Abstract :

Rich-Ni cathode NCM811 can significantly enhance the energy. However, the higher Ni content easily leads to the thermal instability. In this study, the electrochemical and thermal performance of cylindrical 18,650 LiNi0.Co-8(0).Mn-1(0).O-1(2)/graphite batteries with different state-of-health (SOH) were investigated. The key factors considered for the performance include high temperature storage, surface temperature, impedance, heat generation power, material structure and morphology. The batteries show excellent cycle efficiency of 88.7%, 88.5% and 88.4% after 500 cycles with 0.5 C/1 C/2 C current, respectively. In short-term high-temperature storage, the voltage of 80%SOH battery is reduced by 0.09 V, and the H1 peak strength is significantly reduced in dQ/dV curves. The temperature rise show that the 80% SOH battery's maximum temperature rise up to 40.8 degrees C at 3 C. The state-dependent EIS analysis reveals a strong positive correlation between impedance growth and cycle aging, where R-hf (SEI resistance) and R-lf (charge transfer resistance) exhibit temperature-dependent escalation rates. Heat generation was quantitatively analyzed through DC internal resistance and entropy coefficient measurements, revealing significant SOH-dependent characteristics. The 80% SOH battery exhibits 10.3% higher maximum reversible heat power (1.202 W vs. 1.090 W) and 5.6% greater irreversible heat power (0.948 W vs. 0.898 W) compared to pristine cells (100% SOH). The findings in this work are important to evaluate their thermal behavior and promote the development of battery management systems.

Abstract :

By a carbon nanotube (CNT) spatially confined metal-catalyzed structural reconstruction, carbon nanofibers (CNFs) with a hollow, hollow-solid, solid graphite core, and CNT shell are prepared using nitrogen heterocycle (NHC) and polycyclic aromatic hydrocarbon (PAH) as carbon sources. The formation mechanism of CNFs with oriented graphene layers and enlarged intergraphene spacing is studied by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and selected area electron diffraction analysis. It revealed that this one-dimensional nanoconfined metal-catalyzed carbon rearrangement is totally different from the reported spatially localized metal-catalyzed graphitization of electrospun polymer and nanocasted carbohydrate nanofibers, as the graphene orientation, cavity volume, and interlayer distance of CNFs can be controlled by the carbon concentration-related competitive metal-catalyzed tip growth of latitudinal and longitudinal graphene layers from NHC and PAH. The unique CNF structure renders good electronic/ionic conductivity, abundant Li+ storage interlayer gaps, and robust mechanical durability, resulting in outstanding electrochemical properties as anodes in lithium-ion batteries. The optimum CNF anode delivers a stable discharge capacity of 475 mA h g-1 at 0.1 C, an extraordinary rate capability of 303 mA h g-1 at 5 C, and a remarkable long-term cycling stability of 378 mA h g-1 after 600 cycles at 1 C. This 1D nanoconfined metal catalysis synthesis could be useful for the development of efficient CNF anodes in many electrochemical reactions with a potential for industrial applications.

Abstract :

Traditional ionic conductive hydrogel was prepared by chemically crosslinking the polymer chains to form network. However, the chemically crosslinked ionic conductive hydrogel usually showed limited elongation at break and high hysteresis during stretching process. Here, a simple strategy of synthesizing fully physically crosslinked ionic conductive supramolecular hydrogel without chemical crosslinker was purposed. Hydrophilic salt not only act as the ion supplier, but also provide the spatial confinement effect to form the completely physically crosslinked hydrogel. Firstly, CaCl2 was used as the representative salt. The optimal PVA/PAM/CaCl2 ionic conductive hydrogel (PPC), showed excellent tensile performance (2400.3 +/- 140.63 %), anti-freezing performance (-28.8 degrees C), high conductivity (4.8 +/- 0.01 S/m), excellent stability at room temperature, low hysteresis, and high transparency. The conductivity of PPC showed no sensitivity to the tensile strain. This innovative combination enables PPC ionic conductive hydrogel to have extraordinary versatility. The flexible allsolid-state supercapacitor assembled with PPC ionic conductive hydrogel as the electrolyte has a high area specific capacitance (136.9 mF/cm2). The prepared supercapacitor can maintain good stability under certain tensile deformation (The capacitance retention rate was 87.7 % when stretched at 200 %). Moreover, other high hydrophilic salts including LiCl, ZnCl2, MgCl2 and AlCl3 were used to prepare ionic conductive PVA/PAM hydrogel to verify the universality of this preparation method.

