Lithium secondary battery, secondary battery module, and secondary battery pack

A lithium secondary battery comprising:

• a plurality of wound electrode bodies;
• an electrolyte for infiltrating the wound electrode bodies;
• and
• a battery case housing the wound electrode bodies and the electrolyte;
• wherein each of said plurality of wound electrode bodies comprises:
• a cathode;
• an anode;
• a separator located between the cathode and the anode;
• and
• first and second cathode conducting members, said first cathode conducting member extending from a central portion of the respective wound electrode body, said second cathode conducting member extending from an exterior portion of the respective would electrode body, and said first and second cathode conducting members being connected to each other;
• and
• first and second anode conducting members, said first anode conducting member extending from a central portion of the respective wound electrode body, said second anode conducting member extending from an exterior portion of the respective would electrode body, and said first and second anode conducting members being connected to each other,
• wherein each of said wound electrode bodies has a capacity of 1.5 Ah or less, and
• wherein a cross sectional area of each of said anode conducting members is 0.4 mm2 or less and of each of said cathode conducting members is 0.4 mm2 or less.
