Definitions

  • Patent Document 1 discloses a power storage device in which a plurality of power storage modules are electrically connected in parallel and a heat dissipation structure is provided on a conductor that electrically connects power storage modules adjacent to each other. In the power storage device described in Patent Document 1, it is possible to efficiently dissipate heat while suppressing an increase in size.
  • the conductor 14 also functions as a heat radiating plate for releasing heat generated in the power storage module 12. Specifically, the conductor 14 has higher thermal conductivity than the contact surface 12 a with the conductor 14 in the power storage module 12.
  • the contact surface 12a of the power storage module 12 with the conductor 14 may be, for example, the electrode plate 34 in the power storage module 12 shown in FIG. It may be a member. That is, the conductor 14 contacts the power storage module 12 directly or indirectly.
  • a through hole 14 a extending in a direction (Y direction) intersecting the stacking direction is provided inside the conductor 14. The through hole 14 a communicates from one side surface facing each other in the conductor 14 to the other side surface.
  • an electrode plate 34 (terminal electrode) having a negative electrode layer 38 disposed on the inner surface is disposed at one end of the laminate 30, and an electrode plate having a positive electrode layer 36 disposed on the inner surface at the other end. 34 (terminal electrode) is disposed.
  • the negative electrode layer 38 of the termination electrode faces the positive electrode layer 36 of the uppermost bipolar electrode 32 through the separator 40.
  • the positive electrode layer 36 of the termination electrode is opposed to the negative electrode layer 38 of the lowermost bipolar electrode 32 with the separator 40 interposed therebetween.
  • the electrode plates 34 of these termination electrodes are connected to the adjacent conductors 14 (see FIG. 1).
  • the separator 40 is formed in a sheet shape, for example.

Abstract

L'invention concerne un dispositif de stockage d'électricité comprenant un module de stockage d'électricité (12) dans lequel une pluralité d'électrodes bipolaires (32), dans chacune desquelles une couche d'électrode positive est disposée sur une surface d'une plaque d'électrode (34) et une couche d'électrode négative est disposée sur l'autre surface de la plaque d'électrode, sont stratifiées dans une direction, des séparateurs (40) étant interposés entre eux. Ce dispositif de stockage d'électricité comprend : un réseau (11) dans lequel des modules de stockage d'électricité sont disposés en réseau dans une direction; et des conducteurs (14), dont chacun est un corps métallique qui est disposé entre des modules de stockage d'électricité adjacents les uns aux autres de façon à être en contact avec les deux modules de stockage d'électricité adjacents. Les modules de stockage d'électricité disposés en réseau dans une direction sont connectés électriquement en série par l'intermédiaire des conducteurs. Les conducteurs ont une conductivité thermique supérieure à celle des modules de stockage d'électricité.
