Document Type and Number:
Japanese Patent JP3116643
Kind Code:
B2
Abstract:
PURPOSE:To provide a highly reliable battery for which positioning of positive and negative electrodes becomes unnecessary, whose assembling becomes simple and whose performance failure can be reduced as well as providing a high voltage and large capacity lithium secondary battery. CONSTITUTION:A positive electrode 1 is formed on one surface of a separator 3, and a negative electrode 2 is formed on the other surface, continuously respectively so as to become smaller than separator width, and an electrode - separator integrated material is formed. This is laminated, and a battery is formed. A flexible electrode of a soft binder is adopted, and a material formed by arranging the positive electrode 1 and the negative electrode 2 oppositely to each other through the separator 3 is folded up even number times, and an electrically insulating sealing material 4 is arranged around it, and the superimposed directional both end parts are sandwiched between electrically conductive plate materials 5, and a plate-like battery is constituted and realized. A high voltage and large capacity lithium secondary battery can be provided.
