ZINC-BASED ELECTRODE PARTICLE FORM

摘要

A primary electrochemical cell (10) with an anode (20) 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 (20) can have a low resistivity at low zinc loadings, and the cell (10) can demonstrate good mechanical stability and overall performance.
