In this article, the hydrometallurgical processes for extraction of lithium from ores, brine, and battery recycling with sodium sulfate as a by-product are discussed. Alternative and environment-friendly processes to valorize sodium sulfate are reviewed.
Lithium-ion batteries (LIBs) are widely used multifunctional energy storage devices due to the advantages of considerable specific energy, long cycle life, and low charge loss in the stationary state [1].The annual production of cathode materials for LIBs is estimated to be 200,000 tons [2].This means that the demand for LIBs is proliferating, and the number of

5 天之前· The presence of sodium sulfate (Na 2 SO 4) in wastewater poses a significant challenge to lithium-ion battery recycling.Bipolar membrane electrodialysis (BMED) has been explored to address this issue by electrochemically removing Na 2 SO 4 while simultaneously producing sulfuric acid (H 2 SO 4) and sodium hydroxide (NaOH) through a bipolar membrane.
Before the disposal of lithium–cobalt batteries and lithium–manganese batteries, they must first be discharged to a voltage no greater than 0.5 V. Above 0.5 V, the batteries will catch alight

Sodium sulfate, a byproduct of conventional hydrometallurgical processes used to recycle lithium-ion batteries, poses substantial environmental concerns. These traditional methods involve the use of harsh chemicals to leach valuable metals from spent batteries, resulting in large quantities of sodium sulfate waste. This waste is not

Most battery materials are made in China, where firms often sell their sodium sulfate as a raw material for other products. However, the number of battery projects planned in Europe and North America, which don''t have industries to absorb this waste, is growing quickly. Some industry leaders worry that plans by these developers for discharging sulfate waste
Hydrometallurgical recovery of rare earth elements (REE) from NiMH battery waste can be performed using sulfuric acid leaching followed by selective precipitation as double salt (REENa(SO4)2·H2O) by adding Na2SO4 as a precipitating agent. The formed double salts can then be further converted with NaOH solution to form REE hydroxides. However, present

How can owners reuse, or eliminate, sodium sulphate waste streams from battery materials plants? The current batteries boom has driven a surge in the volume of sodium sulphate production, at a time when more stringent environmental regulations are making producers dispose of it in more responsible ways.

Recycling of sodium sulphate, which is a liquid effluent from traditional lithium refining, enables the regeneration of valuable chemical reagents for re-use in the refining process. This eliminates the entire chemical reagent supply chain and the associated emissions. The funding from CICE will enable NESI to progress the technology from pilot

In this article, the hydrometallurgical processes for extraction of lithium from ores, brine, and battery recycling with sodium sulfate as a by-product are discussed.
One emerging area where these activities occur is the production of lithium-ion battery chemicals in which sodium sulfates are formed because of cathode precursor co-precipitation. Several solutions for sulfate removal exist, but one option is to reuse the sulfate side stream in other processes to increase circular economy and atom efficiency.
One emerging area is the production of lithium-ion battery chemicals in which sodium sulfates are formed during the coprecipitation of cathode precursors. In this study, a waste sodium sulfate solution from battery chemical production was studied as an alkali activator in the production of AAMs.
However, the lithium extraction and recycling processes bring a challenge: the production of a significant amount of sodium sulfate. Sodium sulfate, a white crystalline type of salt, is a seemingly innocuous byproduct. It is used in various industries, from manufacturing detergents and textiles to glass and paper.
However, in all these lithium production processes, a significant amount of sodium sulfate is produced and there are no plans, except disposal, to deal with it.
(16) Further, the use of AAMs as adsorbents and catalytic materials in water treatment has been explored. (17,18) However, to the best of our knowledge, the use of a waste sodium sulfate solution from the battery industry in the preparation of AAMs has not been explored before.
Large amounts of metal sulfates are formed annually in industrial activities. Until now, there has been no cost-efficient technical method for the treatment of sulfate wastes. In this article, we present a study on the reuse of waste sodium sulfate solution from battery chemical production in the synthesis of alkali-activated materials (AAMs).
