Secondary battery having a honeycomb sandwich structure for supporting load

摘要

The secondary battery according to the present invention includes an electrode current collector 10 including an upper electrode current collector 11 and a lower electrode current collector 12 disposed on both upper and lower sides; A plurality of support structures 20 disposed between the electrode current collectors 10; An electrode active material 30 applied on the electrode current collector 10; And an electrolyte 40 accommodated on the inner side of the support structure 20 between the electrode current collectors 10, wherein the plurality of support structures 20 continuously includes a plurality of unit cells having a hexagonal shape. It is characterized in that it is a honeycomb-type electrode core structure having a honeycomb configuration arranged as
