“…Therefore, some alternatives, such as column adsorption and diffusion dialysis are employed. [ 62 ] These methods employ either Li‐selective adsorbents (activated carbon or spinel type materials) or osmotic distillation membranes to achieve a high degree of saturation of LiCl in the aqueous solutions. Additionally, these Li‐enriched solutions can by further augmented in Li by ion exchange, sequential adsorption, or solvent extraction.…”

Lithium metal batteries (LMBs) are one of the most promising energy storage technologies that would overcome the limitations of current Li‐ion batteries, based on their low density (0.534 g cm−3), low reduction potential (−3.04 V vs Standard Hydrogen Electrode) as well as their high theoretical capacities (3860 mAh g−1 and 2061 mAh cm−3). The overall cell mass and volume would be reduced while both gravimetric and volumetric energy densities would be greatly improved. Their electrochemical performance, however, is hampered by the low efficiency at high current densities and continuous degradation, which are related, among other factors, to the properties of the lithium metal anode (LMA). Hence, the production and processing of LMAs is crucial to obtain the desired properties that would enable LMBs. Here, the conventional method used for the production of LMAs, which is the combination of extraction, electrowinning, extrusion, and rolling processes, is reviewed. Then, the advances in the different alternative methods that can be used to produce and improve the properties of LMAs are described, which are divided into vapor phase, liquid phase, and electrodeposition. Within this last method, the anode‐less concept, for which different approaches to the development of advanced current collectors are illustrated, is included.

Lithium aluminum layered double hydroxide chlorides (LADH-Cl) have been widely used for lithium extraction from brine. Elevation of the performances of LADH-Cl sorbents urgently requires knowledge of the composition−structure−property relationship of LADH-Cl in lithium extraction applications, but these are still unclear. Herein, combining the phase equilibrium experiments, advanced solid characterization methods, and theoretical calculations, we constructed a cyclic work diagram of LADH-Cl for lithium capture from aqueous solution, where the reversible (de)hydration and (de)intercalation induced phase evolution of LADH-Cl dominates the apparent lithium "adsorption−desorption" behavior. It is found that the real active ingredient in LADH-Cl type lithium sorbents is a dihydrated LADH-Cl with an Al:Li molar ratio varying from 2 to 3. This reversible process indicates an ultimate reversible lithium (de)intercalation capacity of ∼10 mg of Li per g of LADH-Cl. Excessive lithium deintercalation results in the phase structure collapse of dihydrated LADH-Cl to form gibbsite. When interacting with a concentrated LiCl aqueous solution, gibbsite is easily converted into lithium saturated intercalated LADH-Cl phases. By further hydration with a diluted LiCl aqueous solution, this phase again converts to the active dihydrated LADH-Cl. In the whole cyclic progress, lithium ions thermodynamically favor staying in the Al−OH octahedral cavities, but the (de)intercalation of lithium has kinetic factors deriving from the variation of the Al−OH hydroxyl orientation. The present results provide fundamental knowledge for the rational design and application of LADH-Cl type lithium sorbents.

“…At the present stage, lithium-ion batteries (LIBs) have become an important medium for rational and efficient use of energy. − Since the commercialization of LIBs, the market demand for lithium resources has been soaring year by year .

“…For example, sodium is abundant and widely distributed, which means that SIBs have low production costs. Most importantly, sodium has similar physical and chemical properties to lithium, and the working principle of SIBs is very similar to that of LIBs. , Until now, three traditional cathode materials, polyanionic frameworks, layered transition metal oxides, and ferrocyanide compounds, still dominate in the field of SIBs. − The open framework structure of polyanions enables them to have high structural stability, which can meet the deintercalation mechanism of Na + , and is expected to achieve ultrastable sodium-ion batteries .

Na 3 V 2 (PO 4 ) 3 has been attracting great interest from scholars owing to its high voltage platform and high energy storage capacity. However, its poor electronic conductivity and weak ion diffusion ability seriously restrict the application of its actual industrialization. In view of the above defects, Na 3+x V 2 (PO 4 ) 3 /C (x = 0, 0.2, 0.4, 0.6) cathode materials for sodium-ion batteries (SIBs) are prepared through a solid-phase method in this paper. The X-ray diffraction (XRD) results show that the Na-rich amount of x = 0.4 attains the upper limit of the solid solution of the Na-rich Na 3 V 2 (PO 4 ) 3 , and the "ultracapacity" effect reaches the maximum at this x value; the capacity is as high as 132.4 mAh/g, with remarkable cycle stability (96% capacity retention after 300 cycles). The results of density functional theory (DFT) calculations clearly explain that the reason for the excess sodium occupying the electrochemically active Na2 site is the reason for the ultracapacity. It is found through the electron paramagnetic resonance (EPR) test that excessive sodium caused some high-valent V to be reduced to low-valent V, which maintained the electrical balance of the crystal and the stability of the Na-rich solid solution structure. Through the X-ray absorption near edge structure (XANES) of the V element, it is found that the change of V valence during the charge and discharge process of the Na-rich Na 3 V 2 (PO 4 ) 3 solid solution is consistent with that of Na 3 V 2 (PO 4 ) 3 . Refined structural characterization by spherical aberration electron microscopy and ex situ XRD also prove that the Na-rich Na 3 V 2 (PO 4 ) 3 solid solution undergoes a phase transition during the charge−discharge process and can be reversibly recovered. These findings further prove that it is feasible to synthesize a new Na-rich Na 3 V 2 (PO 4 ) 3 solid solution with a stable structure, which makes Na 3 V 2 (PO 4 ) 3 a practical cathode material for SIBs having great potential in the future.
