This invention discloses a wide-temperature-range, long-life sodium-ion battery electrolyte, its preparation method, and its applications. The invention uses sodium perchlorate as the sodium salt, synergistically with low-viscosity, low-melting-point methyl acetate to ensure high ionic conductivity of the electrolyte over a wide temperature range. Simultaneously, dimethyl sulfite and fluoroethylene carbonate synergistically construct an inorganic-rich SEI film, significantly improving interfacial stability and cycle performance. The Na||NVP battery, after reversible charge-discharge at 60°C, maintained a discharge specific capacity retention of 88.33% of the initial capacity after 400 stable cycles. Under low-temperature conditions, reversible charge-discharge at currents of 0.1C and 0.3C resulted in stable cycles of 300 and 380 cycles, respectively. The preparation method of this invention is simple, low-cost, easy to implement, requires minimal equipment investment, and is suitable for mass production.

The invention belongs to the technical field of self-assembled microsphere arrays, and particularly relates to a pore-adjustable and stable self-assembled microsphere array as well as a preparation method and application thereof. The microsphere array disclosed by the invention is self-assembled in a manner of combining electrostatic mediation and covalent coupling, and contact among the microspheres is guided by virtue of electrostatic interaction, so that guidance is provided for realizing controllable covalent coupling among the microspheres by virtue of Schiff base reaction. The combination of covalent coupling and electrostatic force can improve the flexibility of the microsphere array and the stability of the combination between the microspheres, so as to improve the stability of pores between the microspheres, reduce the collapse of the microsphere array, provide a good and controllable three-dimensional space for the creeping growth of cells, and facilitate the promotion of wound healing and growth. The self-assembled microsphere array is suitable for application modes such as smearing or injection, and the scene applicability is greatly improved.

A plasma cooling chamber spray structure for removing process waste gas from production equipment allows individual or mixed process waste gases to enter a dissociation chamber of a waste gas plasma processor via separate gas pipelines. A vertical plasma body is located in the center of the dissociation chamber, which, in conjunction with the introduction of working gas nitrogen, dissociates the tail gas containing the special gas generated in the dissociation chamber at high temperature. A cooling chamber is connected to the rear end of the dissociation chamber, and the cooling chamber has an outer cylinder connected to the dissociation chamber and a short section relative to the tail end of the heating flame section of the plasma body. An inner cylinder of an outer cylinder is characterized by having multiple annularly arranged spray nozzles on the inner edge surface of the outer cylinder, each spray nozzle spraying water onto the outer edge surface of the inner cylinder to provide water cooling in addition to air cooling for the cooling chamber. Because the entire cooling chamber is cooled earlier, the dissociation of nitrogen at high temperature is reduced, thus greatly reducing the generation rate of NOx (gaseous nitrogen oxides) in the cooling chamber. Consequently, the cooling chamber can be shortened, thereby reducing the overall length and installation cost of the plasma processor.

The present application relates to the technical field of food contact packaging material preparation, and discloses a preparation method of a food contactable heat preservation and insulation carton of spray coating aerogel. After the surface of a paper base material is cleaned and activated, a bottom coating layer containing a cellulose affinity group, a bio-based polysaccharide cross-linked heat insulation coating layer containing food contact grade silica aerogel particles and a food contact grade transparent protective layer are formed in sequence. The obtained carton can reduce the risk of migration of aerogel particle pulverization, maintain the stability of the paper base interface bonding, and form a heat preservation and insulation surface that can contact food.
