The present application provides an electrolyte and a sodium-ion battery. The electrolyte comprises a first additive, a second additive, and a third additive, wherein the first additive is selected from diglycolic anhydride, the second additive is selected from at least one of sodium difluorophosphate and sodium difluoro(oxalato)borate, and the third additive is selected from hexamethylene diisocyanate. The synergistic effect of the three additives reduces impedance in sodium-ion batteries, and improves sodium-ion battery cycle performance and high-temperature storage performance.

The invention discloses a novel method for synthesizing bisamide podand, and belongs to the field of organic synthesis. The method comprises the following steps: directly reacting diglycolic acid with secondary amine, carrying out gradient heating and reaction rate control in the reaction process, carrying out rotary evaporation, petroleum ether dilution and filtration after the reaction is finished, adding excessive nitric acid to generate a third phase, filtering and taking out the third phase, and carrying out petroleum ether washing, alkali washing, water washing and vacuum drying to obtain the bisamide podand. The method has the advantages of milder reaction conditions, few reaction steps, short reaction time, simple purification steps and higher purity and yield.

The invention relates to the technical field of degradable materials, in particular to environment-friendly degradable plastic and a preparation method thereof. According to the invention, 1, 3-butanediol, isophorone diisocyanate and stannous iso-octoate are added, so that a polyurethane prepolymer is prepared. 3, 5-dihydroxy benzaldehyde, diglycolic acid, the polyurethane prepolymer, terephthalic acid, adipic acid and catalysts tetrabutyl titanate and isocyanate are used as raw materials, and the easily degradable polyester is prepared. The high-strength antibacterial polyester is obtained by blending and banburying the easily degradable polyester, the chitosan and the antibacterial substance. Finally, high-strength antibacterial polyester, liquid paraffin, sodium dodecyl benzene sulfonate, an antioxidant and a plasticizer are added, and the environment-friendly degradable plastic film is prepared. The environment-friendly degradable plastic film prepared by the invention has good degradability, mechanical strength and antibacterial property, so that the environment-friendly degradable plastic film has a wide application prospect in the technical field of degradable materials.

A method of forming a diglycolamide includes heating a reaction solution including a diglycolic acid ester having the structure R5O—C(O)—CH(R3)—O—CH(R4)—C(O)—OR6, and an amine having the structure R1—NH—R2, to form the diglycolamide having the structure (R1)(R2)N—C(O)—CH(R3)—O—CH(R4)—C(O)—N(R1)(R2).
