FLEXIBLE SECONDARY BATTERY

摘要

PURPOSE: A flexible secondary battery prevents the separation between electronic internal components, the relative movement of the electronic internal components, and bending problems. CONSTITUTION: A flexible secondary battery comprises a first electrode layer (10); a first current collector layer (20) which is located on a first electrode layer and has a plurality of through-holes; a separator film (40) which is located on the first current collector layer; a second current collector layer (60) which is located on the separator and has a plurality of through-holes; and a second electrode layer (70) which is located on the second current collector layer. The 180° peeling strength between the first current collector layer and separator or between the second current collector layer and the separator is 1-1000 N/m. The first and second current collector layer is an electroconductive mesh screen or an electroconductive punched film.
