ZINC POWDERS FOR USE IN ELECTROCHEMICAL CELLS

摘要

A zinc powder for use in a zinc anode, negative electrode or electrochemical cell comprising zinc metal or zinc alloy particles. The zinc particles have a narrow particle size distribution and a major portion of the having a well controlled chemistry and specific shape, such as teardrop, strand teardrop, acicular or spherical thereby providing improved discharge characteristics and reduced gassing. The powder can be produced by impulse atomisation.
