Abstract
Official abstract text for this publication.
A battery includes an outer package including a laminated film including one or more resin layers, a terminal, and a melt-bonding assisting member including a thermoplastic resin and extending along the terminal. The outer package includes a melt-bonded region at which the terminal is sandwiched between the one or more resin layers. The terminal includes an inner part, a sandwiched part, and an outer part arranged in a first direction. The melt-bonding assisting member internally and externally extends in the first direction beyond contact with the outer package.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery, comprising: an outer package comprising a laminated film comprising one or more resin layers; a terminal; and a melt-bonding assisting member comprising a thermoplastic resin and extending along the terminal, wherein the outer package comprises a melt-bonded region at which the terminal is sandwiched between the one or more resin layers, wherein the terminal comprises an inner part, a sandwiched part, and an outer part arranged in a first direction, and wherein the melt-bonding assisting member internally and externally extends in the first direction beyond contact with the outer package. 2. The battery according to claim 1 , wherein the melt-bonding assisting member externally extends in the first direction beyond contact with the outer package and terminates on the outer part of the terminal. 3. The battery according to claim 1 , wherein the melt-bonding assisting member covers an outer circumference of the terminal. 4. The battery according to claim 1 , wherein, in a second direction perpendicular to the first direction, the melt bonding assisting member covers end surfaces of the terminal. 5. The battery according to claim 4 , wherein, in a sectional view of the melt-bonded region along the second direction, the melt-bonding assisting member forms triangles, bottom sides of which are in contact with the end surfaces, respectively.
