Abstract:
1. A surface mounting electrochemical device comprising: a container comprising: a first metal component having a recess; and a second metal component welded to the first metal component to close an opening of the recess of the first metal component; a rechargeable electric storage element and electrolyte enclosed in the container; and a first terminal and a second terminal having opposite polarities disposed on a bottom surface for serving as a mounting surface, wherein the electric storage element has a first electrode electrically insulated from the container, and a second electrode electrically conducting with the container, and wherein the first terminal is electrically insulated from the container and electrically conducts with the first electrode of the electric storage element via a relaying element disposed on the container so as to be electrically insulated from the container, and wherein the second terminal electrically conducts with the container and electrically conducts with the second electrode of the electric storage element via the container.
