FILM-CLAD BATTERY AND METHOD OF PRODUCING FILM-CLAD BATTERY |
| 摘要 |
<p>A joint section where covering films 2a, 2b of film-covered battery 1 are heat-sealed together is formed with flat surface 6' having thickness t 1 and groove 6 having thickness t 2 . Groove 6 serves to reduce the projection area of film-covered battery 1 by folding side 2c toward receiving section 2a1 with groove 6 serving as an edge, and groove 6 is made thinner than flat surface 6' by ”t=t 1 -t 2 . Therefore, the length of covering films 2a, 2b produced on outer side 6a is shortened as compared with the case of folding the portion that has thickness t 1 .</p> |
