摘要 |
A pocketed electrode plate for use in a ultra-slim lithium ion secondary battery, its manufacturing method and a lithium ion secondary battery using the same. The pocketed electrode plate comprises an electrode plate which has a coating layer of an electrode active material and a non-coated projection portion. The electrode active material can reversibly insert and extract lithium ions. The electrode plates further includes separating membranes which cover both sides of the electrode plate while exposing only the non-coated projection portion, and an insulating polymer having an adhesive component on both surfaces thereof. The insulating polymer film is placed adjacent to edges of the electrode plate but does not cover any portion of the electrode surface. The insulating polymer film is thermally bonded onto two separating membranes. A plurality of pocketed electrode plates may be produced by using a pressing roll. |
