Abstract
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 via the melt-bonding assisting member. The terminal includes an inner part, a sandwiched part, and an outer part arranged in a first direction. The battery has a discharge capacity of 10 Ah or more.
Claims14
A lithium ion battery, comprising:
- an outer package comprising a laminated film comprising one or more resin layers;
- an electrolyte solution held in the outer package;
- a terminal;
- a metal plating layer disposed on the 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 via the melt-bonding assisting member,
- wherein the terminal comprises an inner part, a sandwiched part, and an outer part arranged in a first direction,
- wherein the melt-bonding assisting member internally and externally extends in the first direction beyond contact with the outer package,
- wherein the metal plating layer comprises a single layer,
- wherein the metal plating layer internally and externally extends in the first direction beyond the melt-bonded region, and
- wherein the battery has a discharge capacity of 10 Ah or more.
