标题:碳酸盐基电解液中锂硫电池微孔碳结构的优化
摘要:在基于碳酸盐的电解质中开发合适的硫阴极材料是锂硫电池的重要研究课题.尽管几种微孔碳材料作为硫的主体显示出了这种效果,但是生产微孔碳的方法既不容易也不容易控制.此外,由于微孔碳在制造过程中的复杂性和局限性,很少有研究通过调节碳的不同微孔尺寸(0-2 Nm)对锂硫电池的碳酸盐基电解质的电化学行为的影响.主持人.在这里,我们展示了一种直接的碳化过程,即自我活化策略,该过程可以从碱配合物中为硫磺主体反应生成微孔碳.此外,通过改变先前络合物中的不同碱金属离子,所获得的微孔碳显示出超微孔的主要部分(<0.7 Nm,从54.9%到25.8%),这表明主体材料的微孔结构在限制硫分子中起着至关重要的作用.当评估为li-S电池的基于碳酸盐的电解质中的正极材料时,这种微孔碳/硫复合材料可提供高可逆容量,循环稳定性和非常好的倍率性能.

摘要:The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are independently any anionic ligand; n L and L 1 are any neutral electron donor ligand; and, n R and R 1 are each hydrogen or one of the following substituent groups: C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl. Optionally, the substituent group may be substituted with one or more groups selected from C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted with one or more groups selected from a halogen, a C 1 -C 5 alkyl, or a C 1 -C 5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R 1 is —CHCR 12 R 13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.

摘要:The present invention relates to a method for the synthesis of nanofluids including functionalization of carbon nanostructures through a new method comprising the addition of carbon nanostructures to water; ultrasonication of the solution; addition of persulfate salt and one or several metal hydroxides of the first column of the periodic table to the aqueous solution containing carbon nanostructure; re-exposing the solution to ultrasonic waves; and then, the separation of the functionalized carbon nanostructures from the solution and washing the carbon nanostructures with water to neutralize them and mixing the nanoparticles obtained from the previous step with the fluid. By presenting a new method for the synthesis of the functionalized carbon nanostructures with specific amount of functional groups and their application in the synthesis of nanofluids, an increase in the stability and thermal conductivity of nanofluids takes place.

摘要:The present invention relates to a method for the microwave synthesis of a lithium iron phosphate material, and specifically a method for the microwave synthesis of a lithium iron phosphate material using a waste battery is disclosed, the method specifically involving the following steps: (1) selecting a waste lithium iron phosphate battery, discharging same and then disassembling same to obtain a positive electrode sheet; (2) calcining the positive electrode sheet obtained in step (1) at 300-500°C for 1-10 h, taking same out when the temperature decreases to room temperature, mechanically vibrating the positive electrode sheet to make lithium iron phosphate fall off a current collector aluminum foil to obtain lithium iron phosphate powder; and (3) mixing the lithium iron phosphate powder, a lithium source, an iron source, a phosphorus source and a carbon source, ball milling same, then subjecting same to a microwave treatment for 10-100 s, and repeating the ball milling and microwave treatment steps until lithium iron phosphate particles are obtained. The process of the present invention is simple in operation, easy to control in process, lower in energy consumption, environmentally friendly, and does not produce secondary pollutants. Furthermore, the repaired lithium iron phosphate material can be reused for producing a lithium ion battery.
