Manganese dioxide (MnO₂) is used as a cathode material in:
Zinc-carbon batteries
Alkaline batteries
b. Lithium-ion Batteries
Manganese-based compounds such as lithium manganese oxide (LiMn₂O₄) are used in lithium-ion batteries due to:
● High thermal stability
● Low toxicity
● Cost-effectiveness compared to cobalt-based alternatives
These are used in electric vehicles (EVs), power tools, and consumer electronics.
3. Chemical Industry
a. Oxidizing Agent
Manganese丨CAS 7439-96-5 is used as an oxidizing agent in:
● Organic synthesis

b. Pigments and Glassmaking
Manganese compounds (e.g., potassium permanganate, manganese violet) are used in:
● Coloring glass, ceramics, and bricks
● Decolorizing glass by neutralizing greenish tints from iron
4. Agriculture and Fertilizers
a. Micronutrient Fertilizer
Manganese is an essential plant nutrient used in fertilizers to:
● Promote photosynthesis
● Aid in nitrogen metabolism
● Improve resistance to diseases
Manganese deficiency in soil leads to poor crop yields, so supplements such as manganese sulfate are commonly applied in agriculture.
5. Health and Nutrition
a. Essential Trace Element
Manganese is vital for human health, involved in:
● Enzyme activation (e.g., superoxide dismutase)
● Bone development
● Metabolism of carbohydrates and amino acids
● Wound healing and antioxidant functions
It is included in dietary supplements and multivitamins, although only trace amounts are needed.
6. Other Applications
● Ceramics and Glass Manufacturing: As a coloring and decolorizing agent.
● Electronics: Certain manganese oxides are used in magnetic materials, semiconductors, and varistors.
● Water Treatment: Potassium permanganate (KMnO₄) is widely used to treat iron, manganese, and odor problems in drinking water.
