WELDING APPARATUS AND A WELDING METHOD FOR SEPARATOR OF ELECTRICAL DEVICE

摘要

An electric device is capable of preventing a heat-resistant material of a separator from scattering even when the electric device vibrates or receives shocks. The electric device has a power generating element formed by alternately laminating a first electrode, a second electrode of a polarity different from the first electrode with a separator interposed therebetween. The separator includes a hot-melt material and the heat-resistant material which is laminated only on one surface of the melt material and having a higher melting point than the melt material. The adjacent separators are welded or joined each other with the heat-resistant material thereof facing each other.

1. An electrical device, comprising:
a power generating element formed by laminating a first electrode, a second electrode of polarity different from the first electrode with a separator interposed therebetween, wherein the separator includes a melt material and a heat-resistant material laminated on only one surface of the melt material and having a melting point higher than the melt material, wherein adjacent separators are joined with the respective heat-resistant material facing each other, and wherein, out of the first electrode and the second electrode, the electrode with a relatively higher frictional force with the heat-resistant material is selected to be sandwiched by the adjacent separators for joining.
