In this study, an alkaline earth metal doped molybdenum disulfide composite (AEM@MoS 2 , AEM = Ca, Sr, Ba) was presented, which can convert the desolvation process from non-spontaneous to spontaneous during heavy metal adsorption. The doping of MoS 2 by AEM not only increases the ratio of surface-active phases, but also modulates the energy band structure, so that Pb 2+ in solution was spontaneously exposed from the hydrated clusters and was more easily adsorbed on the AEM@MoS 2 surface. Among them, the maximum adsorption amount of Ba-MoS 2 reached 147.84 mg/g and the selectivity coefficient for Pb 2+ was as high as 254.58. The precipitation experiments yielded a Pb 2+ precipitation rate of 10.94 % under the condition of pure water, and molecular dynamics simulation (MD) yielded the diffusion coefficient of Pb 2+ being adsorbed on the surface of Ba-MoS 2 to be only 2.00 × 10 -4 Å 2 ·ps −1 . It was verified that it has excellent anchoring ability for Pb 2+ and effectively avoids the secondary pollution caused by desorption. This work can provide a new idea for improving the mechanism of the heavy metal hydrated ion adsorption process.

Resmetirom (MGL-3196) can form masses of solvates with a variety of solvents. In this study, a series of solvates, including those reported in patents and newly discovered solvates, were prepared by experimental screening. Hansen solubility parameters (HSPs) were used to investigate the formation rules of MGL-3196 solvates, and the results showed that the formation of MGL-3196 solvates was most related to the parameter Δ δ t . When the Δ δ t value between MGL-3196 and solvent was less than 14.23 MP0.5 a, MGL-3196 tended to form solvate with an accuracy of 84.09%. The precise crystal structures of six solvates and one solvent-free form (form A) were acquired by single crystal X-ray diffraction (SCXRD). After analyzing the structures of obtained solvates in-depth from the aspects of conformation, dimeric synthon, molecular packing, porosity and isostructuralism, the six solvates were classified into alcohol solvates (group 2), ester solvates (group 3) and other types of solvates (group 1). Generally, these three groups of solvates had completely different crystal structures. The solvates in group 1 and group 3 were channelized and isostructural in which solvents could be substituted without great influence on the structure, while in the alcohol solvates (group 2) solvents were fixed by strong hydrogen bonds to be a part of the crystal structure. Moreover, when solvates were desolvated, two metastable solvent-free forms (i.e., B and C) were crystallized and then transformed to form A through a structural rearrangement. The possible mechanisms for the phase transformation during different desolvation processes were finally proposed. All results shall provide an understanding and inspiration on the screening and production of polymorphic and pseudopolymorphic forms of MGL-3196 for the pharmaceutical industry.

Aqueous zinc-ion hybrid capacitors (ZIHCs) are a promising new type of energy storage device, but there is a plight that the unsatisfactory Zn 2+ storage capability of carbonaceous cathodes limits further application. To address this issue, desolvation strategy is employed to tailor the solvation sheath of Zn 2+ in the ultra-micropores (0.59 nm) nanospheres , where H 3 PO 4 acts as phosphorus source for forming C-P bonds and enhancing C=O bonds to further reduce the desolvation energy barrier. In practical application, a quasi-solid-state flexible ZIHC is constructed, which provides a battery-level energy density (293.4 Wh kg −1 ) at a power density (180 W kg − 1 ) and a remarkable capacity retention of 93.4 % after 10 000 cycles. Electrochemical analyses, DFT calculations and structural characterization reveal that ultra-microporous is proved to be a prerequisite for C-P/C=O that are expected to further deplete solvent molecules within a Zn 2+ solvation sheath. Also, the coupling effect between the strong adsorption of Zn 2+ by C-P/C=O and the hydrophobic effect of C-P play an important role in facilitating desolvation process. This work creates a precedent for the application of ultra-microporous carbon materials in ZHICs and provides a brand-new approach for breaking the bottleneck of the low energy density and poor lifespan of ZHICs.

High-performance sodium storage at low temperature is urgent with the increasingly stringent demand for energy storage systems. However, the aggravated capacity loss is induced by the sluggish interfacial kinetics, which originates from the interfacial Na+ desolvation. Herein, all-fluorinated anions with ultrahigh electron donicity, trifluoroacetate (TFA−), are introduced into the diglyme (G2)-based electrolyte for the anion-reinforced solvates in a wide temperature range. The unique solvation structure with TFA− anions and decreased G2 molecules occupying the inner sheath accelerates desolvation of Na+ to exhibit decreased desolvation energy from 4.16 to 3.49 kJ mol−1 and 24.74 to 16.55 kJ mol−1 beyond and below −20 °C, respectively, compared with that in 1.0 M NaPF6-G2. These enable the cell of Na||Na3V2(PO4)3 to deliver 60.2% of its room-temperature capacity and high capacity retention of 99.2% after 100 cycles at −40 °C. This work highlights regulation of solvation chemistry for highly stable sodium-ion batteries at low temperature.

