With the advancement of the global dual-carbon goal, green technology has become a priority in the energy field. Among energy storage technologies, all-solid-state batteries attract significant attention due to their high energy density, enhanced safety, and long cycle life. Poly(ethylene oxide) (PEO)-based polymer solid-state electrolytes are a research hotspot for next-generation lithium-metal batteries because of their flexibility, film-forming capabilities, and compatibility with lithium salts. In this study, cyclodextrin (β-CD) is employed as a green filler and combined with high-modulus polyacrylonitrile (PAN) fibers and plastic crystalline succinonitrile (SN) to synergistically enhance the electrochemical and mechanical properties of PEO-based electrolytes. The PAN/PEO/LiClO 4 /β-CD/SN electrolyte achieves an ionic conductivity of 6.5 × 10 −5 S cm −1 at 30°C and a lithium ion transference number of 0.33 at 80°C. PAN fiber significantly improves mechanical properties, achieving a tensile strength exceeding eight times that of the PEO/LiClO 4 membrane. In Li/Li symmetric batteries, the electrolyte demonstrates excellent interfacial stability for over 1100 h at 0.1 mA cm −2 . Additionally, the LiFePO 4 |PAN/PEO/LiClO 4 /β-CD/SN|Li coin cell exhibits an initial discharge specific capacity of 148 mAh g −1 at 80°C and 0.5C, retaining 70% capacity after 200 cycles. This study presents a novel design approach for utilizing green fillers in SPEs.

Thin and flexible composite solid-state electrolyte (SSE) is considered to be a prospective candidate for lithium-oxygen (Li-O 2 ) batteries with the aim to address the problems of unsatisfied safety, terrible durability as well as inferior electrochemical performance. Herein, in order to improve the safety and durability, a succinonitrile (SN) modified composite SSE is proposed. In this SSE, SN is introduced for eliminating the boundary between ceramic particles, increasing the amorphous region of polymer and ensuring fast ionic transport. Subsequently, the symmetric battery based on the proposed SSE achieves a long cycle life of 3000 h. Moreover, the elaborate cathode interface through the SN participation effectively reduces the barriers to the combination between lithium ions and electrons, facilitating the corresponding electrochemical reactions. As a result, the solid-state Li-O 2 battery based on this SSE and tuned cathode interface achieves improved electrochemical performance including large specific capacity over 12,000 mAh g −1 , enhanced rate capacity as well as stable cycle life of 54 cycles at room temperature. This ingenious design provides a new orientation for the evolution of solid-state Li-O 2 batteries.

High cost is one of the limiting factors in the industrial production of bioflocculant. Simultaneous preparation of bioflocculant from the contaminants in wastewater was considered as a potential approach to reduce the production cost. In this study, butyronitrile and succinonitrile were verified as sole nitrogen sources for the growth of strain K. oxytoca GS-4-08 in batch experiments. Moreover, more than 90 % of the mixed nitriles could be degraded in a continuous flow reactor, and the bioflocculant could be prepared simultaneously in the effluent. All the as-prepared bioflocculants exhibited high flocculation efficiencies of over 90 % toward Kaolin solution. FTIR and XPS results further unveiled that, the bioflocculant samples with abundance of carboxyl, amine and hydroxyl groups may play an important role on adsorption of Pd 2+ . The adsorption process could be well simulated by Freundlich model, and the K f values were as high as 452.8 mg 1−1/n l 1/n g -1 . The results obtained in this study not only confirm the technical feasibility for preparation of bioflocculant from various single nitrile and/or mixed nitriles, but also promise its economic feasibility.

A cross-linking succinonitrile (SN)-based composite polymer electrolyte (referred to as “CLPC–CPE”), in which vinyl-functionalized SiO2 particles connect with trimethylolpropane propoxylate triacrylate (TPPTA) monomers by covalent bonds, was prepared by an ultraviolet irradiation (UV-curing) process successfully. Vinyl-functionalized SiO2 particles may react with TPPTA monomers to form a cross-linking network within the SN-based composite polymer electrolyte under ultraviolet irradiation. Vinyl-functionalized SiO2 particles as the fillers of polymer electrolyte may improve both the thermal stability of CLPC–CPE and interfacial compatibility between CLPC–CPE and electrodes effectively. There is no weight loss for CLPC–CPE until above 230 °C. The ionic conductivity of CLPC–CPE may reach 7.02 × 10–4 S cm–1 at 25 °C. CLPC–CPE has no significant oxidation current until up to 4.6 V (vs Li/Li+). The cell of LiFePO4/CLPC–CPE/Li has presented superior cycle performance and rate capability. The cell of LiFePO4/CLPC–CPE/Li may deliver a high discharge capacity of 154.4 mAh g–1 at a rate of 0.1 C after 100 charge–discharge cycles, which is similar than that of the control cell of LiFePO4/liquid electrolyte/Li. Furthermore, the cell of LiFePO4/CLPC–CPE/Li can display a high discharge capacity of 112.7 mAh g–1 at a rate of 2 C, which is higher than that of the cells assembled with other plastic crystal polymer electrolyte reported before obviously.

