Development of the green technologies and the transition to carbon-free energy are inextricably linked with the creation of new resource and energy storage. Lithium-ion batteries are the most widely used in both – portable electronic devices and electric vehicle batteries. Therefore, considerable attention of researchers is directed to the creation of effective technologies for recycling of spent batteries. This is due to the limited natural lithium resources, toxicity releasing into the environment, and ever-increasing cost. Recovery of Li+ ions by the hydrometallurgical methods makes it possible quite efficiently to process high-salt brines. However, the disadvantages of this technology include the large volumes of the resulting liquid effluents, its toxicity, and the difficulty of achieving a deep recovery degree of Li+ ions. Extraction is superior to hydrometallurgical methods in terms of the Li+ ions recovery efficiency. The high toxicity and cost of extracting agents make this approach unacceptable for industrial applications with low environmental and economic attractiveness. Currently, electrochemical methods are being actively investigated as a promising alternative, however, the first positive results were obtained only on a laboratory scale. Inorganic lithium-ion sieves are widely used as adsorbents of Li+ ions. The most effective selective adsorbents are developed on the basis of Li-Ti and Li-Mn spinels, which is due to the high capacity and affinity toward Li+ ions, and selectivity with the background of competing metal ions. At the same time, the low kinetics of adsorption-desorption, the complexity of adsorbents regeneration, as well as the low stability of the crystal structure of this ion-exchange materials are the main issues that limit their widespread application. The present work is devoted to the development of effective Li+ ions adsorbents based on Li2TiO3 spinel, study the relationship between the synthesis conditions, crystal and porous structure, and adsorption properties of obtained adsorbents. Samples of Li2TiO3 spinel were obtained by using hydrothermal, sol-gel, and solid-phase synthesis methods. Hydrothermal synthesis was carried out using precursors TiO2 and LiOH at 200°C for 10 h. Sol-gel synthesis was carried out by the self-combustion method. For solid-phase synthesis of Li-Ti spinel a stoichiometric mixture of TiO2 and Li2CO3 was preliminarily pressed into tablets under a pressure of 10 Mpa. All samples obtained by the above methods were calcined at 700°С for 5 h. The report includes the results synthesis and physicochemical properties of Li-Ti spinel adsorbents by using XRD, DTA-TG, FTIR, low-temperature nitrogen adsorption-desorption, SEM-EDX techniques. The main factors determine low kinetics of adsorption-desorption and optimal Li+ ions adsorption conditions, which make it possible to achieve the maximum theoretical Li2TiO3 spinel adsorption capacity, will be discussed.
