Therefore, the development and utilization of the secondary cobalt and nickel metals will be a great potential to reduce environmental impacts of NCM production. The primary cobalt and nickel resources in China with lower grade and difficult mining led to the high energy consumption of these two kinds of raw materials. The environmental impacts of the CoSO 4 production and NiSO 4 production were the main contributors to that of the precursor production.
fine chemical upstream processes, an average organic solvent recovery rate of.
The energy consumption of the precursor production was 612MJ, accounting for 94.6% of the total energy consumption of NCM production. Increasing use of hazardous chemicals as raw materials, intermediates and. The results indicated that the precursor production contributed the most to environmental impacts in the NCM cathode material production. The main factors and sources causing environmental pressure were identified. The environmental impacts of the main processes were calculated. ask.openLCA is run by GreenDelta, the creators of openLCA. Receive guaranteed and prioritised professional support via GreenDelta's help desk. It is also the public support platform for openLCA, openLCA Nexus, data.openLCA and the LCA Collaboration Server. In this article, life cycle assessment of NCM cathode material production using coprecipitation method in China was conducted based on ReCiPe method. ask.openLCA is a question-and-answer (Q&A) website on Life Cycle Assessment (LCA). The NCM cathode material production process including the Li 2CO 3 preparation, precursor preparation and synthesis process of cathode materials is resource-and energy- intensive, thus it leads to relatively severe environment pollution. The nickel cobalt manganese ternary (NCM) cathode material is one of the important parts of power lithium battery.
