Background The removal of heavy metals is very important because of their nonbiodegradability and toxicity to the general population and environment. Adsorption is regarded as a promising approach for target pollutant removal due to its simplicity and economy. Methods Novel magnetic covalent organic framework (COF) composites (Fe 3 O 4 @TpPa-NO 2 ) consisting of a magnetic Fe 3 O 4 core and a TpPa-NO 2 COF shell are synthesized and developed as adsorbents for Pb(II) removal from aqueous solution. Significant findings The obtained composites exhibit superior adsorption performance (909.1 mg/g) and fast adsorption dynamics (adsorption equilibration time of less than 10 min) toward Pb(II). The experimental data for the adsorption of Pb(II) follow pseudo-second-order kinetic and Langmuir isotherm models. The superior performance of Fe 3 O 4 @TpPa-NO 2 for Pb(II) elimination is attributed to electrostatic and coordination interactions between the metal ion and functional groups (nitrogen and oxygen) of magnetic COF composites. The Pb(II)-loaded Fe 3 O 4 @TpPa-NO 2 can be easily regenerated by acid treatment. Furthermore, Fe 3 O 4 @TpPa-NO 2 demonstrates excellent reusability and maintains a high removal efficiency throughout five consecutive adsorption-desorption processes. Various COF-based magnetic adsorbents can be fabricated for specific pollutants due to the diversity in the structure and pore size of the COFs, which present attractive prospects for high-efficiency removal of contaminants in water treatment.

Advancing the high-voltage stability of the O3-type layered cathodes for sodium-ion batteries is critical to boost their progress in energy storage applications. However, this type of cathode often suffers from intricate phase transition and structural degradation at high voltages (i.e., >4.0 V vs Na+/Na), resulting in rapid capacity decay. Here, we present a Li/Ti cosubstitution strategy to modify the electronic configuration of oxygen elements in the O3-type layered oxide cathode. This deliberate modulation simultaneously mitigates the phase transitions and counteracts the weakening of the shielding effect resulting from the extraction of sodium ions, thus enhancing the electrostatic bonding within the TM layer and inducing and optimizing the O3–OP2 phase transition occurring in the voltage range of 2.0–4.3 V. Consequently, the cosubstituted NaLi1/9Ni1/3Mn4/9Ti1/9O2 exhibits an astounding capacity of 161.2 mAh g–1 in the voltage range of 2.0–4.3 V at 1C, and stable cycling up to 100 cycles has been achieved. This work shows the impact mechanism of element substitution on interlayer forces and phase transitions, providing a crucial reference for the optimization of O3-type materials.

Energy storage devices are progressively advancing in the light-weight, flexible, and wearable direction. Ti 3 C 2 T x flexible film electrodes fabricated via a non-contact, cost-effective, high-efficiency, and large-scale inkjet printing technology were capable of satisfying these demands in our previous report. However, other MXenes that can be employed in flexible energy storage devices remain undiscovered. Herein, flexible V 2 CT x film electrodes (with the low formula weight vs Ti 3 C 2 T x film electrodes) with both high capacities and excellent photoelectric properties were first fabricated. The area capacitances of V 2 CT x film electrodes reached 531.3–5787.0 μF⋅cm −2 at 5 mV⋅s −1 , corresponding to the figure of merits (FoMs) of 0.07–0.15. Noteworthy, V 2 CT x film electrode exhibited excellent cyclic stability with the capacitance retention of 83 % after 7,000 consecutive charge–discharge cycles. Furthermore, flexible all solid-state symmetric V 2 CT x supercapacitor was assembled with the area capacitance of 23.4 μF⋅cm −2 at 5 mV⋅s −1 . Inkjet printing technology reaches the combination of excellent photoelectric properties and high capacities of flexible V 2 CT x film electrodes, which provides a new strategy for manufacturing MXene film electrodes, broadening the application prospect of flexible energy storage devices.

