Title
(EN) ELECTROLYTE ADDITIVE IN PRIMARY BATTERIES FOR MEDICAL DEVICES
(FR) ADDITIF D'ÉLECTROLYTE DANS DES BATTERIES PRIMAIRES POUR DISPOSITIFS MÉDICAUX
Abstract
(EN)
A battery for an implantable medical device (IMD) configured to support a relatively high rate of energy discharge relative to its capacity to support energy intensive therapy delivery, such as high energy anti-tachyarrhythmia shocks, by the IMD. The battery includes a first electrode, a second electrode separated a distance from the first electrode, an electrolyte disposed between the first electrode and the second electrode. The electrolyte includes a lithium salt including LiAsF6, an organic solvent, and an electrolyte additive that includes vinylene carbonate.
(FR)
Une batterie pour un dispositif médical implantable (IMD) est conçue pour supporter un taux relativement élevé de décharge d'énergie par rapport à sa capacité pour supporter une administration de thérapie intensive d'énergie, telle que des chocs anti-tachyarythmie à haute énergie, par l'IMD. La batterie comprend une première électrode, une seconde électrode séparée d'une certaine distance de la première électrode, un électrolyte disposé entre la première électrode et la seconde électrode. L'électrolyte comprend un sel de lithium comprenant du LiAsF6, un solvant organique et un additif d'électrolyte qui comprend du carbonate de vinylène.
