Investigation of fluorinated ether-containing electrolytes for high energy-density nickel-rich LiNi0.8Co0.1Mn0.1O2 electrodes

Nickel-rich LiNixCoyMn1-x-yO2 (x >= 0.6, NCM) materials and in particular LiNi0.8Co0.1Mn0.1O2 (NCM811) are considered as the most potential candidates for utilization in the next-generation of high-energy-density lithium-ion batteries (LIBs). However, the NCM811 materials encounter capacity fading during cycling, originating mainly from detrimental positive electrode-electrolyte interface changes. Here, to decrease electrolyte oxidative decomposition during NCM811 cycling process, we select a partially fluorinated ether, such as 1,1,2,2- tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) and 1,1,1,3,3,3-hexafluoroisopropyl methyl ether (HFPM), as a co-solvent for fluoroethylene carbonate (FEC)-based electrolytes and investigate theirs physicochemical and electrochemical performances in great details for their applications in NCM811 materials. Compared to the FEC-based electrolyte solution without a fluorinated ether co-solvent, the electrolytes with a fluorinated ether co-solvent exhibits an obviously improved cycling and rate properties of the Li/NCM811 cells cycled between 2.7 and 4.3 V. This work also shows that the TTE solvent is prone to both suppress the decomposition of FEC to stabilize the FEC-based electrolyte solution, and be reduced and form a stable interface layer in the highly reactive Li surface.

Developing improved electrolytes for aqueous zinc-ion batteries to achieve excellent cyclability and antifreezing ability

Due to their low cost, high safety, environmental friendliness, and impressive electrochemical performances, aqueous zinc-ion batteries are considered promising alternative technologies to lithium-ion batteries for use in large-scale applications. However, existing aqueous zinc-ion batteries usually suffer from poor cyclability and cannot operate at subzero temperatures. Herein, to solve these problems, the electrolyte in aqueous zinc-ion batterie is optimized by adding the appropriate amounts of diethyl ether and ethylene glycol. Results show that the addition of 1% diethyl ether contributes to the best cyclability at 25 degrees C. Furthermore, the addition of 30% ethylene glycol results in the best electrochemical performances at 0 and – 10 degrees C. This significant performance improvement at low temperatures is ascribed to the high ionic conductivity of the modified electrolyte and the low charge transfer impedance of the battery with the modified electrolyte at 0 and -10 degrees C. It is also shown that the modified electrolyte can decrease the nucleation overpotential of zinc plating, enhance the interfacial stability between the zinc metal and electrolyte, suppress the zinc dendritic growth and side reactions, and decrease the self-corrosion rate of the zinc anode. This work offers a facile strategy to realize aqueous zinc-ion batteries with excellent cyclability and antifreezing ability and may inspire research on other aqueous energy storage systems.

Synthesis, characterization, and photoinduced deformation properties of a series of azobenzene-containing poly(arylene ether)s

The photoinduced deformation properties in azobenzene-containing polymers can convert light energy into mechanical energy. At present, there are few types of photoinduced deformable polymers based on azobenzenecontaining high performance polymers, and new types of high performance azobenzene-containing polymers need to be developed. Here, a series of azobenzene-containing poly (arylene ether)s with various azobenzene contents were synthesized. These azobenzene-containing polymers showed high glass transition temperatures and high thermal stabilities. The photoisomerization behavior and the photoinduced deformation behavior of these azobenzene-containing polymers were studied upon exposure to a 442 nm linearly polarized laser and a 532 nm linearly polarized laser, respectively. Both of the photodeformation rate and the maximum photoinduced bending angles of the polymers increased with increasing azobenzene content. To our knowledge, it is the first report on photoinduced deformation properties of azobenzene-containing poly (arylene ether)s. In addition, the photoinduced bending rate and maximum photoinduced bending angle of the cantilever under 442 nm laser excitation were higher and larger than that under 532 nm laser excitation, respectively.

