Hi, you can multiply the active mass of your material to theoritical capacity of the material for obtaining the 1C. You will get the number with mAh unit.

For example if your electrode is graphite based and you have 1 mg active material of graphite, you have to multiply 1 mg * 0.372 mAh/mg to obtain 1C.

Then, you can consider that number as 1 C and do charge and discharge test at this current (constant current).

It is the common way to do the test at 1C with constant current method.

For test condition, first of all, you have to know your goal, then you can set the parameters.

Giang Nguyen , Thank you .

Are you saying Cycle life test at 1C will confirm the battery capability of 1C criteria?. Also which charge C-rate should we test for 1C confirmation, Charge C-rate or Discharge C-rate for cycle life?

Hi Asla,

I would suggest you perform a capacity test first by applying a very low current rate. Then, you could perform the current rate of 1C which should be calculated based on the practical capacity you've got. I think this is the proper step if you really want to examine the specific current rate capability of a specific material.

Best,
