Abstract
An electrochemical cell construction features a novel co-extruded plastic electrode in an interleaved construction with a novel integral separator-spacer. Also featured is a leak and impact resistant construction for preventing the spill of corrosive materials in the event of rupture.
Claims24
A leak and impact resistant construction for a zinc-bromine electrochemical cell, comprising:
- a series of leak-resistant compartments nested within each other, including:
- a first inner compartment for storing a bromine-rich phase;
- a second compartment substantially surrounding said first inner compartment and containing a first electrolyte for circulation through said cell;
- a third compartment substantially surrounding both said second and first compartments and containing a second electrolyte for circulation through said cell;
- and
- an outer casing substantially surrounding said first, second and third compartments.