Aqueous zinc-ion batteries (ZIBs) have received extensive attention due to the intrinsic advantages of high safety, low cost and environmental friendliness. But detrimental side reactions and dendrite problems resulting from high desolvation penalty and inhomogeneous Zn 2+ flux at the interface severely hindered their practical applications. Herein, a novel polyacrylamide-poly (ethylene glycol) diacrylate-carboxymethyl cellulose (PMC) hydrogel electrolyte is designed to overcome these obstacles through reducing the desolvation energy barrier and guiding the preferential orientation of Zn deposition simultaneously. Theoretical calculation and experimental results reveal that the desolvation activation energy of the PMC hydrogel electrolyte (36.42 kJ mol −1 ) is substantially lower than that of conventional ZnSO 4 aqueous electrolyte (62.31 kJ mol −1 ) due to the regulated Zn 2+ solvation structure. Based on the high binding energy between amide groups and Zn 2+ , polymer chains in PMC also serve as facile Zn 2+ transport channels to guide the uniform deposition behavior on the Zn (002) crystal surface, which is verified by the grazing incidence XRD analysis . Consequently, an ultra-long cycle life of 5000 h with a high coulombic efficiency of 99.5% is achieved by using the PMC hydrogel electrolyte. Considering the simple one-pot synthesizing method, the PMC hydrogel electrolyte provides new opportunities for developing practical ZIBs .

Rechargeable Mg batteries have gained great interest thanks to the abundant resources and high theoretical capacity of Mg metal anode. However, it suffers from severe passivation and extremely poor plating/stripping kinetics. Herein, a simple salt electrolyte system of Mg(OTf) 2 /MgCl 2 -DME is studied, and the poor Mg affinities on typical metal current collectors are revealed as the key factor for rapid cell failure. Accordingly, an interphase modification on Cu current collector by the in situ generation of a magnesiophilic Cu-thiourea (CuTU) complex is presented. It provides active sites for solvated Mg 2+ as well as Mg. This not only homogenizes Mg 2+ flux but also helps with the release of solvated species to lower the desolvation barrier. The high affinity with Mg further enables the dense and uniform growth of Mg deposits. Thanks to these merits, the facile and reversible plating/stripping of Mg is realized. As a result, the symmetric cells with Mg pre-deposited on CuTU-Cu electrodes stably operate for over 2600 h, which is a 34-fold increase in comparison to the standard Mg foil. Full cells coupling the Mg-CuTU-Cu anode and a PDI-EDA cathode with an N/P ratio of 3 deliver a high capacity of 251 mAh g −1 as well as stable cycling.

The large desolvation energy barrier of [Zn(H 2 O) 6 ] 2+ in aqueous zinc ion batteries (AZIBs) results in the undesirable [Zn(H 2 O) 6 ] 2+ formation, which leads to the uncontrollable water-induced side reactions and the intricately dendrites growth, thereby severely hindering the practical applications of AZIBs. Herein, we proposed boron-doped graphitic carbon nitride quantum dots (B-C 3 N 4 QDs) as an electrolyte additive for AZIBs. Experimental and theoretical calculations revealed that the doped B atoms could modulate the electron structure of the C 3 N 4 QDs, thus B-C 3 N 4 QDs played an enhanced catalytic role in efficiently decreasing the [Zn(H 2 O) 6 ] 2+ desolvation energy barrier to accelerate its desolvation kinetics in AZIBs, which led to releasing more free Zn 2+ , thereby suppressing side reactions and achieving highly reversible zinc plating/stripping to avoid the formation of zinc dendrites. Benefiting from these merits of B-C 3 N 4 QDs, the corresponding asymmetric Zn||Cu cell realized a high average Coulombic efficiency of 99.29 %. More importantly, the Zn||V 2 O 5 full cell with B-C 3 N 4 QDs still maintained a high specific capacity of ∼149.88 mAh g −1 at 5 A g −1 after 500 charging/discharging cycles, which was much higher than the battery without B-C 3 N 4 QDs at the same current density. This innovative design conception would inject new vitality to innovation of the low-cost, dendrite-free, and high-performance AZIBs and beyond.

Aqueous zinc-ion batteries (AZIBs) hold significant promise for energy storage; however, the high dissociation energy barriers of bulky hydrated zinc ions ([Zn(H2O)6]2+) induce uneven Zn deposition, leading to severe capacity degradation and a limited cycle life. Herein, an effective desolvation-enhanced zinc anode protective layer is constructed using Mo4/3B2–X nanosheets, in which the etching-induced metal vacancies and –F zincophilic sites endow the layer with a strong affinity for Zn2+ and effectively catalyze the desolvation of [Zn(H2O)6]2+. Experimental and theoretical calculations demonstrate that under the action of Mo4/3B2–X, the desolvation energy of [Zn(H2O)6]2+ can be effectively reduced from 38.99 kJ mol–1 of bare Zn to 27.67 kJ mol–1, significantly promoting greater flux and rapid diffusion of free Zn2+. As a result, this configuration achieves a dendrite-free Mo4/3B2–X-Zn anode with an ultralong cycling life exceeding 2000 h, which is 18 times that of bare Zn. Even under low-temperature conditions at 0 °C, the Mo4/3B2–X-Zn anode maintains stable cycling for over 2800 h with a low overpotential of 58 mV at 0.5 mA cm–2. Pairing with the KVO cathode, the full cell delivers a capacity of up to 291.2 mA h g–1 at 0 °C and the pouch cell achieves 256.9 mA h g–1 under a high mass loading of 9.5 mg cm–2, demonstrating promising commercial potential.

