Lithium primary batteries are still widely used in military, aerospace, medical, and civilian applications despite the omnipresence of rechargeable Li-ion batteries. However, these current primary chemistries are exclusively based on inorganic materials with high cost, low energy density or severe safety concerns. Here, a novel lithium-organic primary battery chemistry that operates through a synergetic reduction of 9,10-anthraquinone (AQ) and fluoroethylene carbonate (FEC) is reported. In FEC-presence, the equilibrium between the carbonyl and enol structures is disabled, and replaced by an irreversible process that corresponds to a large capacity along with methylene and inorganic salts (such as LiF, Li 2 CO 3 ) generated as products. This irreversible chemistry of AQ yields a high energy density of 1300 Wh/(kg of AQ) at a stable discharge voltage platform of 2.4 V as well as high rate capability (up to 313 mAh g −1 at a current density of 1000 mA g −1 ), wide temperature range of operation (−40 to 40 °C) and low self-discharge rate. Combined with the advantages of low toxicity, facile and diverse synthesis methods, and easy accessibility of AQ, Li-organic primary battery chemistry promises a new battery candidate for applications that requires low cost, high environmental friendliness, and high energy density.

Aqueous iron-ion batteries with reversible storage of Fe 2+ have undergone rapid development in recent years. Consistently throughout these studies, metallic iron is selected as the anode material. However, the large overpotential (250 mV) associated with the plating/stripping process of iron in aqueous solutions leads to unsatisfactory energy efficiency of the battery, although high capacity and Coulomb efficiency can be achieved. Herein, an iron-free anode material, 9,10-anthraquinone (AQ) is proposed in aqueous iron-ion batteries, which shows a low reaction potential and minimal polarization during storing iron ions. The organic anode exhibits favorable specific capacity of 106 mAh g −1 at 0.5 A g −1 and excellent cycling stability (92.6% retention after 500 cycles). In addition, an aqueous full iron-ion battery is constructed using AQ as the anode and 9,10-phenanthraquinone (PQ) as the cathode. The full battery demonstrates an enhanced energy efficiency of 72%, which is 206% higher than that of metal iron anode, and shows excellent cycling stability and Coulombic efficiency. This work provides a viable route to overcome the high polarization of metallic iron anode and promote the development of aqueous iron-ion batteries.

Temporally intermittent and spatially dispersed renewable energy sources strongly call for large-scale energy storage devices. Aqueous aluminum-ion batteries show great potential for application due to their safety and low cost. Thus far, however, the ideal full-battery configuration is beyond the scope due to shortcomings with regards to suitable anode and cathode materials. Herein, we report a pioneering aqueous aluminum-ion battery system consisting of a Prussian white cathode, 1 M Al2(SO4)3 aqueous electrolyte, and an organic 9,10-anthraquinone anode. The oxidation capability of the Prussian white cathode during the first charging allows for the fabrication of the full battery without pre-inserting aluminum ions, thus making the rocking-chair-type battery feasible. Importantly, the open-framework structure of the Prussian white and distinct enolization charge storage mechanism of 9,10-anthraquinone ensure fast reaction kinetics. The full battery exhibits cycling stability with a capacity retention of 89.1% over 100 cycles at 500 mA g–1, finishing a cycle in about 10 min. This work provides a pathway for developing rechargeable aqueous aluminum-ion batteries.

Graphical Go Organic ! A long-lifespan small-molecule organic sodium-ion battery is described. The battery is constructed using a 9,10-anthraquinone-2,6-disulfonate (Na 2 AQ26DS) cathode and sodium terephthalate (Na 2 TP) anode, and delivers a maximum discharge capacity of 131 mAh g −1 cathode in 0.5–3.2 V, maintaining an average value of approximately 62 mAh g −1 cathode over 1200 cycles (0.5 A g −1 , ≈4 C). An organic Na-ion battery is reported with a polyanionic 9,10-anthraquinone-2,6-disulfonate (Na 2 AQ26DS, 130 mAh g −1 ) cathode and the Na-intercalated state (Na 4 TP) of sodium terephthalate (Na 2 TP, 255 mAh g −1 ) as the anode. The resulting full cells deliver the maximum discharge capacity of 131 mAh g −1 cathode in 0.5–3.2 V, simultaneously maintaining the average value of ≈62 mAh g −1 cathode during 1200 cycles (0.5 A g −1 , ≈4 C). These results are among the best performing organic sodium-ion full cells reported to date.

A series of nanorod-like porous Pd/γ-Al 2 O 3 catalysts with controllable textural properties and enhanced catalytic performance in 2-ethyl-9,10-anthraquinone (eAQ) hydrogenation for H 2 O 2 preparation were successfully prepared via a facile sol–gel method using aluminum isopropoxide as aluminum precursor and eAQ as structure directing agent, sequential calcination and impregnation process with Na 2 PdCl 4 solution. The physicochemical properties of the catalysts obtained with different addition amounts of eAQ were comparatively characterized by XRD, TG–DSC, BET, TEM, CO-TPR, H 2 -TPR and H 2 –O 2 titration. The results show that addition of eAQ can not only effectively control the textural properties (surface area, pore volume and average pore size) of the catalysts, but also lower their reduction temperature of active metal. Importantly, the catalyst obtained with an addition amount of 4 wt% eAQ shows the highest hydrogenation efficiency of 10.28 g·L −1 , which is 37.3% higher than 7.49 g·L −1 of the catalyst obtained without eAQ.

