(FR) SOLUTION ÉLECTROLYTIQUE POUR CONDENSATEUR ÉLECTROLYTIQUE, ET CONDENSATEUR ÉLECTROLYTIQUE METTANT EN OEUVRE CETTE SOLUTION ÉLECTROLYTIQUE
Abstract:
(EN) The purpose of the present invention is to provide an electrolyte solution for an electrolytic capacitor which has high withstand voltage. The electrolyte solution for an electrolytic capacitor that is used contains: a solvent which contains ³-butyrolactone; an acrylic polymer which has a hydroxy group and/or a carboxy group; and an electrolyte. The acrylic polymer which has a hydroxy group and/or a carboxy group is preferably a polymer which has, as essential constituent monomers, a monomer having (meth)acryloyl group and hydroxy group, and/or a monomer having (meth)acryloyl group and carboxy group.
(FR) L’invention a pour objet de fournir une solution électrolytique pour condensateur électrolytique possédant une tension de tenue élevée. La solution électrolytique pour condensateur électrolytique mise en œuvre dans l’invention comprend : un solvant comprenant un γ-butyrolactone ; un polymère acrylique possédant un groupe hydroxy et/ou un groupe carboxy ; et un électrolyte. De préférence, ledit polymère acrylique possédant un groupe hydroxy et/ou un groupe carboxy a pour monomère constitutif indispensable un monomère possédant un groupe (méth)acryloyle et un groupe hydroxy, et/ou un monomère possédant un groupe (méth)acryloyle et un groupe carboxy.
