Anhydrous organic electrolyte
Abstract
Galvanische Hochenergiezellen mit negativen Leichtmetallelektroden (Li) enthalten als Elektrolytbestandteil häufig Lösungsmittel, darunter Äther, die aufgrund nachbarständiger Gruppen -0-, =CO oder =N- aktivierte C-H-Bindungen aufweisen und zur Bildung explosibler Peroxide neigen. Stabilisator-Zusätze zum Elektrolyten in Mengen von ca. 100 ppm, neben anderen alkylsubstituierten Phenolen namentlich die Substanz 2,6-Di-tert-butyl-4-methyl-phenol oder leicht oxidierbare schwefel- bzw. phosphororganische Verbindungen wie Trimethylphosphit, verhindern diesen Prozeß und machen eine gefahrlose Handhabung der Zellen auch unter ungewöhnlichen Betriebsbedingungen (z.B. lange Überladung bei hohem Strom) möglich.
