Title:
ELECTROCHEMICAL CELL CONSTRUCTIONS AND METHODS OF MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO2001048836
Kind Code:
A3
Abstract:
A method of making electrochemical cells with high anode-to-cathode interfacial surface area and improved discharge efficiency at high rate discharge, without sacrificing total capacity involves the use of a separator coated electrode (16), and a flowable material comprising a second electrode (12). The first electrode and flowable material comprising the second electrode are disposed in a cell housing (14). The flowable material surrounds the coated surfaces of the first electrode. The invention also provides simplified methods for making electrochemical cells having a high anode-to-cathode interfacial surface area.