Nicotinamide Mononucleotide Restores the Meiotic Competency of Porcine Oocytes Exposed to Ethylene Glycol Butyl Ether

Ethylene glycol butyl ether (EGBE), a type of glycol ethers, is a common chemical used in both industrial and household products. Increasing animal studies have indicated that it produces reproductive problems, such as testicular damage, reduced female fertility, death of embryos, and birth defects. However, how it influences the female germ cells has not yet determined. Here, we found that EGBE exposure resulted in the defective porcine oocyte maturation via disruption of cytoskeleton dynamics, showing the abnormal spindle assembly, chromosome alignment, and actin organization. Meanwhile, EGBE exposure perturbed the mitochondrial distribution and function, leading to the accumulation of reactive oxygen species (ROS) and generation of DNA damage and apoptosis. Of note, nicotinamide mononucleotide (NMN) supplementation rescued the meiotic defects caused by EGBE exposure via restoring NAD(+) level and mitochondrial function and thus eliminating the excessive ROS. Taken together, our observations illustrate that NMN supplementation is an effective strategy to protect oocyte quality against environmental pollutant-induced deterioration, contributing to improve the animal and human fertility.

Exploring chemical kinetics of plasma assisted oxidation of dimethyl ether (DME)

Chemical kinetics of plasma assisted oxidation of dimethyl ether was investigated by photoionization molecular beam mass spectrometry (PI-MBMS) and kinetic modeling. A series of hydrocarbon and oxygenated intermediates, especially some fuel-specific oxygenated intermediates including methyl formate, ethyl methyl ether and dimethoxymethane, were identified by the measured mass spectra and photoionization efficiency (PIE) curves. The quantification results displayed two main change patterns of species mole fractions with increasing oxygen, indicating the different dominating formation pathways. In addition to the oxygenates, C1 and C2 hydrocarbon intermediates were observed at low temperatures in the DME/O-2/Ar and DME/Ar plasma systems, while the formation of these intermediates usually occurs at temperatures higher than 800 K in the thermal oxidation of DME. A kinetic model containing gas-phase reactions and plasma reactions was developed. The model analysis suggests that both hydrogen abstractions and plasma reactions involving electron/Ar*/O(D-1)/Ar+ contribute to the fuel consumption. The subsequent reactions of the resulting CH3OCH2, CH3O and CH3 lead to the yield of the observed hydrocarbons and oxygenates. The experimental results together with kinetic modeling indicate that the fuel and fuel radical may decompose into methyl radical, oxygen atom and formaldehyde directly, which account for the under prediction of formaldehyde and the observation of oxygenates with moderate concentrations in the DME/Ar plasma.

Competitive specific ion effects in mixed salt solutions on a thermoresponsive polymer brush

Hypothesis: Grafted poly(ethylene glycol) methyl ether methacrylate (POEGMA) copolymer brushes change conformation in response to temperature (‘thermoresponse’). In the presence of different ions the thermoresponse of these coatings is dramatically altered. These effects are complex and poorly understood with no all-inclusive predictive theory of specific ion effects. As natural environments are composed of mixed electrolytes, it is imperative we understand the interplay of different ions for future applications. We hypothesise anion mixtures from the same end of the Hofmeister series (same-type anions) will exhibit non-additive and competitive behaviour. Experiments: The behaviour of POEGMA brushes, synthesised via surface-initiated ARGET-ATRP, in both single and mixed aqueous electrolyte solutions was characterised with ellipsometry and neutron reflectometry as a function of temperature. Findings: In mixed fluoride and chloride aqueous electrolytes (salting-out ions), or mixed thiocyanate and iodide aqueous electrolytes (salting-in ions), a non-monotonic concentration-dependent influence of the two anions on the thermoresponse of the brush was observed. A new term, delta, has been defined to quantitively describe synergistic or antagonistic behaviour. This study determined the specific ion effects imparted by salting-out ions are dependent on available solvent molecules, whereas the influence of salting-in ions is dependent on the interactions of the anions and polymer chains.
