    • A nonaqueous electrolyte battery wherein a power generating element formed by spirally winding a positive electrode plate and a negative electrode plate with a separator insulated therebetween, is accommodated in a case. Insulating tapes are adhered to end faces of the power generating element and to portions of side faces of the power generating element in the vicinities of the end faces along the winding direction of the positive electrode plate and the negative electrode plate. With this configuration, the insulating tapes are not deformed at the time when the power generating element is inserted into the case. Hence, it is possible to securely prevent a short circuit between the end faces of the power generating element and the inner faces of the case, and the permeability of the electrolytic solution is improved.
    • 一种非水电解质电池,其中通过螺旋卷绕正极板和负极板与隔膜绝缘的负极板形成的发电元件容纳在壳体中。 绝缘带沿着正极板和负极板的卷绕方向粘附在发电元件的端面和发电元件的侧面的端面附近的端面附近。 通过这种构造,绝缘带在发电元件插入壳体时不变形。 因此,可以可靠地防止发电元件的端面与壳体的内表面之间的短路,并且提高电解液的渗透性。
