摘要:
The present invention provides an enclosed lead storage battery comprising a plate assembly consisting of a positive plate (a), negative plates (11) and a separator (10), an electrolyte held in position by the plate assembly, and a Jacket (12) made of film- or sheet-formed synthetic resin and surrounding the plate assembly and electrolyte. The jacket is of a multilayer laminate structure made by disposing a polyolefin film on the inside contacting the plate assembly and laminating a film of thermoplastic synthetic resin in two or more layers of the outside thereof. According to the present invention, the plate assemby can be encased with an unexpensive jacket of a simple construction, and the joint of the jacket to the pole posts of the plate assembly is strengthened to offer a leak-proof enclosed lead storage battery.
