GASKET, BIPOLAR BATTERY AND METHOD OF GASKET MANUFACTURING Russian patent published in 2012 - IPC H01M2/08 H01M10/34 

FIELD: electricity.

SUBSTANCE: gasket (20; 40; 80; 100) contains at least the first packing surface (30; 47; 91; 111) placed as closed loop along frame and projecting from the mentioned top surface (1), and at least the second packing surface (30; 47; 92; 112) placed as closed loop along frame and projecting from the mentioned bottom surface (2), where the mentioned at least the first (30; 47; 91; 111) and the second (30; 47; 92; 112) packing surfaces are made on at least one packing part (26₁, 26₂; 41, 42; 81; 101) made of the second deformable material. At least one of the first and the second materials has hydrophobic properties. The first material of carrying part (27; 44; 82) has higher Young's modulus than the Young's modulus of the mentioned second material of the mentioned at least one packing part (26₁, 26₂; 41, 42; 81; 101).

EFFECT: impermeability, simplicity and lower ohmic losses of bipolar battery, stability of gaskets pack inside it.
