Abstract
An electrode containing zinc-based particles suspended in a fluid medium is disclosed. The zinc-based particles have a multi-modal distribution, such as a bi-modal distribution, of particle sizes, particle morphologies and/or particle compositions. The electrode can be used as the anode in an alkaline battery, such as a primary alkaline battery.
Claims8
An electrochemical cell having
- a cathode;
- an anode comprising zinc alloy particles suspended in a liquid medium, the particles being suspended in a fluid medium, at least 10% by weight, of the particles being of −200 mesh size or smaller, the particles having an effective particle size diameter distribution with a largest peak between 50 microns and 100 microns;
- a separator;
- and
- an alkaline electrolyte.
