Title (DE) BATTERIEZELLE MIT ISOLATIONSSCHICHT
(EN) BATTERY CELL HAVING AN INSULATION LAYER
(FR) ÉLÉMENT DE BATTERIE DOTÉ D'UNE COUCHE ISOLANTE
Abstract:
(DE) Die Erfindung betrifft eine Batteriezelle (10), insbesondere eine Lithiumionen-Batteriezelle, mit einem Zellgehäuse (1), wobei eine erste elektrische Isolationsschicht (9a) zumindest teilweise auf die Außenfläche des Zellgehäuses (1) aufgebracht ist, welche die Batteriezelle (10) vor Kühlmedien mit einem Widerstand kleiner als 1010 Ω*m, insbesondere einem Wasser-Glykol-Gemisch, abschirmt, sodass die Batteriezelle (10) direkt von dem Kühlmedium, insbesondere dem Wasser-Glykol-Gemisch, direkt umströmt werden kann.
(EN) The invention relates to a battery cell (10), in particular a lithium ion battery cell, comprising a cell housing (1), wherein a first electrical insulation layer (9a) is applied to at least part of the outer surface of the cell housing (1), which first electrical insulation layer shields the battery cell (10) from cooling medium having a resistance of less than 1010 Ω*m, in particular a water-glycol mixture, such that the cooling medium, in particular the water-glycol mixture, can flow directly around the battery cell (10).
(FR) L'invention concerne un élément de batterie (10), notamment un élément de batterie lithium-ion, comprenant un boîtier (1), une première couche électriquement isolante (9a) étant appliquée au moins en partie sur la surface extérieure du boîtier (1) de l'élément de batterie, ladite première couche isolant l'élément de batterie (10) d'agents de refroidissement ayant une résistance inférieure à 1010 Ω*m, notamment un mélange eau-glycol, de sorte que l'élément de batterie (10) peut être parcouru sur son pourtour directement par l'agent de refroidissement, notamment le mélange eau-glycol.