Abstract&Keyword Cite

Abstract :

Battery lifetime prediction is critical to successfully introducing new products to the market, and a long testing time will affect the promotion of the product. In this paper, The prediction model of battery cycle life composed of cut-off voltages and state of health (SOH) is established based on an inverse power law equation to evaluate the NCM(811)battery. It is found that the capacity is more sensitive to the charge cut-off voltages (CCOV) than to the discharge cut-off voltages (DCOV). The capacity degrades to 67.3 % at 180th cycle in the range of 3-4.4 V, while it is 65.8 % at 380th cycle in the range of 2.5-4.2 V (the normal work voltage of battery is 3-4.2 V). The internal resistance and capacity degradation of the battery is analyzed by the incremental capacity curve and the hybrid pulse power characterization (HPPC) test. The error between prediction and measurement is less than 3 % within 400 cycles, and the model can predict the battery lifetime under different conditions (SOH, voltage). It helps to shorten the test time of new products and optimize the operating conditions of battery.

Multi-level structure-controllable NC-enveloped CoS/NiS@Cu2S yolk-shelled nanospheres as Pt-free catalysts for efficient hydrogen evolution in alkaline water/seawater SCIE

Abstract&Keyword Cite

Abstract :

Among many ways that can improve the electrolysis catalysts of seawater, designing the catalyst with hierarchical nanostructure has received extensive attention because it allows a larger surface area and more active sites. In this work, the NC-enveloped CoS/NiS@Cu2S catalyst with multi-level structure was successfully synthesized by using the complex of trithiocyanuric acid and copper as the metal dopant to coat the spherical Co-Ni precursor, and then by a straightforward one-step high-temperature self-vulcanization reaction. Trithiocyanuric acid not only facilitated the sulfurization of metal elements but also served as N and C source coated on the catalyst. This method constructed structure-controllable, multi-level, and yolk-shelled nanostructure in a facile manner, greatly increasing specific surface area, expanded mass transport channels, and enhancing the exposure of active sites. Besides, the coating of N and C elements significantly increased the electrical conductivity and electrochemical activity of the catalyst. As a result, CoS/NiS@Cu2S@NC exhibited excellent hydrogen evolution performance with the small overpotential of 105, 161, and 176 mV at 10 mA cm-2 in alkaline water, simulated alkaline seawater, and alkaline seawater, respectively. The present approach is proposed as an inspirational idea of the design of cobalt-nickel-copper-based multi-level structural nanomaterials as non-platinum electrocatalysts for hydrogen evolution in seawater.

Abstract :

Iron nitride, with a high theoretical capacity and excellent electrical conductivity, has emerged as a promising high-rate anode material for lithium-ion batteries (LIBs). However, its commercial viability is still hindered by poor cycling stability resulting from severe volume changes upon cycling. To address this shortcoming, Fe3N/N-doped multilayer graphene (Fe3N/N-mG) was prepared by Fe-catalyzed graphitization of phenanthrene and a post-nitridation process. The well-dispersed Fe3N nanocrystals, with a size of ca. 5-10 nm, were spatially sandwiched in the N-doped multilayer graphene with a controlled thickness of 3.5-10 nm and open pore channels, showing abundant accessible active sites, robust structural stability, and high electron/Li+ transportation ability (2.1 S cm-1, 2.39 x 10-12 cm2 s-1) when used as anode materials in LIBs. The optimum Fe3N/N-mG delivered exceptional capacities of 590 mA h g-1 at 0.1 C and 412 mA h g-1 at 5 C after 30 cycles, and a capacity retention of 530 mA h g-1 at 0.1 C after 600 cycles, surpassing the pure Fe3N, graphene, and many previously reported metal-nitride-based anodes. This work offers an in situ metal catalysis of polycyclic aromatic hydrocarbons and a subsequent post-nitridation strategy for the facile preparation of high-performance metal nitride/graphene electrodes for LIBs.