Lithium-sulfur (Li-S) batteries are promising for energy storage due to their high theoretical energy density and specific capacity. However, the polysulfide shuttle effect severely limits their performance. In this study, two-dimensional (2D) Co 3 O 4 /CoSe 2 heterostructures were synthesized to enhance polysulfide adsorption and catalysis through synergistic effects. The Co 3 O 4 /CoSe 2 heterostructure exhibited strong adsorption and catalytic activity, significantly improving the battery’s reaction kinetics. At a 1 C rate, the initial discharge capacity reached 958.22 mAh g −1 , with a capacity decay rate of only 0.04 % per cycle over 2000 cycles. At a 2 C rate, the initial capacity was 909.89 mAh g −1 , with a decay rate of 0.06 % over 1400 cycles. Under high temperature conditions (60 °C), the battery delivered an initial capacity of 990.47 mAh g −1 , with a single-cycle decay rate of 0.1 % after 200 cycles. At a low temperature (10 °C), the initial capacity was 1039.1 mAh g −1 , with a decay rate of 0.1 % per cycle after 200 cycles. Additionally, with a high sulfur loading of 3.54 mg cm −2 , the initial capacity reached 1041.8 mAh g −1 , retaining 385.96 mAh g −1 after 200 cycles. These results demonstrate the effectiveness of the Co 3 O 4 /CoSe 2 heterostructure in mitigating the polysulfide shuttle effect and improving the performance of Li-S batteries, offering new opportunities for advanced energy storage systems.

Low cost and considerable theory specific capacity (∼1195 mAh g −1 ) make Sb 2 SnO 5 (SSO) material becoming a potential candidate for sodium-ions battery anodes. However, the low electronic conductivity and sluggish ions transfer kinetic has inhibited the practical applications. Herein, we demonstrate a novel Sn/Sb@SSO@PCFs composite using simple but effective electrospinning methods, which enable SSO nanoparticles embedded with Sn and Sb nanodomains in situ generation. The SSO was first reported as anode for sodium-ion batteries and in situ generation Sb and Sn nanocrystals domain around the SSO oxides . Different from existing tactics, the unique composite establishes a robust and efficient electrical contact between the SSO and the conductive Sb and Sn phases, enabling fast ions and electrons transfer across the electrochemical active SSO/Sb/Sn. Meanwhile, the composites offer an opportunity to compromise the challenges faced by each entity and enhance the overall performance by circumventing the weakness of individual SSO, Sn and Sb. As evidenced, the as-fabricated composite has unexpected electrochemical properties , including high capacity and long cycle stability with a retention rate of 83% after 450 cycles at 0.5 C. Combined with synergistic Na + ions storage of SSO/Sb/Sb and a simple and scalable manufacturing process, this study provides a new strategy to modulate material delivering high capacity and cycle stability for the next generation sodium ions batteries (SIBs).

Contact with trace heavy metal contaminants will also lead to extremely bad health influence on human body and aquatic life. Although various adsorbents have been synthesized for the recovery of heavy metal ions , most of them shows deficient adsorption capacity, sluggish uptake rate and low selectivity . In this study, a montmorillonite/polypyrrole (MMT/PPy) film was successfully synthesized by intercalating polymers PPy into the interlayer of MMT nanosheets for selective and rapid capture of Pb 2+ . The electroactive film has ultrahigh uptake capacity (1373.29 mg⋅g −1 ), which is much higher than most conventional Pb 2+ adsorbents. Meanwhile, it had an extreme selectivity towards Pb 2+ due to the MMT/PPy film can accurately identified Pb 2+ . Through characterization testing and data analysis, the selective and rapid uptake/release of Pb 2+ should be realized through three ways: (1) negatively-charged laminates of MMT can generate electrostatic attraction to Pb 2+ ; (2) -OH on the surface of MMT laminates can accurately identified and bonded with Pb 2+ (M-O-H↔ M-O-Pb); (3) PPy doped by PSS n- and protic acid can rapidly catch Pb 2+ (PPy + ·PSS n- +Pb 2+ +e - → PPy·PSS n- ·Pb 2+ ). Therefore, such a novel MMT/PPy nanocomposite film could has evident application prospect to remove Pb 2+ from various water bodies.

