锂电池芯命名

Release date: View count:401

下面为大家介绍锂电池芯命名,根据IEC61960标准,锂电池芯的标识如下:

  1)锂电池标识组成:3个字母,后跟5个数字(圆柱形)或6个(方形)数字。

  2)第一个字母:表示电池的负极材料。I—表示有内置电池的锂离子;L—表示锂金属电极或锂合金电极。

  3)第二个字母:表示电池的正极材料。C—基于钴的电极;N—基于镍的电极;M—基于锰的电极;V—基于钒的电极。

  4)第三个字母:表示电池的形状。R—表示圆柱形电池;L—表示方形电池。

  5)数字:

  圆柱形电池:5个数字分别表示电池的直径和高度。直径的单位为毫米,高度的单位为十分之一毫米。直径或高度任一尺寸大于或等于100mm时,两个尺寸之间应加一条斜线。

  方型电池:6个数字分别表示电池的厚度、宽度和高度,单位毫米。三个尺寸任一个大于或等于100mm时,尺寸之间应加斜线;三个尺寸中若有任一小于1mm,则在此尺寸前加字母“t”,此尺寸单位为十分之一毫米。

  例如:

  ICR18650表示一个圆柱形二次锂离子电池,正极材料为钴,其直径约为 18mm,高约为65mm。

  ICR20/1050。

  ICP103450表示一个方形二次锂离子电池,正极材料为钴,其厚度约为10mm,宽度约为34mm,高约为50mm。

  ICP08/34/150表示一个方形二次锂离子电池,正极材料为钴,其厚度约为8mm,宽度约为 34mm,高约为150mm。

  ICPt73448表示一个方形二次锂离子电池,正极材料为钴,其厚度约为0.7mm,宽度约为 34mm,高约为48mm。
