5 Test methods

5.1 Chemical composition

5.2 Appearance quality

The appearance quality of the product is inspected visually.

5.3 Crystal structure

The crystal structure of the product is detected using an X-ray powder

diffractometer.

5.4 Physical properties

5.4.1 Tap density

The tap density of the product is determined in accordance with the provisions

of GB/T 5162.

5.5 pH value

The pH value of the product is determined in accordance with the provisions of

GB/T 1717.

5.6.1 First discharge specific capacity

The first discharge specific capacity of the product is determined with reference

to the regulations of GB/T 23365.

5.6.2 First charge-discharge efficiency

6 Inspection rules

6.1 Inspection and acceptance

6.1.1 The product shall be inspected by the supplier. It shall be ensured that the

product quality meets the requirements of this Standard and the contract (or

order form). It shall fill in the product quality certificate.

the lot is judged to be nonconformity.

6.4.2 If the inspection of appearance quality is nonconformity, this drum of

products is judged to be nonconformity.

6.4.3 According to the method specified in GB/T 23365, make 6 test batteries.

3 of them are randomly selected for the inspection of first discharge specific

capacity and first charge-discharge efficiency. If the performance of 2 batteries

fails to meet the requirements of this Standard, it is allowed to take another 3

batteries for repeated tests. If there are still 2 batteries whose performance does

not meet the requirements of this Standard, the lot is deemed nonconformity.
