Title:

NEGATIVE ELECTRODE FOR BATTERY AND MANUFACTURE THEREOF

Document Type and Number:

Japanese Patent JPH11345610

Kind Code:

A

Abstract:

To provide a battery with Mg as a negative electrode, having a high energy density and high cycle characteristic.

A negative electrode is used which has fine particles of magnesium or magnesium alloy with average particle size not more than 70 μm. In this case, magnesium amount in the magnesium alloy is preferably not less than 70 wt.%. In manufacturing, fine particles of magnesium or magnesium alloy are produced by a gas atomizing method, a ball mill method or a planetary ball mill method.
