ELECTRICITY STORAGE DEVICE AND METHOD FOR MANUFACTURING ELECTRICITY STORAGE DEVICE

摘要

An electricity storage device which is provided with: an electricity storage element (a cell element (4)) wherein a positive electrode-side electrode body (a collector (120)) and a negative electrode-side electrode body (a collector (140)) face each other with separators (56, 58) being interposed therebetween; a sealing member (a sealing plate (18)) for sealing a case member in which the electricity storage element is contained; one or a plurality of electrode projection parts (a positive electrode part (12) and a negative electrode part (14)) wherein the electrode bodies are led out at an element end face of the electricity storage element; one or a plurality of collector plates (32, 34) which are connected to the electrode projection parts; and terminal members (a positive electrode terminal (28), a negative electrode terminal (30), and connection plates (72, 74)) that are arranged on the sealing member and connected between the collector plates and the lateral surface. Consequently, the electricity storage device has lower resistance and a fast connection structure, while simplifying the connection process.
