Hunan Coran Industry & Commerce Co., Ltd.

We are a professional manufacturer of battery materials in China. Our main products include activated chemical manganese dioxide Electrolytic manganese dioxide(emd)super-purity nanometer indium hydroxide [in(oh)3] and indium oxide(in2o3) powders.

Our acmd are used for zinc-manganese dry cells only, which are made from high grade natural mno2, processed by chemically reducing, diverging, Oxidizing, etc. In fact, they are composed of activated mno2 and chemical mno2, so they have the advantages as follows: Gamma-type structure characteristic, large specific surface area, good absorption and strong electrochemistry activity. Acmd are widely used in heavy-duty

Zn-mn dry batteries, owing to their excellent continuous and intermittent discharge properties. Using with emd or replacing some proportional emd(usuallyabout 30~60 per cent), you can reduce the production cost Of batteries and hold on the same behavior of your batteries.

At present in(oh)3 and in2o3 are very popularized as the first-choice corrosion inhibitor to substitute for mercury. Our super-purity nanometer indium hydroxide and indium oxide powders have the following advantages: Large specific surface area, good dispersion, excellent corrosion inhibition. So they are perfectly suitable for the requirements of the zero-mercury batteries.