Abstract :

Transition metal oxides with the merits of high theoretical capacities, natural abundance, low cost, and environmental benignity have been regarded as a promising anodic material for lithium ion batteries (LIBs). However, the severe volume expansion upon cycling and poor conductivity limit their cycling stability and rate capability. To address this issue, NiO embedded and N-doped porous carbon nanorods (NiO@NCNR) and nanotubes (NiO@NCNT) are synthesized by the metal-catalyzed graphitization and nitridization of monocrystalline Ni(II)-triazole coordinated framework and Ni(II)/melamine mixture, respectively, and the following oxidation in air. When applied as an anodic material for LIBs, the NiO@NCNR and NiO@NCNT hybrids exhibit a decent capacity of 895/832 mA h g(-1) at 100 mA g(-1), high rate capability of 484/467 mA h g(-1) at 5.0 A g(-1), and good long-term cycling stability of 663/634 mA h g(-1) at 600th cycle at 1 A g-1, which are much better than those of NiO@carbon black (CB) control sample (701, 214, and 223 mA h g(-1)). The remarkable electrochemical properties benefit from the advanced nanoarchitecture of NiO@NCNR and NiO@NCNT, which offers a length-controlled one-dimensional porous carbon nanoarchitecture for effective e-/Li+ transport, affords a flexible carbon skeleton for spatial confinement, and forms abundant nanocavities for stress buffering and structure reinforcement during discharge/charging processes. The rational structural design and synthesis may pave a way for exploring advanced metal oxide based anodic materials for next-generation LIBs.

Abstract :

Green energy such as hydrogen energy has broad development prospects in promoting the adjustment of energy structure due to its advantages in cleanliness and efficiency. Hydrogen evolution reaction (HER) for water splitting can be used as a simple and effective avenue for hydrogen production. Platinum (Pt), a noble metal, has shown excellent catalytic performance as a conventional cathode catalyst for HER, but its high price has severely hindered its commercial application. Herein, a hollow nanorod array based Pt-free self-supporting electrode with a unique structure was developed for efficient hydrogen evolution reactions. This electrode was composed of a hollow ordered Ni-CoS2@MoS2 array as the main catalyst and a highly conductive Ti foil as a conducting substrate. In the synthesis process, ammonium tetrathiomolybdate was used as a multifunctional vulcanizing agent. Thanks to the unique structure of the hollow nanorods, the active ingredient was adequately revealed, making it possible to improve catalytic activity. This unique catalyst exhibited excellent HER performance at different pH values. Ni-CoS2@MoS2/Ti electrode exhibited high HER performance in alkaline, acidic, and neutral media, with overpotentials of 153, 192, and 196 mV at 10 mA cm -2 and Tafel slopes of 65.8, 67.8, and 93.3 mV dec-1, respectively.

One-pot preparation of strong, tough, frost-resistant and recyclable organohydrogels via Hofmeister effect and its application for electronic devices SCIE

Abstract&Keyword Cite

Abstract :

Conductive hydrogels have shown a great potential in the field of flexible electronics. However, it is difficult to combine high strength and high toughness in conductive hydrogels prepared by conventional methods, which limits their applications in various fields. In this work, we pioneered a facile and cost-effective strategy to prepare soy protein isolate/poly(vinyl alcohol) (SPI/PVA) conductive hydrogels with high strength, toughness, low- temperature resistance, and recyclability by introducing all the salts into the prescuor solution directly. To solve the problem of unable to directly introducing high concentration Na3Cit into the soy protein isolate/PVA solution, MgCl2 was used to alleviate the strong salting-out effect of Na3Cit. Thus the stable SPI/PVA/EG/MgCl2/ Na3Cit complex solution was obtained and the SPI/PVA/EG/MgCl2/Na3Cit (SPEMS) organohydrogel was prepared by the freezing/thawing process. The optimum tensile strength of the SPEMS organohydrogel was 1.1 +0.07 MPa, and the elongation at break was 701.3+23.67 %, respectively. Meanwhile, the ionic conductivity of the organohydrogel was as high as 1.7+0.01 S/m. Finally, the EG/H2O binary solvent system endowed the organohydrogel with excellent low-temperature resistance (freezing point of-19.4 degrees C). The strain sensors assembled with SPEMS organohydrogels were characterized by high sensitivity (GF = 3.2, strain range from 20 %-500 %) and long-term stability. The flexible all-solid-state supercapacitor assembled with SPEMS organohydrogel as the electrolyte and activated carbon as the electrodes has a high area specific capacitance (113.76 mF/cm2) and good cycling stability (capacitance retention of 81.62 % after 1,000 charging and discharging cycles) at room temperature.
