Title:
高圧型水素化物二次電池
Document Type and Number:
Japanese Patent JP6606041
Kind Code:
B2
Abstract:
A hydride secondary battery includes: a pressure vessel (50); a positive electrode (10) disposed in the pressure vessel (50); a negative electrode (20) disposed in the pressure vessel (50); and hydrogen gas with which the pressure vessel (50) is filled. The negative electrode (20) contains a hydrogen-absorbing alloy. In a pressure-composition-temperature diagram, a desorption curve at 25°C of the hydrogen-absorbing alloy has a plateau pressure of 0.15 MPa or more and 10 MPa or less. The hydrogen gas has a pressure equal to or higher than the plateau pressure at 25°C of the hydrogen-absorbing alloy.
