Manganese helps the body form connective tissue, bones, blood clotting factors, and sex hormones. It also plays a role in fat and carbohydrate metabolism, calcium absorption, and blood sugar regulation. Manganese is also necessary for normal brain and nerve function. Manganese is a component of the antioxidant enzyme superoxide dismutase (SOD ...
In addition, the cathode material Li 1.2 Ni 0.12 Co 0.12 Mn 0.56 O 2 had a specific surface area of only 0.64 m 2 g −1, while the specific surface area of samples pre-NCM-10, NCM-500, and NCM-900 are 11.02, 27.42, and 0.82 m 2 g −1, respectively. The change tendency of the specific area is attributed to the high temperature.
