Abstract
A primary electrochemical cell with an anode comprising zinc-based particles suspended in a fluid medium is disclosed. The zinc-based particles include at least about 1 percent, by weight, of fines (particles of −200 mesh size) or dust (particles of −325 mesh size). The zinc-based particles can have a relatively small average particle size. The zinc-based particles can be alloyed with, for example, indium and/or bismuth and be of spherical, acicular or flake shape. The anode can have a low resistivity at low zinc loadings, and the cell can demonstrate good mechanical stability and overall performance.
