摘要:
A double-center quaternary ammonium salt ion liquid having the structural formula (I), wherein n=2, 3 or 6, Y− is BF4−, PF6−, (FSO2)2N−, (CF3SO2)2N− or CF3S3−. Also provided is a method for preparing a double-center quaternary ammonium salt ion liquid. The double-center quaternary ammonium salt ion liquid has high stability, and thus an electrolyte containing the double center quaternary ammonium salt ion liquid has a high decomposition voltage.

摘要:
A solid electrolyte battery comprises a positive plate (1), a negative plate (2), several composite electrode plates (3) and several solid electrolyte (4), wherein the number of the solid electrolyte (4) is one more than the number of the composite electrode plates (3). The positive plate (1) and the negative plate (2) are spaced oppositely, the composite electrode plates (3) are between the positive plate (1) and the negative plate (2), and both sides of the composite electrode plates (3) are laminated with the positive plate (1) and the negative plate (2) by the solid electrolyte (4), respectively, the structure of the solid electrolyte battery is formed. There is the solid electrolyte battery according to the invention, because the all surfaces of the positive plate (1), the composite electrode plates (3), the negative plate (2) are coated by the positive active material and/or negative material which may form the positive and negative capacitor structures, the positive active material and the negative active material can form good layered laminate structure with the solid electrolyte (4), thus internal resistance of battery is greatly reduced, so as to benefit migration of ions, therefore capacity of battery is improved.
摘要:
A Pt/graphene catalyst comprises graphene as carrier, and Pt loaded on the graphene. The use of graphene as carrier for the catalyst takes advantage of the ion effect and two-dimensional ductility of graphene, which increases the stability of the catalyst. The catalyst is prepared by a reverse micelles system method which provides a micro-environment (i.e. water-in-oil microemulsion), so that the particle size of the resulting nano-particles can be regulated easily and is more uniformly distributed. The use of the catalyst in electrochemostry is also disclosed.
