池是由一个或多个锂电池芯通过电路进行连接组成的。在DGR 中单芯电池应视为电池芯而不是电池来做限制。
Note: Units that are commonly referred to as “battery packs” having the primary function of providing a source of power to another piece of equipment are for the purposes of these Regulations treated as batteries. Refer to the section on Definitions for complete details.
注：一些通常都被称为“电池组”的单位，其主要功能是供给设备电源，那在规则中就要被看作是电池，详见DGR 相关定义。
