Recently, JISCO successfully developed 1100G high-performance aluminum foil stock for new energy power batteries, injecting critical new material momentum into the new energy power battery industry. The aluminum foil stock developed in this R&D effort achieved significant optimization in core performance indicators, with outstanding overall performance: its tensile strength reached or exceeded 260 MPa, an improvement of 20 MPa over the previous product; elongation reached or exceeded 4%, an increase of 1 percentage point; double-sided pinhole defects were strictly controlled to within 0.04 per m², nearly achieving the ideal standard of zero pinholes, successfully realizing a leapfrog upgrade in aluminum foil stock performance.
