Title:
ALKALINE BATTERY
Document Type and Number:
Japanese Patent JP2023069444
Kind Code:
A
Abstract:
To prevent gas generation and discharge performance reduction when an alloy of zinc and bismuth is used as a negative electrode active material for an alkaline battery.SOLUTION: The alkaline battery has a negative electrode material including a mixed active material of a first zinc alloy powder in which bismuth is alloyed with zinc at a first concentration (e.g., a zinc alloy powder including zinc alloy particles 14a1, 14a2, 14a5, 14a6, 14a7, etc. in Fig. 3) and a second zinc alloy powder in which bismuth is alloyed with zinc at a second concentration higher than the first concentration (e.g., a zinc alloy powder including zinc alloy particles 14a3, 14a4, etc., in Fig. 3).SELECTED DRAWING: Figure 3
