Ceramic container and battery and electric double layer capacitor using the same

Abstract

A ceramic container includes a ceramic base having a hollow or open portion for accommodating a battery element or an electric double layer capacitor element, defined by a bottom portion and a side wall which surrounds a bottom surface of the bottom portion which bottom face faces the hollow or open portion, a ceramic coating layer formed on a periphery of the bottom face along an inner face of the side wall, a first metallized layer extending, on the bottom face, from a portion provided immediately under the side wall to an inside of an inner end of the ceramic coating layer via a portion provided immediately under the ceramic coating layer, and a conductive layer formed on the bottom face in order to cover an extended portion of the first metallized layer and the ceramic coating layer.

Description

technical field [0001] The present invention relates to ceramic containers used in rechargeable batteries and electric double-layer capacitors, and batteries and electric double-layer capacitors using them. More specifically, it relates to thin batteries and semiconductor memories used in small electronic devices such as mobile phones. Backup batteries for small electronic devices, batteries for backup power supplies of small electronic devices, electric double-layer capacitors, and ceramic containers using them. Background technique [0002] In recent years, portable devices such as mobile phones, portable computers, and video tape recorders with integrated cameras have been remarkably developed, and there is a tendency to pursue further miniaturization and weight reduction. Therefore, along with the simultaneous increase in the demand for batteries as power sources of these portable devices, studies on size reduction and weight reduction by increasing the energy density of...

Problems solved by technology

[0009] However, if the high-performance electrolytic solution B-4 is used for the first metallization layer 12a, there is a problem that the electrolytic solution B-4 is deteriorated due to the dissolution of the components of the first metallization layer 12a in the electrolytic solution B-4. , so that the performance of the battery or electric double-layer capacitor is deteriorated; or the conductivity of the first metallization layer 12a is damaged due to the corrosion of the first metallization layer 12a, and the first metallization layer 12a will be disconnected, etc.
