A BIPOLAR BATTERY, A METHOD FOR MANUFACTURING A BIPOLAR BATTERY AND A BIPLATE ASSEMBLY

摘要

The present invention relates to a bipolar battery 60 having at least two battery cells comprising: a sealed housing, a negative end terminal 62, a positive end terminal 61, at least one biplate assembly 10, 30, 40 arranged in a sandwich structure between said negative 62 and positive 61 end terminals, and a separator 50, including an electrolyte, arranged between each negative 13 and positive 12 electrode forming a battery cell. The biplate assembly is provided with an inner barrier 14; 22 of a hydrophobic material around the negative 13 and the positive 12 electrode, respectively, and an outer seal around the edge 16 of each biplate. Each end terminal 61, 62 is provided with a terminal seal. The edge 16 of each biplate is positioned close to the sealed housing to provide means to conduct heat from each biplate assembly to the ambient environment. The invention also relates to a method for manufacturing a bipolar battery and a biplate assembly.
