Abstract
Bipolar battery cells, bipolar batteries, and related methods are disclosed. The disclosed bipolar plate comprises a composite of long carbon fibers and a filler of carbon particles and a fluoroelastomer. A fluoroelastomeric sealant for placement between adjacent cells is also disclosed.
Claims9
A method of making a bipolar cell comprising:
- forming a bipolar substrate from a reinforcement compressed of elongated carbon fibers and a filler comprised of a mixture comprising carbon particles and a fluoroelastomeric material;
- shaping the substrate into a planar form comprising opposed flat surfaces;
- curing the composite into a conductive plate;
- electroplating an electrode at each flat surface.

A method of making a bipolar battery comprising the steps of:
- producing a plurality of bipolar cells each bipolar cell being formed by a method comprising the steps of forming a bipolar substrate from a reinforcement comprised of elongated carbon fibers and a filler comprised of a mixture comprising carbon particles and a fluoroelastomeric material, shaping the substrate into a planar form comprising opposed flat surfaces, curing the composite into a conductive plate, electroplating an electrode at each flat surface;
- placing the bipolar cells in tandem so as to create a reservoir for electrolyte between each adjacent two bipolar cells;
- positioning, curing, and bonding a peripheral seal comprised of cured fluoroelastomeric material imperviously peripherally to and between each adjacent two bipolar plates;
- filling each reservoir with electrolyte.
