Abstract:
A laminate-type battery, comprising:a laminated electrode prepared by laminating a positive plate formed by providing a positive pole active material layer on a surface of a positive pole sheet collector having one edge and another edge, a negative plate formed by providing a negative pole active material layer on a surface of a negative pole sheet collector having one edge and another edge, said one edge of the negative pole sheet collector being located on a side of said one edge of the positive pole sheet collector, and a separator having one edge and another edge and lying between said positive plate and said negative plate, said one edge of the separator being located on said side of said one edge of the positive pole sheet collector, wherein the one edge of the collector of at least one of said positive plate and said negative plate, as a first electrode plate, has a protrusion that protrudes out beyond the one edge of the collector of the other electrode plate, as a second electrode plate, of opposite polarity, and wherein a short-circuit preventing layer for preventing an electrical short-circuit between the first electrode plate and the second electrode plate is provided on or over the protrusion of the first electrode plate.
