Sustainable battery production with low environmental footprints requires a systematic assessment of the entire value chain, from raw material extraction and processing to battery production and recycling. In order to explore and understand the variations observed in the reported footprints of raw battery materials, it is vital to re-assess the footprints of these material value chains. Identifying the causes of these variations by combining engineering and environmental system analysis expands our knowledge of the footprints of these battery materials. This article disaggregates the value chains of six raw battery materials (aluminum, copper, graphite, lithium carbonate, manganese, and nickel) and identifies the sources of variabilities (levers) for each process along each value chain. We developed a parametric attributional process-based life cycle model to explore the effect of these levers on the greenhouse gas (GHG) emissions of the value chains, expressed in kg of CO2e. The parametric life cycle inventory model is used to conduct distinct life cycle assessments (LCA) for each material value chain by varying the identified levers within defined engineering ranges. 570 distinct LCAs are conducted for the aluminum value chain, 450 for copper, 170 for graphite, 39 for lithium carbonate via spodumene, 20 for lithium carbonate via brine, 260 for manganese, and 440 for nickel. Three-dimensional representations of these results for each value chain in kg of CO2e are presented as contour plots with gradient lines illustrating the intensity of lever combinations on the GHG emissions. The results of this study convey multidimensional insights into how changes in the lever settings of value chains yield variations in the overall GHG emissions of the raw materials. Parameterization of these value chains forms a flexible and high-resolution backbone, leading towards a more reliable life cycle assessment of lithium-ion batteries (LIB).

“…For WRP, an increase in mass percentage of P2O5 and the ratio of CaO/P2O5 with a decrease in the mass percentages of Corg and CO2 are observed. This due to a reduction of free carbonates and other impurities, these results contribute to improve the quality of WRP with an increase in solubility and chemical reactivity [10][11][12][13][14][15].…”

“…To meet the use standard of phosphate, several methods have been used for the enrichment, depending on the type of the ore, associated gangue minerals and the impurity concentrations [7][8][9][10][11]. These methods include gravity separation [12][13][14][15], magnetic separation [12], electrostatic separation [13], size reduction, screening [14], attrition, purification, classification, separation of heavy metals [15,16], calcination [16], acid leaching [17,18], direct flotation [19], [20], reverse flotation [21] and the combination of several of these methods.…”

The aim of the present work is to compare two enrichment processes of the Bouchane phosphate. The first one is the usual calcination of the raw phosphate and the second is the calcination of the washed raw phosphate. We investigated the variation of some physicochemical properties, namely the specific surface, the volume mass and the mass percentage of the main constituents of the calcination of phosphates such as Organic carbon (Corg), Carbon dioxide (CO2), Phosphorus pentoxide (P2O5), and Lime (CaO), during these processes as a function of time and temperature. For this purpose, different analysis techniques were used such as the granulometric analysis, the quantitative analysis by volumetric method and by inductively coupled plasma atomic emission spectroscopy (ICP-AES), the mineralogical characterization by X-ray diffraction and differential thermic analysis coupled with thermogravimetric analysis. We concluded that a pre-washing a raw phosphate is critical to improving the quality of phosphates. A calcination at 800°C for 30 minutes reduces mass percentages of organic carbon by 88.60% and 91.43%, carbon dioxide by 53.00% and 54.54%, while the masses of P2O5 is increased by 9.15% and 10.46%, for the calcined raw phosphate and the raw phosphate washed and then calcined, respectively. It follows that the second procedure favors the reduction of energy consumption, which, in turns, is subsequently beneficial to the environment since it decreases the emission of CO2 by improving the quality through increasing the chemical reactivity and solubility.

“…In the present scenario, the industries are in search of implementing novel, effective, and environmentfriendly methods for recycling of resources due to the massive depletion of natural mineral sources [5]. A comprehensive outlook on various methods used for the increasing manganese concentration in ores has been summarized by Singh et al [6]. Manganese occurs in nature and hardly exists in a pure and elemental state.…”

An overview on potential hydrometallurgical processes for separation and recovery of manganese

With rapid economic progress worldwide, the search for new resources for materials has become a priority due to mineral resource depletion. Enhanced requirements for manganese alloys and compounds for several commercial applications created a desperate demand for manganese recovery technologies from primary as well as secondary resources. The future demand for manganese alloys and compounds is expected to increase. The growing need of electrolytic manganese dioxide (EMD) for different battery usage in automobile and energy sectors could create a gap in the supply and demand of manganese. There is an urgent necessity for eco-friendly and efficient technologies to boost the production of manganese from low-grade ores as well as post-consumer products. The framework of effective leaching processes and proper solvent extraction techniques for the recovery of manganese could be a novel pathway to get a clean, green and healthy environment for a sustainable future in the automotive and energy segment where this metal has a significant contribution.
