Title: ENERGY STORAGE DEVICE AND METHOD FOR MANUFACTURING ENERGY STORAGE DEVICE
Abstract:
To realize the stabilization of an energy storage device while forming a current collector per se in a compact shape. An energy storage device 10 includes a terminal (negative electrode terminal 300), an electrode assembly 400 having a body portion 430 and tab portions 420 projecting from the body portion 430, and a current collector (negative electrode current collector 150) electrically connecting the terminal and the tab portions 420 with each other. The current collector is configured such that a first plate portion 1521 and a second plate portion 522 which opposedly face each other are continuously formed with each other with a curved portion 1513 interposed therebetween. A thickness t of the curved portion 1513 is set smaller than a thickness t2 of the first plate portion 1521 and a thickness t2 of the second plate portion 1522.
