PURPOSE:To provide a battery having a high capacity whether the discharge is conducted at a high rate or low rate by forming a negative electrode from a mixture powder prepared from globular powder and crushed powder of a hydrogen storage alloy, which are mixed together in a specific proportion. CONSTITUTION:A mixture powder is prepared from globular powder and crushed powder of a hydrogen storage alloy, which are mixed together in a proportion by wt. as 20:80 thru 95:5 and is used as a material to electrode. This gives a high filling density and excellent electron conductiveness. |
