PILE AYANT UNE MEILLEURE PERFORMANCE D'ISOLATION DE FIL D'ÉLECTRODE ET AYANT UNE EXCELLENTE APTITUDE AU TRAITEMENT DE FABRICATION GRÂCE À UNE STRUCTURE STANDARDISÉE ET BLOC-PILES COMPRENANT LADITE PILE

摘要

A battery cell has a structure in which outer peripheral portions of a battery case are sealed by thermal bonding in a state in which an electrode assembly is mounted together with an electrolyte in a battery case made of a laminate sheet, wherein a pair of electrode leads of the electrode assembly protrude outward from the battery case, and an insulating member is attached to each of the electrode leads in an area of at least 60% of a total area of the electrode leads that protrude outwardly.