Organic redox-active materials are investigation hotspots for lithium ion storage due to their structural diversity and tunability. A large number of researches have focused on the organic materials of benzene para-substitution type. There are little investigations on benzene ortho-substitution type organic materials. Benzene ortho-substitution redox molecules are generally considered to be too close to the functional group to fully react, and conjugated structure is not as stable as that of para-substitution. However, we reported dilithium phthalate (Li 2 PA) anode active material for lithium ion battery . Interestingly, Li 2 PA anode has an excess capacity and reaches four-electrons reaction, and the lithium ions storage mechanism is explored: not only the two adjacent conjugated carbonyls can fully react, but also the rearranged benzene ring can accept two Li + ions. Li 2 PA anode has a high specific capacity of 674 mA h g −1 at 60 mA g −1 , with 91.7% capacity retention after 125 cycles (cycled for 4 months). Furthermore, it achieves high-rate capability, holding the specific capacity of 110 mA h g −1 at 4000 mA g −1 . This research shows that Li 2 PA can be used as organic active material for anode, opening up new possibility for organic anode development.

All-solid-state lithium–sulfur batteries (ASSLSBs) are promising for next-generation energy storage. However, the limited ionic and electronic conductivities of sulfur-based cathodes make them difficult to realize high sulfur content and high areal loading. Herein, a facile approach of in situ solid electrolyte formation is used to build ionic pathways in high sulfur loading cathodes. A precursor of P₂S₅ is introduced into the interior space of sulfur-carbon secondary particles, and its in situ reaction with the discharge product Li₂S forms lithium phosphorus sulfide solid-state electrolyte that establishes 3D ionic pathways within the cathodes. This approach not only activates more active materials but also boosts the overall ionic conductivity of the cathodes. The optimized cathode with a sulfur loading of 4 mg cm −2 can achieve a high specific capacity of 1340 mAh g −1 (based on sulfur mass) with 89% capacity retention after 100 cycles at 0.1C (1C = 1675 mA g −1 ). Even with a higher sulfur loading of 8 mg cm −2 , the cathode still demonstrates a very high active materials utilization with an areal capacity of 9.2 mAh cm −2 . The simple and effective method to realize high-performance sulfur cathode with built-in solid electrolyte ionic pathways would be useful for the further development of practical ASSLSBs.

Organic energy storage materials attract extensive attention as a potential alternative for the next generation of lithium ion batteries . However, most of the reported organic electrodes can not achieve a good balance among high capacity, high rate and long cycle-life. In this work, pyromellitic anhydride is adopted as a new anode material for lithium-ion batteries. It exhibits superior electrochemical performances compared to most of the reported organic electrodes. The pyromellitic anhydride anode is able to reversibly deliver a capacity of 1472.2 mAh g −1 at 30 mA g −1 . Even at an extremely high current of 30 A g −1 , the electrode still retains 562.7 mAh g −1 . After a 500 electrochemical cycles at 150 mA g −1 charge and 600 mA g −1 discharge, almost no capacity loss can be observed. The good electrochemical performance of the pyromellitic anhydride anode is because of its excellent lithium conductivity capability, as well as the stable solid electrolyte interface film formed on the electrode.

