Prince makes a wide range of high quality manganese derivatives, salts, and oxides for the international battery market. Electrolytic manganese dioxide (EMD) is a critical component of the battery cathode mix in today’s alkaline and lithium ion rechargeable batteries. Lithium-ion battery materials become more critical as the world moves into the “mobility era”. Batteries will be needed in everything from consumer electronics to green vehicles. As such, improvements in cell performance often rely on quality raw materials.
