SECONDARY BATTERY HAVING CASE WITH MULTI ELECTRODE ASSEMBLY-RECEIVING PORTION

摘要

The present invention provides a secondary battery which includes a battery case of a laminate sheet, in which a first and a second electrode assembly which have a structure comprising an anode, a cathode, and a separator formed between the anode and the cathode are embedded. A first receiving part receiving the first electrode assembly and a second receiving part receiving the second electrode assembly are formed in the battery case. The first receiving part and the second receiving part are separated from each other on the battery case. Each outer surface of the first and the second receiving part is fused to form a sealing structure.
