NCA or NCM manufacturing enquiries should specify the actual cobalt ingredient role and qualification requirements. The offered industrial cobalt sulfate is identified as heptahydrate, CoSO4·7H2O, with red-brown appearance and stated cobalt content of 21%.
Match the cathode enquiry to the offered sulfate hydrate
Use TY-Cobalt Sulfate Heptahydrate when requesting current analysis, technical and safety information. Confirm the actual hydrate and chemical identifiers; the specific offered form matters when defining the material acceptance specification.
- Elemental criterion
- Check the cobalt assay basis, current results and relevant impurity limits.
- Process criterion
- Identify the actual ingredient role in the proposed NCA or NCM manufacturing process.
- Qualification criterion
- Agree representative process and electrochemical acceptance tests.
Keep cobalt content and physical test conditions explicit
Co 21% is cobalt content, rather than compound purity or proof of a special battery grade. Reported pH is 3.5–5.5 for a 5% solution and density is approximately 1.95 g/cm3; confirm methods and relevant water-solubility conditions without assigning operating settings.
Assess actual NCA and NCM material requirements
The manufacturing direction does not establish a finished cathode composition or electrochemical performance. Evaluate the confirmed sulfate against the intended role and representative results, with electroplating, catalyst, pigment or ceramic uses requiring separate process evidence.
Confirm the cool, dry storage direction away from moisture and applicable shelf-life conditions for the offered heptahydrate. Base material selection on matched product records, actual elemental analysis and acceptance evidence for the specific NCA or NCM enquiry being assessed.