A novel organic polymer cathode namely poly(anthraquinone- alt -benzene) (PAQB, ∼190 mAh g −1 ) is intentionally designed and synthesized for sodium-ion batteries (SIBs). Full characterizations are carried out to define its polymer nature. Due to the strong π-π interaction of polymer main chains, the insoluble PAQB solid exhibits very efficient desolvation process against the solvated Na + ions in liquid electrolytes when compared to its insoluble dimer analogue (BAQB), leading to its highly impressive cycle stability and long material life. In half cells, PAQB can realize an average discharge capacity of 128 mAh g −1 during the ultra-long lifespan over 1 year. In the full cells with Na 3 Bi anode, the resulting PAQB II Na 3 Bi SIBs can realize the peak discharge capacity of 172 mAh g −1 cathode and stably hold 160 mAh g −1 cathode after 1000 cycles at 200 mA g −1 . To the best of our knowledge, PAQB is among the top cathodes currently reported for SIBs. And this work forwards a significant step for the application of organic electrodes in SIBs.

The application of Li metal anode in high energy density batteries is hindered by uncontrolled dendrites growth and rapid capacity decline. In this study, 4-aminobenzoic acid (4-ABA) is used as a multifunctional electrolyte additive to effectively stabilise Li anode and extend the cycling life of LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) cathode in carbonate electrolyte. It is found that 4-ABA facilitates the desolvation of Li + and increases the Li + transference number, leading to an increase in Li + flux on the surface of the Li anode, and finally the growth of Li dendrites is inhibited. The cycling performance of Li||Li symmetric cell is extended from < 400 h to more than 600 h at 1 mA cm −2 with a capacity of 1 mAh cm −2 . For the NCA cathode, 4-ABA is involved in the formation of a thin and uniform cathode electrolyte interphase (CEI) layer, which is conducive to inhibiting the corrosion of electrolyte on NCA cathode and reducing the dissolution of the transition metals Ni and Co. Thus, the electrochemical performances of the Li||NCA cell with the electrolyte containing 0.5% 4-ABA are significantly improved. In particular, the discharge capacity of the cells with the electrolyte containing 0.5% 4-ABA are still 164.9 and 150.7 mAh g −1 compared to only 126.3 and 116.0 mAh/g for the cells with the baseline electrolyte after 200 cycles at 1C and 5C. This study provides a simple and effective strategy for improving the electrochemical performances of Li anodes and NCA cathodes by optimising the electrolyte.

5-Sulfoisophthalic acid sodium salt (5-SSIPA) is a crucial intermediate for pharmaceuticals, pesticides, and polyesters. Several acidic groups lead to an unstable crystal structure. Two new polymorphs and three novel solvates were identified during the solvent screening. These crystals were characterized by powder X-ray diffraction, Fourier transform infrared, and scanning electron microscopy. The desolvation temperature of solvates was found to be higher than the boiling point of pure solvents, which tentatively indicated the existence of an interaction between solvents and 5-SSIPA molecules. The phenomenon that the three solvates gradually darkened with desolvation in the hot-stage microscopic images proved the occurrence of crystal desolvation. The non-isothermal desolvation kinetics of the 5-SSIPA solvates was analyzed and discussed.

Rechargeable aqueous zinc-ion batteries (RAZIBs) have attracted considerable attention for application in large-scale energy storage systems. However, the progress of RAZIBs has been hindered by the sluggish reaction kinetics and poor structural stability, which are closely associated with the desolvation process of hydrated Zn 2+ . To overcome these issues, an in situ interfacial polymerization strategy is proposed to uniformly germinate a polyaniline (PANI) layer on α-MnO 2 and form an organic–inorganic hybrid cathode (MnO 2 @PANI). Theoretical calculations and experimental characterizations disclose that the polyaniline layer equipped with hydrophilic functional groups can effectively trap the active water molecules to break the strong attraction between H 2 O and Zn 2+ , thereby facilitating the desolvation process of hydrated Zn 2+ , and regulating the Zn 2+ diffusion kinetics and electrode reaction kinetics on the cathode/electrolyte surface. Meanwhile, the irreversible phase evolution and dissolution of active species are largely suppressed due to the PANI shell protecting the α-MnO 2 from the attack of active water molecules. As a consequence, the organic–inorganic hybrid cathode exhibits 401.9 mAh/g after 200 cycles at a current density of 0.5 A/g and long-term durability over 1000 cycles at a current density of 2.0 A/g without irreversible phase transformation. This work provides insight into the regulation of the desolvation process for high performance aqueous energy storage systems.
