Lithium ion battery module with cooling system

A battery module comprising:

• a plurality of carrier assemblies stacked on top of one another to form a cell stack, each carrier assembly comprising:
• a thermally conductive backing plate extending between opposing first and second side edges and opposing top and bottom edges;
• a frame integrally formed with the thermally conductive backing plate and extending from one or more of the first and second side edges and the top and bottom edges, the frame comprising a liquid coolant-receiving channel extending around at least a portion of a perimeter of the backing plate, the perimeter defined by the first and second side edges and the top and bottom edges;
• and
• a battery cell disposed on a front surface of the backing plate, and comprising a compressible foam sheet disposed in front of the battery cell, the battery cell having a positive current collector tab and a negative current collector tab extending from the battery cell, wherein, apart from each endmost current collector tab in the cell stack, each one of the current collector tabs is paired with and connected to a current collector tab of opposite polarity in a battery cell of an adjacent carrier assembly;
• and
• a plurality of compression bars, each compression bar placed over a corresponding pair of connected current collector tabs and adapted to maintain electrical contact between the paired tabs and remove heat therefrom.
