ORGANIC SILICONE AMINE ELECTROLYTE MATERIAL CONTAINING POLYETHER CHAIN AND USE THEREOF IN ELECTROLYTE SOLUTION FOR LITHIUM CELL

摘要

An organic silicone amine electrolyte material containing polyether chain and the use thereof in electrolyte solution for lithium cell are disclosed. The chemical structure of the organic silicone amine containing polyether chain is shown by formula I, wherein R₁, R₂ are same or different and selected from C1-C10 alkyl; A is polyether chain which is shown by (CH₂)nO[(CH₂)mO]x(CH₂)y, wherein each of n m is an integer of 0-10, x is an integer of 1-10; R₃, R₄ and R₅ are same or different and selected from C1-C10 alkyl or alkoxyl，or are groups equal to ANR₁R₂ or -O-SiR₆R₇R₈, wherein R₆, R₇ and R₈ are C1-C10 alkyl. The electrolyte solution for lithium cell comprises lithium salt, a high dielectric constant solvent or a low boiling-point organic solvent, and the organic silicone amine containing polyether chain which is shown by formula I. The organic silicone amine containing polyether chain also can be used in other electrochemical storage devices and other photoelectric devices as electrolyte material.
