Abstract
A battery module and methods for bonding a cell terminal of a battery to an interconnect member are provided. The battery module includes a battery cell having a cell terminal, and an exothermal reactive layer having first and second sides. The first side is disposed adjacent to the cell terminal. The module further includes an interconnect member disposed adjacent to the second side of the exothermal reactive layer. The exothermal reactive layer is ignited to form a bonding joint between the interconnect member and the cell terminal in response to a laser beam contacting at least a portion of the exothermal reactive layer.
Claims20
A battery module, comprising:
- a battery cell having a cell terminal;
- an exothermal reactive layer having first and second sides, the first side being disposed adjacent to the cell terminal;
- and
- an interconnect member disposed adjacent to the second side of the exothermal reactive layer, the exothermal reactive layer is configured to ignite to form a bonding joint between the interconnect member and the cell terminal in response to a laser beam contacting at least a portion of the exothermal reactive layer.
A method for bonding a cell terminal of a battery to an interconnect member, comprising:
- disposing an exothermal reactive layer between the interconnect member and the cell terminal of the battery cell, utilizing a component placement machine;
- and
- emitting a laser beam from a laser for a predetermined amount of time that contacts at least a portion of the exothermal reactive layer and ignites the exothermal reactive layer to form a bonding joint between the interconnect member and the cell terminal.
A method for bonding a cell terminal of a battery to an interconnect member, comprising:
- disposing the interconnect member having an exothermal reactive layer previously disposed thereon adjacent to the cell terminal utilizing a component placement machine;
- emitting a laser beam from a laser for a predetermined amount of time that contacts at least a portion of the exothermal reactive layer and ignites the exothermal reactive layer to form a bonding joint between the interconnect member and the cell terminal.
