Spent lithium nickel cobalt manganese oxide (NCM) batteries were managed through hydrometallurgy to recover the precursor materials. When using this data, consider the specific composition and purity of the recovered materials, as this may vary based on the recycling process. The data set is applicable only for the recycling of 48V, 12Ah NCM batteries using hydrometallurgy. It is important to ensure that assumptions made about energy consumption and recovery efficiencies are consistent with the specific methodologies used. Users should also consider the geographic relevance of the data and its alignment with local recycling regulations and practices.
