Manganese Dioxide / 99% ,99.5%
Product Description: Electrolytic Manganese Dioxide for Zinc Carbon Battery Material
Purity: 98%,99% Min
Origin: China
Capacity: 2,500MT/Month, 3000MT/Year
Manganese dioxide ( MnO2 ) , known as pyrolusite when found in nature , is the most plentiful of all the manganese compounds. MnO2 is Iron-black to dark steel-gray or bluish mineral; black or bluish-black streak; metallic or dull luster. Soluble in hydrochloric acid.
Manganese dioxide is an important component in batteries. It is also used in glassmaking to remove the green fint caused by iron impurities.

Application :
Electrolytic manganese dioxide is the excellent depolarizing agent for battery, it has the characteristics of large discharge capacity, strong activity, small volume, long service life etc., So it has become the critical component of the battery cathode mix in today's alkaline & lihtium ion batteries.
Manganese dioxide, mainly used as a depolarizer in dry cell batteries, is the most important non-metallic form of manganese. In either traditional alkaline and rechargeable battery cells, Manganese dioxide takes in electrons through a redox reaction, becoming Manganese III oxide. It also has applications in lithium-ion technologies.
It is also the primary precursor to ferromanganese, an alloy of iron used for its lower melting point and low cost.
It is black in appearance and used to color glass and ceramics, as well as for cave art and possibly body paint in prehistorical eras. Further uses include the purification of drinking water, and production of pure oxygen and chlorine
FAQ
DO YOU ACCEPT SAMPLE ORDER?
We accept sample orders. We will make samples before mass production, and after sample approved, we'll begin mass production. Doing 100% inspection during production, then do random inspection before packing.
2.HOW TO CONFIRM THE PRODUCT QUALITY BEFORE PLACING ORDERS?
You can get free samples for some products,you only need to pay the shipping cost or arrange a courier to us and take the samples. You can send us your product specifications and requests,we will manufacture the products according to your requests.
3.WHAT'S YOUR MOQ?
Our MOQ is 1kg. But usually we accept less quantity such as 100g on the condition that sample charge is 100% paid.
4.DO YOU SUPPLY PRODUCT REPORT?
Yes. We'll give you product analysis report before shipping.
5.IS THERE A DISCOUNT?
