Patent ID: 7332247

Claim:
An electrochemical cell, comprising: an open ended container defining a cavity; a first electrode disposed within said cavity; a second electrode disposed within said cavity, said second electrode comprising a mixture of a first set of electrochemically active particles and a second set of electrochemically active particles; a separator forming an ionically permeable and electrically nonconductive barrier between said first electrode and said second electrode; a closure member secured to the open end of said container; wherein the first set of electrochemically active particles comprises zinc and is not agglomerated; wherein the second set of electrochemically active particles comprises a zinc alloy that is chemically distinguishable from the first set of particles; and wherein only one of the first set or the second set of electrochemically active particles is agglomerated through use of an agglomerant, said agglomerated particles comprise less than fifty weight percent of all electrochemically active particles in the second electrode and said agglomerant is at least one selected from the group consisting of: an organic agglomerant, an inorganic agglomerant, polyvinyl alcohol, an alloy of indium and bismuth and an alloy of indium and tin.
