Title (EN) ELECTRODE ASSEMBLY AND BATTERY CELL
(FR) ENSEMBLE ÉLECTRODE ET CELLULE DE BATTERIE
Abstract:
(EN) The invention concerns an electrode assembly (10), for a battery cell, containing an anode (11) and a cathode (12) that are divided from one another by means of a separator (18), the anode (11) containing an anode active material layer (21) and an anode current collector layer (23), the cathode (12) containing a cathode active material layer (22) and a cathode current collector layer (24), wherein at least on current collector layer (23, 24) comprises a PTC layer (40) which is interposed between a first conductor layer (41) and a second conductor layer (42). Thereat, the first conductor layer (41) and the second conductor layer (42) are provided in form of segments (51, 52) which are electrically insulated from each other.
(FR) L’invention concerne un ensemble électrode (10), pour une cellule de batterie, contenant une anode (11) et une cathode (12) qui sont séparées l’une de l’autre au moyen d’un séparateur (18), l’anode (11) contenant une couche de matériau actif d’anode (21) et une couche de collecteur de courant d’anode (23), la cathode (12) contenant une couche de matériau actif de cathode (22) et une couche de collecteur de courant de cathode (24), au moins une couche de collecteur de courant (23, 24) comprenant une couche de PTC (40) qui est interposée entre une première couche conductrice (41) et une seconde couche conductrice (42). La première couche conductrice (41) et la seconde couche conductrice (42) sont disposées sous la forme de segments (51, 52) qui sont électriquement isolés l’un de l’autre.
