Study on adsorption extraction process of lithium ion from West Taijinar brine by shaped titanium-based lithium ion sieves

Crown Ether Grafted Graphene Oxide/Chitosan/Polyvinyl Alcohol Nanofiber Membrane for Highly Selective Adsorption and Separation of Lithium Ion

“…In recent years, with people's increasing attention to environmental pollution and the continuous advancement of science and technology [1], electrification has gradually become a major trend in the development of the global automotive industry, coupled with the popularization of consumer electronics such as mobile phones, tablets, and computers [2]. Lithium, as the core material of electric vehicle power batteries and the key material of lithium-ion batteries for consumer electronics products, has broad development prospects [3]. The lithium material industry spans the three strategic emerging industries of new materials, new energy vehicles, and new energy in China [4].…”

“…For the case where the magnesium-lithium ratio is too high, the precipitant consumption is too large and the economy is poor. The solvent extraction method represents the most in-depth study of the neutral phosphorus-containing TBP extraction system, but it has not been industrialized because of the serious corrosion of TBP to the equipment and the easy dissolution during the stripping process [3]. The emerging electrodialysis technology also needs to be improved owing to research work such as membrane life and operating costs under long-term operating conditions [11].…”

Recent Advances in the Lithium Recovery from Water Resources: From Passive to Electrochemical Methods

“…[66,69] Lower adsorption values were also found when working with brines and the trend of higher adsorption in case of higher pH values, highlighted by Ooi et al [122] for LMO adsorbents, was confirmed for LTO adsorbents too. [59,60] Granulated adsorbents with either PVC or agar as binders were also tested in geothermal waters at higher temperatures. In this case, slightly higher adsorption capacities were reached with agar as binder.…”