With the explosive growth of the electric energy storage industry, it is urgent to develop cathode materials with wide working voltage, high capacity, and low cost. Li-rich layered oxides have been in focus because they work stably in a voltage range of 2.0–4.8 V, deliver a reversible capacity of >300 mA h g−1 and can be Co-free. Nevertheless, the low initial Coulombic efficiency, inferior rate capacity, and rapid fading of the voltage and capacity stand in the way of their large-scale applications. Herein, we use citric acid to treat the surface of Li-rich layered materials. Citric acid not only dissolves the residual lithium compounds but also constructs a surface spinel layer with high crystallinity. In turn, the spinel layer protects the layered cathode from direct exposure to the electrolyte, improves the Li+ diffusion coefficient and suppresses the irreversible oxygen release. As a result, the citric acid-lithium rich sample possesses ultrahigh specific capacity (260 mA h g−1, while the pristine sample only possesses 207 mA h g−1) and initial Coulombic efficiency (>90%, 16% higher than that of the pristine sample). Even after 200 cycles, the citric acid-lithium rich sample possesses a high capacity of 202 mA h g−1 with a capacity retention of 81.7%. Furthermore, the voltage decay rate of the citric acid-lithium rich sample from the 10th to 200th cycle is nearly 1.42 mV per cycle, while that of the pristine sample is up to 2.06 mV per cycle. Briefly, this work provides a way to construct a surface stable oxygen frame, which is of great significance to the practical application of Li-rich layered oxide cathodes.

The development of high-performance binders is a simple but effective approach to address the rapid capacity decay of high-capacity anodes caused by large volume change upon lithiation/delithiation. Herein, we demonstrate a unique organic/inorganic hybrid binder system that enables an efficient in situ crosslinking of aqueous binders (e.g., sodium alginate (SA) and carboxymethyl cellulose (CMC)) by reacting with an inorganic crosslinker (sodium metaborate hydrate (SMH)) upon vacuum drying. The resultant 3D interconnected networks endow the binders with strong adhesion and outstanding self-healing capability, which effectively improve the electrode integrity by preventing fracturing and exfoliation during cycling and facilitate Li + ion transfer. SiO anodes fabricated from the commercial microsized powders with the SA/0.2SMH binder maintain 1470 mAh g −1 of specific capacity at 100 mA g −1 after 200 cycles, which is 5 times higher than that fabricated with SA binder alone (293 mAh g −1 ). Nearly, no capacity loss was observed over 500 cycles when limiting discharge capacity at 1500 mAh g −1 . The new binders also dramatically improved the performance of Fe 2 O 3 , Fe 3 O 4 , NiO, and Si electrodes, indicating the excellent applicability. This finding represents a novel strategy in developing high-performance aqueous binders and improves the prospect of using high-capacity anode materials in Li-ion batteries.

Nonaqueous redox flow batteries (NRFBs) have been regarded as promising large-scale electrochemical energy storage technology due to the wider solvent stable potential windows and greater selection of materials. However, the application of NRFBs is greatly limited considering the low capacity and high cost of active materials. In this work, we design and demonstrate a high-capacity polysulfide (PS)–polyiodide (PI) NRFB in Li-ion based 1,3-dioxolane (DOL) and 1,2-dimethoxyethane (DME) (v/v ∼ 1 : 1) organic electrolyte. The high solubility and low cost of PS (5 M) and PI (4 M) can achieve the high capacity and high applicability of NRFBs, which is attractive for realizing large-scale stationary energy storage. The highest volumetric capacity of 28 Ah L−1 based on a full cell is achieved with 1.5 M PS-4 M PI. The high coulombic efficiency (∼100%) and capacity retention (>99%) for 100 cycles in the PS–PI system is demonstrated by using a Li-ion conducting ceramic membrane. Voltage control is applied for both PS and PI to avoid the formation of irreversible solid Li2S and I2, which ensures the high stability of battery reaction. In situ UV-vis spectroscopy reveals the high reversibility of PS and PI in DOL/DME. A continuous flow mode test of the PS–PI system is also demonstrated to realize >300 hours stable cycling performance which implies good applicability for a long-term process. The successful demonstration of this high-capacity PS–PI nonaqueous system provides a new direction to promote the application of NRFBs in more fields.
