Title:
ALUMINUM ELECTROLYTIC CAPACITOR-USE ELECTROLYTIC SOLUTION AND ALUMINUM ELECTROLYTIC CAPACITOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/141620
Kind Code:
A1
Abstract:
The present invention addresses the problem of increasing reliability of an electrolyte capacitor in a manner such that a high initial electric conductivity is maintained without the electrolyte solution leaking even in conditions of further increasing temperature or significant humidity in the surrounding environment. The present invention provides an aluminum electrolytic capacitor-use electrolytic solution which contains a solvent (A) and an electrolyte (D) indicated by general formula (1), wherein the content of at least one type of compound (E) selected from the group consisting of compounds (E1) to (E3) indicated by general formulas (2) to (4), respectively, is less than or equal to 3% by weight with respect to the total weight of ((A) and (D)). [In the formula, (R1) to (R3) are alkyl groups having 1 to 3 carbon atoms, (R4) to (R7) are alkyl groups having 1 to 3 carbon atoms or are hydrogen atoms, and X- is an acid (C) anion.] [In the formula, (R8) is an alkyl group having 1 to 3 carbon atoms. (R9) to (R12) are alkyl groups having 1 to 3 carbon atoms or are hydrogen atoms. In addition, (R11) and (R12) may form a covalent bond.]
