Lithium is one of the critical ingredients in lithium-ion electric batteries. It is light and allows a high voltage, making it a perfect energy-dense material for rechargeable batteries. Lithium assets like brines and hard rock are a known raw source of lithium.
The use of lithium in manufacturing of lithium-ion batteries for hybrid and electric vehicles, along with stringent environmental regulations, have strongly increased the need for its sustainable production and recycling. The required purity of lithium compounds used for the production of battery components is very high (> 99.5%).
Lithium assets like brines and hard rock are a known raw source of lithium. Raw lithium must be converted into a chemical the intermediates lithium sulfate or lithium chloride and then refined into a battery-grade product such as lithium hydroxide (LiOH) or lithium carbonate (Li2CO3) for use in battery manufacturing.
The source of lithium has traditionally dictated the refined form of lithium salt. Using current refining methods, brines (containing lithium chloride) have yielded lithium carbonate, whereas refinement from spodumene (lithium sulfate) can yield either lithium hydroxide or lithium carbonate.
Of these methods the product is typically lithium hydroxide, lithium chloride, lithium bromide, butyl lithium, and lithium carbonate which is the primary precursor for Li-ion batteries .

In this paper, we present a simple and efficient solvometallurgical process for the purification of technical-grade LiCl to a high-purity final solution product (> 99.5% of Li) that is suitable for further conversion into a battery-grade LiOH·H 2 O, for instance by an electrodialysis process [16, 21].
battery-grade lithium salts is key. At present, the need for lithium hydroxide monohydrate, LiOH·H 2O, is rapidly increasing due to the growing importance of Ni-rich NMC cathode materials. Production of LiOH has typically been an expensive two-step process, using LiCl brines to first produce Li 2CO 3 by precipitation with Na 2CO 3, then ...
