Method for manufacturing a biplate assembly, a biplate assembly and a bipolar battery
First Claim
1. A biplate assembly in a bipolar battery consisting of:
- a conductive biplate having a first side and a second side opposed to the first side;
a first electrode consisting essentially of a first compressed powder arranged on the first side of the biplate, wherein the first compressed powder comprises a first active material comprising nickel hydroxide and powdered nickel fibers and is not subjected to sintering;
a second electrode consisting essentially of a second compressed powder arranged on the second side of the biplate, wherein the second compressed powder comprises a second active material comprising an AB5 metal hydride and powdered nickel fibers and is not subjected to sintering;
wherein one of the first active material and the second active material is a positive chemically active material and the other of the first active material and the second active material is a negative chemically active material; and
wherein the positive chemically active material and the negative chemically active material chemically react with at least one electrolyte.

Abstract
A biplate assembly may include a biplate, a negative electrode and a positive electrode. A method for manufacturing the biplate assembly may involve selecting the size of the biplate and arranging the positive electrode, which is formed by a compressed first powder, to a first side of the biplate. The first powder contains positive active material. The method may also involve arranging the negative electrode, which is formed by a compressed second powder, to a carrier arranged within the biplate assembly. The second powder contains negative active material. The carrier may be a side opposite to the first side of the biplate. The biplate assembly may be implemented in a bipolar battery.
