Title
(EN) HYDROFLUORIC ACID SCAVENGER
(FR) CAPTEUR D'ACIDE FLUORHYDRIQUE
Abstract
(EN)
The present ivention relates to a non-aqueous electrolyte electrochemical cell such as a double layer capacitor or a battery, which comprises as a hydrofluoric acid scavenging additive a mixture of a salt of oxalic acid and a salt of carbonic acid.
(FR)
L'invention concerne une pile électrochimique électrolytique non aqueuse, telle qu'un condensateur double couche ou une batterie, caractérisée en ce qu'elle comprend un mélange d'un sel oxalique et d'un sel d'acide carbonique comme additif de captage d'acide fluorhydrique.
