The invention discloses a battery module. The battery module comprises a first current collector assembly, a first carrier layer and a first plurality of battery cells. A first terminal of each of the first plurality of battery cells is electrically coupled to a busbar of the first current collector assembly. A first end of each of the first plurality of battery cells is physically coupled to the first carrier layer. The first carrier layer is positioned between the first current collector assembly and the first plurality of battery cells. The battery module comprises a thermal transfer plate and a first thermal interface material thermally and structurally coupling a second end of each of the first plurality of battery cells to the thermal transfer plate. The first thermal interface material maintains the spatial positioning of the second ends of the first plurality of battery cells on the thermal transfer plate during operation. 本发明公开了一种电池模块。该电池模块包括第一集电器组件、第一承载层和第一多个电池单元。第一多个电池单元中的每个电池单元的第一端子电耦接到第一集电器组件的母线。
