<P>PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery capable of restraining an incursion of sputtering inside a power generation element, a vehicle for loading such a lithium ion secondary battery, and a battery loading equipment. <P>SOLUTION: The lithium ion secondary battery 1 includes: the winding type power generation element 10 including a cathode plate 30 having a cathode collector foil 35, a first cathode active material layer 31 and a second cathode active material layer 32, an anode plate 40 having an anode collector foil 45, a first anode active material layer 41 and a second anode active material layer 42, and first and second separators 20, 25, wherein these components are wound about a winding axis AX as a center; a cathode current collector member 71; and an anode current collector member 72. The cathode collector foil includes a first cathode exposure section 37 located at an end in a first width direction DW1, the anode collector foil includes a first anode exposure section 47 located at an end in a second width direction DW2, and the winding type power generation element has at least either of the A and B forms. <P>COPYRIGHT: (C)2011,JPO&INPIT |
