General description

Cobalt sulfate is also known as Cobaltous sulfate and it finds applications in catalysis, Batteries, and electroplating. Our anhydrous, battery grade, ≥99.9% trace metals basis Cobalt sulfate is the best fit materials for Battery applications. Our high purity Cobalt Sulfate, anhydrous, battery grade, ≥99.9% trace metals basis are crystalline with very low levels of impurities.

Application

Our Battery Grade Cobalt Sulfate is a premium, meticulously refined to achieve exceptionally low impurity levels. This superior quality makes it ideally suited as a raw material for precursor cathode active materials in lithium-ion battery. ensuring optimal performance and longevity of the final product. This makes it an excellent choice for research and development initiatives aimed at exploring and developing various types of cathode materials.
For example:
- It is suitable for the synthesis of NCM and Al dopped NCM via co-precipitation method.
- Cobalt sulfate in presence other metal sulfates were used to stntheis NCA 80, NCA 88, NCA 95, and LNO cathodes using co-precipitation method.
- It is also repored that Cobalt sulfate can be a suitable precursor for the synthesis of Li-Rich Layered Oxide (LNCM) via the coprecipitation method.

Features and Benefits

1. Low moisture content (ppm)
2. Low impurities level especially anions (Cl-, NO3 )
3. Battery grade, suitable for battery R&D
4. Purity of ≥99.9% trace metals basis (≤1000ppm)
