In a prismatic sealed secondary battery according to an embodiment of the present invention, at least one of positive electrode substrate exposed portions and negative electrode substrate exposed portions of an electrode assembly is split into two groups, and therebetween are disposed intermediate members that are made of a resin material and hold one or more connecting conductive members. The two split substrate exposed portions are electrically connected to collector members and to at least one of the connecting conductive members by resistance-welding. Voids are formed in resin material portions of the intermediate members that are located around the resistance-welded portions of the connecting conductive members. Therefore, lowered resistance between the substrate exposed portions and the collector members and stabilized quality of the welds are realized and the manufacturing yield of the prismatic sealed secondary battery is improved.

Also, processes for producing these photovoltaic devices. A plurality of photovoltaic cells having different spectral sensitivity levels are stacked such that at least the photovoltaic cells (2, 4) at the light-incident end and the opposite end have a conductive thin-film layer (5a, 5d) as the outermost layer that undergoes connection, the remaining photovoltaic cell (3) has conductive thin-film layers (5b, 5c) as the outermost layers that undergo connection, and the outermost layers are bonded via anisotropic conductive adhesive layers (6a, 6b) containing conductive microparticles within a transparent insulating material. The conductive microparticles in the anisotropic conductive adhesive layers (6a, 6b) electrically connect the layers in the stacking direction, and the conductive thin film layers (5a, 5b, 5c, 5d) electrically connect the photovoltaic layers (2, 3, 4) that function as bonding materials in the lateral direction (in-plane direction).

The positive electrode substrate exposed portions or the negative electrode substrate exposed portions, or both, of an electrode assembly is split into two groups, and therebetween is disposed an intermediate member made of a resin material and holding one or more connecting conductive members. Collector members for the substrate exposed portions split into two groups is electrically joined by a resistance welding method to the substrate exposed portions split into two groups, together with the connecting conductive member(s) of the intermediate member. The resin material portion of the intermediate member protrudes, in the extension direction of the substrate exposed portions split into two groups, beyond the ends of the substrate exposed portions split into two groups and the ends of the collector member to a prismatic outer can. This structure enables enhanced resistance between the substrate exposed portions and the collector member and curbs variation in the welding strength.

A sealing plate 12 with an electrolyte pour hole 15 is welded to an outer can 11 having a mouth portion. A resin washer 18 is formed on the electrolyte pour hole 15 so as to cover the periphery of the opening of the electrolyte pour hole and the surface of an annular convex portion 17. Next, a nozzle 23 of an electrolyte pouring device 20 is inserted in the electrolyte pour hole 15, and an electrolyte 21 is poured in. Thereafter, an electrolyte 21b adhering to the surface of the resin washer 18 is cleansed or wiped. Then, a blind rivet 16′ is used as a sealing plug 16 to tightly seal the electrolyte pour hole 15. Thus a method for manufacturing a sealed battery in which a peripheral surface of an electrolyte pour hole hardly gets clouded after manufacturing the battery is provided.

A monitoring system of the present invention achieves highly reliable switching control by having a monitored response time creating/calculating unit calculate a maximum value and a minimum value between which a response time is judged as normal from a response time of the last measurement and from a response time of the last but one measurement, and by having a monitored response time comparing unit set a range in which a response time is judged as normal in a manner that agrees with past response times.
摘要:
A prismatic battery is provided with a fixing portion composed of projections 29Aa and 29Ba for fixing the position of a flat electrode assembly 11 and a battery outer can 12 by contacting with an insulating sheet 32 on at least one of a positive electrode collector member 16 and a negative electrode collector member 18. The insulating sheet 32 is provided between the projections 29Aa, 29Ba and the battery outer can 12. Tips 29Ab and 29Bb of the projections 29Aa and 29Ba project from the flat electrode assembly 11 towards the battery outer can 12 side. The height of the projections is smaller than the thickness of the insulating sheet 32. This prevents short-circuiting between the positive electrode collector member or the negative electrode collector member, and the battery outer can. Thus, a prismatic battery suitable for EVs and HEVs with excellent safety can be obtained.
