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.
Claims14
A negative electrode for an electrochemical cell, comprising zinc alloy particles suspended in a fluid medium, at least about 6 percent, by weight, of the zinc alloy particles being of −325 mesh size or smaller.
A primary electrochemical cell having
- a cathode,
- an anode comprising zinc alloy particles suspended in a fluid medium, at least 6 percent, by weight, of the zinc-based particles being of −325 mesh size or smaller, and
- a separator between the cathode and the anode.
