Claims

[Scope of utility model registration request]

(1) Insert a power generation element in which a cathode and an anode are stacked together via a separator into a ring-shaped ceramic, seal the upper and lower openings of the ceramic with a terminal plate, and connect each terminal plate and the ceramic. In a flat battery formed by welding the terminal plate with a brazing material, the thermal expansion coefficient of the terminal plate is less than or equal to the thermal expansion coefficient of the ceramic, and the thermal conductivity of the terminal plate is less than or equal to the thermal conductivity of the ceramic. A flat battery featuring:

(2) Utility model registration In claim (1), the ceramic is made of a dense structure containing 90% or more alumina, while the terminal plate is made of an alloy steel plate of nickel, chromium, and iron, A flat battery characterized in that the coefficient of thermal expansion and thermal conductivity of the terminal plate are approximately equal to the coefficient of thermal expansion and thermal conductivity of the ceramic.
