    Advancing Mining Processes to Make Better Materials for Use in Lithium Ion Batteries

    American Manganese Inc has developed a low-cost, environmentally friendly hydrometallurgical process to recover manganese (Mn) from lower grade resources. American Manganese has applied for a patent for their hydrometallurgical process that produces electrolytic manganese metal with low energy and water consumption. American Manganese commissioned R&D contractor, Kemetco Research Inc to determine uses of Artillery Peak manganese resource material to generate high value alternative products. Chemical manganese dioxide (CMD) and lithiated manganese oxide (LixMn2O4) for use in rechargeable batteries were the areas researched.

    The research was successful in producing CMD from Artillery Peak resource material with low cation impurities and avoiding processing steps that are known to introduce metallic impurities in the final product. Cation impurities cause capacity fade, whereas metallic impurities are known to cause catastrophic failures (such as fire and explosions) in lithium ion batteries. Working rechargeable lithium ion coin cell battery prototypes were produced from the CMD material.

    This webinar will focus on the following key topics:

    • Catastrophic failure of Li Ion batteries caused by metallic impurities that may be introduced from the mining of raw materials
    • Conventional mining process to recover MnO2 used to make LiMn2O4
    • Research on a new mining process that avoids steps known to introduce metallic impurities to recover MnO2 used to make LiMn2O4
