Abstract
An electrochemical device comprises a pair of electrodes having electrode layers formed on strip-like collectors except on their strip-like portions along a longitudinal side of the strip-like collectors; strip-like separators insulating these; two collector plates connected to the strip-like portions; a case accommodating these; a lid for sealing the case; a pair of terminals connected to the collector plates and being connectable to an outside of the case. The pair of terminals is respectively connected to the lid and the case, and the pair of electrodes are wound interposing the separators therebetween, and the strip-like portions are located on both end surfaces. The electrochemical device has high volume density and low internal resistance and it can be manufactured in short time.