Redox flow batteries have received wide attention because of their unique advantages such as high efficiency, long cycle life, low operating cost, and independent adjustment of energy power. In this study, five types of anthraquinone derivative organic redox couple were selected, and the surfaces of graphite felt were modified. When the number of functional groups is increased or the substitution position is closer to the carbonyl (C═O) groups, a more pronounced hindrance for the C═O reaction on the benzene ring is observed; thus, the electrochemical performance and reversibility decreases. Sodium 9,10-anthraquinone-2-sulfonate solution is the best organic redox couple in terms of both reversibility and electrochemical performance. It was also found that all the surface treatment methods of graphite felt are beneficial for improving their electrochemical performances. All these superior results demonstrate that the graphite felt treated under air exposure at 550 °C for 3 h exhibited the best electrochemical performance, which might be attributed to the increase in the content of C–OH functional groups.

Objective: To observe the antioxidative effects of N-(9,10-anthraquinone-2-ylcarbonyl) xanthine oxidase inhibitors (NAY) in vitro and in vivo models of hyperuricemia and explore the mechanism.Methods: A classical experimental method of acute toxicity and a chronic toxicity test were used to compare the toxic effects of different doses of NAY in mice. The hyperuricemia mouse model was established by gavage of potassium oxonate in vivo. After treatment with different doses of NAY (low dose: 10 mg/kg, medium dose: 20 mg/kg, and high dose: 40 mg/kg) and allopurinol (positive drug, 10 mg/kg), observe the levels of uric acid (UA), creatinine (CRE), and urea nitrogen (BUN) in urine and serum, respectively, and detect the activities of xanthine oxidase in the liver. The hyperuricemia cell model was induced by adenosine and xanthine oxidase in vitro. The cells were given different doses of NAY (50, 100, and 200 μmol/L) and allopurinol (100 μmol/L). Then the culture supernatant UA level of the medium was measured. The next step was to detect the xanthine oxidase activity in the liver and AML12 cells, and the levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), and NOD-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammatory factors in the kidney and serum of mice. Western blot was used to detect xanthine oxidase protein expression in mouse liver tissue and AML12 cells, ASC, Caspase-1, NLRP3, GLUT9, OAT1, and OAT3 protein expression in mouse kidney tissue and HK-2 cells. Hematoxylin–eosin staining was used to stain the liver and kidney tissues of mice and observe the tissue lesions.Results: NAY had little effect on blood routine and biochemical indexes of mice, but significantly reduced the serum UA level. NAY significantly reduced the level of UA in hyperuricemia mice and cells by inhibiting xanthine oxidase activity and reduced the levels of TNF-α, IL-6, and other inflammatory factors in serum and kidney of mice. NAY can inhibit inflammation by inhibiting the NLRP3 pathway. In addition, NAY can downregulate GLUT9 protein expression and upregulate OAT1 and OAT3 protein expression to reduce the UA level by promoting UA excretion and inhibiting UA reabsorption.Conclusion: These findings suggested that NAY produced dual hypouricemic actions. On the one hand, it can inhibit the formation of UA by inhibiting xanthine oxidase inhibitors activity, and on the other hand, it can promote the excretion of UA by regulating the UA transporter. It provides new ideas for the development of hyperuricemia drugs in the future.

Two new anthraquinone-organotin complexes [Ph 3 Sn(O 2 CC 14 H 7 O 2 ) · MeOH] · MeOH ( AQS01 ) and Cy 3 Sn(O 2 CC 14 H 7 O 2 ) ( AQS02 ) were synthesized and characterized by elemental analysis, IR, 1 H NMR, 13 C NMR, 119 Sn NMR, X-ray crystallography and thermo-gravimetric analysis. Incorporation of 9,10-anthraquinone with organotin successfully enhanced its anticancer activity. Interestingly, the anti-proliferative activity of AQS01 against CAL-27 cells in vitro was almost 10-fold that of mitoxantrone and 40-fold that of cisplatin. Flow cytometry showed that AQS01 could induce apoptosis and arrest cell cycle in S phase. UV–visible absorption spectrometry and molecular docking showed that AQS01 can be well embedded in the double helix of DNA. Moreover, AQS01 induced cell death by upregulating the expression level of the DNA damage protein γ -H 2 AX and activating the mitochondrial apoptotic signaling pathway (Bax/Bcl-2). Therefore, AQS01 can be used as a potential anticancer drug and has potential for further research.

Redox flow batteries (RFBs) are considered as promising candidates for large-scale energy storage. However, traditional RFBs based on toxic metal ions have deficiencies in resource utilization and environmental protection. Considering the corrosiveness of acidic and alkaline electrolytes and sustainability of energy storage devices, neutral aqueous organic redox flow batteries (AORFBs) have more development prospects. Herein, an AORFB is reported, using 9,10-anthraquinone-2,7-disulfonic salt (2,7-AQDS) and 1,4-dihydroxyphenylsulfonate potassium (HQS) as negative and positive electroactive materials, respectively. It is found that the anions in the neutral solution further affected the solubility and kinetics of the electroactive materials by affecting the hydrogen bond in the solution, and the Na 2 SO 4 solution showed the optimal comprehensive performance. Therefore, an all-quinone AORFB employing neutral Na 2 SO 4 electrolytes with a cell voltage of 0.9 V is constructed, which presented a capacity utilization of 70.1% and delivered stable cycling performance at 60 mA cm −2 . This work designs an innovative neutral all-quinone AORFB and points out how anions affect the properties of the electrolyte by affecting hydrogen bonds within the solution. These findings open a new avenue for the design and application of neutral all-organic aqueous RFBs.