Fabrication of a gel polymer electrolyte containing succinonitrile (GPE-SN) with high mechanical strength is quite challenging because the SN electrolyte always suppresses the formation of polymer networks during in situ polymerization. In this work, a mechanically robust GPE-SN was successfully prepared by using a solution immersion method. During fabrication, the paste-like SN electrolyte was transformed into a liquid SN electrolyte with low viscosity by heating at 50 °C and then infiltrated into the UV-cured highly cross-linked polyurethane acrylate (PUA) skeleton. The resulted GPE-SN film exhibits superior tensile strength (6.5 MPa) compared to the one (0.5 MPa) prepared by in situ polymerization (GPE-SN-IN). The high mechanical strength of the GPE-SN-IM film enables the LiCoO2/Li4Ti5O12 film battery to withstand 100-cycle folding without electrolyte damage and capacity loss. Besides, the GPE-SN presents a high ionic conductivity (1.63 × 10–3 S·cm–1 at 25 °C), which is comparable to GPE with a commercial liquid electrolyte (GPE-LE). Because of good thermal stability of the GPE-SN, the LiCoO2/Li cell with this electrolyte shows better charge–discharge cycling stability than that with GPE-LE at high temperature (55 °C). Thus, the GPE-SN prepared by our method could be a promising polymer electrolyte offering better safety and reliability for lithium-ion batteries.

Solid polymer electrolyte with high room-temperature ionic conductivity and safety is a potential solution to the application of lithium metal batteries. Succinonitrile (SN) is a promising candidate due to its non-flammability and good ionic conductivity. However, the high reactivity between SN and lithium limits the application. Herein, a ternary-lithium-salt (LiTFSI-LiDFOB-LiNO 3 ) system is proposed to regulate the behavior of SN-based electrolyte. SN is anchored in the polymer network generated by crosslinking ethoxylate trimethylolpropane triacrylate through in-situ thermal polymerization. The SN-based ternary-lithium-salt electrolyte (TSE) possesses high room-temperature ionic conductivity and excellent flame retardancy. The ternary lithium salts promote the formation of stable heterostructured composite SEI with enhanced mechanical strength and flexibility, which effectively inhibits SN-Li side reactions, improves interfacial compatibility, and ensures stable lithium plating/stripping. The Li|TSE|Li symmetric cell can stably cycle for 1800 h with small polarization of ∼10 mV. The LiCoO 2 |TSE|Li full cell delivers high capacity retention of 88.4 % at 4.4 V after 200 cycles. TSE is also suitable for various high-voltage cathodes, showing great promise in high-performance and high-safety solid-state lithium metal batteries. The excellent stability and electrochemical performance brought by ternary lithium salts provides a promising perspective into the development of room-temperature SN-based polymer electrolytes.

Solid polymer electrolytes such as poly(ethylene oxide) (PEO) are desirable in lithium batteries due to their high safety and excellent flexibility. However, low ionic conductivity and electrochemical stability of PEO hamper their applications. In this work, succinonitrile (SN) is added to the composite solid electrolyte (CSE) composed of PEO matrix and Li 6 . 4 La 3 Zr 1 . 4 Ta 0 . 6 O 1 2 filler to improve its ionic conductivity and electrochemical stability, thereby matching with ternary cathode materials. The results reveal that the ionic conductivity of CSE at 55 ∘ C can be increased by more than one order of magnitude with the addition of SN. And the CSE membrane containing 6 wt.% SN (CSE-6) exhibits the best electrochemical stability, which has improved the electrochemical window from 4.83 to 5.26 V. Compared with blank sample without the additive, the specific capacity of LiNi 0 . 5 Co 0 . 2 Mn 0 . 3 O 2 /CSE-6/Li is increased from 15.6 to 154 mAh ⋅ g − 1 , and exhibits relatively optimal cyclic stability in a range of solid-state batteries with different SN contents. It is expected that the results of this study will provide a reference for the application of PEO-based CSEs in high-voltage solid lithium batteries.

The development of solid electrolytes is a key step to break through the technical bottleneck of lithium batteries and obtain lithium batteries with high safety and high energy density. Combining the advantages of both inorganic and organic solid electrolytes, the form of inorganic fillers for composite solid electrolytes is extended from nanoparticles, nanofibers to a 3D matrix. In this study, a porous Li6.4La3Zr1.4Ta0.6O12 (LLZTO) ceramic framework was fabricated by adding a pore-forming agent, which was then infiltrated by succinonitrile (SN)-LiTFSI to take full advantage of the inorganic and organic parts of the composite electrolyte. The interconnected porous structure allows continuous ion transport pathways in both parts. The effect of the porosity, namely the amount proportion of inorganic and organic materials, on the electrochemical performance of composite electrolytes was investigated by regulating the amount of pore-forming agent. The presented composite solid electrolyte achieves a very high ionic conductivity of 1.08 × 10−3 S cm−1 at 30 °C, while it is stable up to 5.1 V at room temperature. The repeated lithium stripping/plating is stable over 250 h without short circuit.

