Battery module including a weldless busbar having an integrated fusible link

A battery module includes a plurality of battery cells each configured to store an electric charge and a busbar interconnecting the plurality of battery cells. Each battery cell has a first end surface including a positive terminal, a second end surface, and a perimeter surface including a negative terminal. The busbar has a layered structure including a plurality of parallel-extending layers. The layers include a first conductive layer positioned on the first end surface and contacting each of the positive terminals of the plurality of battery cells, a second conductive layer positioned between the first and second end surfaces and contacting each of the negative terminals of the plurality of battery cells, and at least one isolating layer positioned between the first conductive layer and the second conductive layer. The at least one isolating layers holds the battery cells in position in at least a lateral direction.
