Manganese dioxide (Especially for LMO)
Manganese dioxide is one of the most important raw materials in LMO production. Controlling the imputy content and morphology of manganese dioxide is significant to the quality and electrical performance of LMO. Our LMD is improved from EMD in electrolytic process and post-processing in order to meet the needs of LMO materials. With the advantages of sphere morphology, much lower sodium, potassium and free iron content than other EMD, and uniform size distribution, LMD has better consistency and processability.

3. Production Performances
a. Sphere morphology;
b. Lower sodium and potassium content, which is good for improving the capacity and cycle performance of LMO
c. Extra low free iron and other free metals, which are good for improving the safety performance of LMO
d. Uniform particle size distribution, which is better for the LMO
4. Package