To address the issues of the gel polymer electrolytes caused by solvents, like Propylene Carbonate (pc) and Ethylene Carbonate (ec), regarding cycling stability and safety, we prepared solvent-free PMMA-based solid polymer electrolytes using succinonitrile as a plasticizer (SN-PMMA) through the blade coating method. The mechanism of SN additives on dissociation of LiClO 4 and electrochemical properties was characterized using Fourier transform infrared spectroscopy, electrochemical impedance spectroscopy, and other structural investigation methods. The results indicated that SN is distributed uniformly in the PMMA matrix with high additive concentrations, and the nitrile group, which possesses strong polarity, effectively promoted the dissociation of lithium salt. The solvent-free SN-PMMA exhibits excellent ionic conductivity of 0.58 mS cm -1 and good thermal stability. The solid Electrochromic devices (ECDs) prepared with SN-PMMA and WO 3 via thermal laminating process maintain 90.8 % modulation amplitude after 500 cycles, as well as good electrochromic performance, where the optical modulation amplitude is 62.1 % at λ = 633 nm, the coloring efficiency is 53.77 cm 2 C -1 , and the response time is 23.8 s/38.1 s for bleaching/coloration, respectively. These findings confirm the feasibility of using SN as a substitute for traditional solvents and provide a new pathway for developing solid-state polymer electrolytes with enhanced safety and superior electrochemical performance.

A critical barrier to commercializing solid-state batteries lies in the inadequate performance of existing solid electrolytes, particularly their poor conductivity at room temperature and unsatisfactory long-term stability. In this context, a self-healing composite solid electrolyte based on succinonitrile (SCN) reinforced with lithium lanthanum titanate (LLTO) is introduced. Leveraging the increased interfacial lithium-ion (Li + ) transport channels in composite systems, the resultant LLTO-enhanced SCN electrolyte demonstrates remarkable ionic conductivity of 2.5 mS cm −1 at room temperature. The insight into the transport mechanism of Li + was provided using density functional theory. In addition to its superior conductivity, the electrolyte also exhibits excellent anodic stability, with an electrochemical oxidation potential reaching 5.1 V. Furthermore, LLTO effectively mitigates the inherent instability of SCN-based electrolytes while circumventing undesired side reactions. The self-healing properties enable autonomous repair of defects in the electrolyte, thereby enhancing battery safety characteristics. Consequently, symmetric Li cells demonstrated stable cycling for 1800 h at 0.1 mA cm −2 . Notably, the Li||LiFePO 4 cell retains 100 mAh g −1 of capacity at 1.0C after 1100 cycles at room temperature. The pouch cell further underscores the long-cycle durability and safety characteristics, with over 80 % capacity retention following 530 cycles. The investigation indicates that the LLTO-enhanced SCN electrolyte holds strong potential for the commercial application of solid-state lithium metal batteries under ambient conditions.

Solid-state electrolytes with high room temperature ionic conductivity , broad electrochemical window, and favorable thermal stability are crucial for the practical application of all-solid-state lithium-metal batteries. Here, a novel succinonitrile (SN)-based composite solid-state electrolyte (SN-CSSE) is fabricated directly inside the glass-fiber (GF) membrane via in-situ thermal-crosslinking ethoxylate trimethylolpropane triacrylate (ETPTA) monomer , coupled with the liquid SN-based electrolyte.

The coin full cells equipped with high-voltage LiCoO 2 (LCO) and modified Li metal anode deliver excellent interfacial stability, cycling reversibility , and rate capability. Moreover, the LCO/SN-CSSE/Li pouch cell exhibits more superior thermal stability than that of cell with commercial carbonate-based electrolyte during thermal shock test.

Solid-state lithium metal batteries with high energy density and safety have gained increasing attention due to their potential applications. However, the practical use of solid electrolytes is hindered by several challenges. These include poor compatibility at the electrode–electrolyte interface, low ionic conductivity at room temperature, and fast capacity degradation. To address these issues, here we propose ternary strategies by in-situ cross-linked plastic crystal electrolyte (in-situ PCE) based on succinonitrile (SN). Through the in-situ polymerization of SN with polyacrylonitrile/poly(vinylidene difluoride) (PAN/PVDF) nanofibers separator, excellent mechanical strength and compatibility at the electrode–electrolyte interface are achieved. The cross-linked structure of thermally polymerized ethoxylated trimethylolpropane triacrylate (ETPTA) immobilizes the SN molecule, preventing its contact with the lithium metal and inhibiting irreversible side reactions. Additionally, a LiF-rich passivation layer is employed to further protect the SN at the electrolyte-lithium metal interface. The dual protection from ETPTA and LiF offers excellent stability to lithium. Hence, the in-situ PCE exhibits high ionic conductivity (0.79 mS cm −1 at 30 °C) and wide electrochemical window (4.56 V, vs Li + /Li). The cells exhibit excellent cycling stability and high-rate performance. LiFePO 4 //Li cells retain 96.6 % capacity after 1000 cycles at 10C rate. This study provides valuable insights into the development of high-performance solid-state electrolytes.
