Abstract: A method for bonding components of a lithium ion battery module includes positioning an energy absorbing insert adjacent to a first thermoplastic layer of the lithium ion battery module and to a second thermoplastic layer of the lithium ion battery module. Energy is applied to the energy absorbing insert to melt the energy absorbing insert and thereby fuse the first thermoplastic layer to the second thermoplastic layer. The first thermoplastic layer is a transmissive or semi-transmissive layer configured to allow the energy the pass through the first thermoplastic layer for absorption by the energy absorbing insert.
