Title (EN) BATTERY CELL HAVING A STRUCTURED ACTIVE MATERIAL
(FR) ÉLÉMENT DE BATTERIE COMPRENANT UNE MATIÈRE ACTIVE STRUCTURÉE
(DE) BATTERIEZELLE MIT STRUKTURIERTEM AKTIVMATERIAL
Abstract:
(EN) The invention relates to a battery cell, in particular a lithium ion battery cell, having a cathode (3), which comprises a cathode active material (333), and having an anode (1), which comprises an anode active material (111), wherein the cathode active material (333) and/or the anode active material (111) is structured in such a way that cavities (4) are located between continuous cathode active material regions (333a) and/or between continuous anode active material regions (111a), which cavities spatially separate the continuous cathode active material regions (333a) and/or the continuous anode active material regions (111a) from each other, and wherein the cavities (4) are at least partly filled with an electrically insulating material (5).
(FR) L'invention concerne un élément de batterie, en particulier un élément de batterie lithium-ion, pourvu d'une cathode (3), comprenant une matière active cathodique (333), et d'une anode (1), comprenant une matière active anodique (111), la matière active cathodique (333) et/ou la matière active anodique (111) étant structurées de telle sorte que des cavités (4) soient présentes entre des zones de matière active cathodique contiguës (333a) et/ou entre des zones de matière active anodique contiguës (111a), lesquelles cavités (4) séparent les zones de matière active cathodique contiguës (333a) et/ou les zones de matière active anodique contiguës (111a) les unes des autres dans l'espace, ces cavités (4) étant au moins partiellement remplies d'une matière électriquement isolante (5).
(DE) Die Erfindung betrifft eine Batteriezelle, insbesondere eine Lithium-Ionen-Batteriezelle, mit einer Kathode (3), umfassend ein Kathoden-Aktivmaterial (333) und mit einer Anode (1), umfassend ein Anoden-Aktivmaterial (111), wobei das Kathoden-Aktivmaterial (333) und/oder das Anoden-Aktivmaterial (111) derart strukturiert ist, dass sich Hohlräume (4) zwischen zusammenhängenden Kathoden-Aktivmaterial-Bereichen (333a) und/oder zwischen zusammenhängenden Anoden-Aktivmaterial-Bereichen (111a) befinden, welche die zusammenhängenden Kathoden-Aktivmaterial-Bereiche (333a) und/oder die zusammenhängenden Anoden-Aktivmaterial-Bereiche (111a) räumlich voneinander trennen, und wobei die Hohlräume (4) zumindest teilweise mit einem elektrisch isolierenden Material (5) aufgefüllt sind.
