Alkaline electrochemical cell with a blended zinc powder

摘要

A process for producing a blended zinc powder comprising the steps of: segregating a first powder into at least two groups based on particle size; segregating a second powder into at least two groups based on particle size; and blending at least one group from the first powder with at least one group from the second powder thereby forming said blended zinc powder, wherein at least one group from the first powder and one group from the second powder have a common particle size range and the particles in the first powder's common particle size range have an average roughness index value that is at least 2.0 percent higher than the average roughness index value of the particles in the second powder's common particle size range.
