Disclosed is a battery structure of a lithium secondary battery comprising an internal electrode body formed by winding a positive electrode, and a negati ve electrode, with a separator sandwiched therebetween, around the outer periphery of a core, and an electrolyte solution to impregnate the internal electrode body, wherein the core is sandwiched to be fixed between caps for sealing the end surfaces of a case f or the battery. Also disclosed is a battery structure of a lithium secondary batter y comprising an internal electrode body formed by winding a positive electrode, and a negative electrode, with a separator sandwiched therebetween, around the outer periphery of a core, and an electrolyte solution to impregnate the internal electrode body, wherein an insulating member is disposed at both ends of the core to extend length of t he core, and the core as well as the insulating member are sandwiched to be fixed between caps to seal end surfaces of a case for the battery. |
