Title:
COMBINATION OF ELECTRODES OF PRIMARY BATTERY HAVING SAME ELECTROMOTIVE FORCE AS LEAD ACID BATTERY
Document Type and Number:
Japanese Patent JP2019003919
Kind Code:
A
Abstract:
To provide a primary battery causing the same electromotive force as lead acid batteries and reduced in cost per unit cell, by: increasing the electromotive force of a unit cell so that noise and the like hardly enter portable electrical products such as portable radios to thereby facilitate circuit design; and using, as an electrode, metal which exists more on the earth than zinc as mineral resources and causes a higher electromotive force than zinc by a combination with a carbon rod electrode.SOLUTION: A combination of electrodes of a primary battery that has the substantially same electromotive force as lead acid batteries can be obtained by utilizing difference in ionization tendency of metal. Namely, reference voltages at 25°C of Al and Cu are -1.676 V and +0.337 V, respectively, and the electromotive force of V(Cu)-V(Al) is +2.013 V.SELECTED DRAWING: None
