摘要： The present invention provides for a zinc-based negative electrode (i.e., anode) for an alkaline electrochemical cell. The negative electrode comprises zinc powder suspended in a gelling agent. The zinc powder has an average particle size substantially greater than 25 micrometers, and preferably has an average particle size of 150 micrometers or smaller. The zinc powder has less than 1 weight percent zinc dust of a particle size less than 25 micrometers. The cell achieves enhanced cell discharge performance at high rate discharge, while minimizing gassing.

摘要： 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.
