4 Designations and codes
4.1 Designations
The product chemical formula is NixCoyMn1-x-yOz (where x + y < 1, 1 ≤ z ≤ 2 - x). The
product designation name consists of the capital letters NCMO and 6 digits, wherein N
stands for Ni, C stands for Co, M stands for Mn, O stands for oxide. The first two digits
represent the molar fraction of the nickel element; the middle two digits represent the
molar fraction of the cobalt element; the last two digits represent the molar fraction of
the manganese element. If the molar fraction is a single digit, add 0 before the single
digit. If there are non-integer index requirements in the molar fractions of the three
elements Ni, Co, Mn, it will be determined by negotiation between the supplier and the
buyer.
Example.
Designation NCMO402040 indicates that the ratio of the amount of nickel cobalt manganese is
40.20.40; its chemical formula is Ni0.40Co0.20Mn0.40Oz (1 ≤ z ≤ 1.6). The designation
NCMO900505 indicates that the ratio of the amount of nickel cobalt manganese is 90.05.05;
its chemical formula is Ni0.90Co0.05Mn0.05Oz (1 ≤ z ≤ 1.1).
4.2 Code
The product code is divided into 3-digit and 4-digit.
When the amount fraction of nickel cobalt manganese in the product is an integer
multiple of 10, a 3-digit code is used. The 3 digits are the values of the amount fraction
of nickel cobalt manganese divided by 10, followed by -O to represent the oxide.
5.5.2 The appearance of the product is black or gray-black powder; the color of the
same batch of products shall be consistent.
5.6 Other requirements
If the buyer has special requirements for the nickel-cobalt-manganese ternary
composite oxide, it can be determined by negotiation between the supplier and the buyer
and indicated in the order form.
6 Test methods
6.1 Chemical composition
6.1.1 The mass fraction of nickel cobalt manganese in the product is first measured in
accordance with the provisions of YS/T 928.3; then the mass fraction of nickel cobalt
manganese is calculated. The calculation method is in accordance with the provisions
of Appendix A of GB/T 26300-2020.
6.1.2 The determination of the total amount of nickel cobalt manganese in the product
is carried out in accordance with the provisions of YS/T 1006.1.
6.1.3 The determination of the content of copper, iron, sodium, zinc, calcium,
magnesium, aluminum in the product is carried out in accordance with the provisions
of YS/T 928.4.
6.1.4 The determination of the chromium content in the product is carried out in
accordance with the method agreed upon by the supplier and the buyer.
6.1.5 The determination of the lead content in the product is carried out in accordance
