1. A cell assembly, comprising:
a cell frame, bus bars and a thermal plate, the bus bars and the thermal plate being integrated into the cell frame, the cell frame including a top wall and a bottom wall, the bus bars being in-molded into the top wall of the cell frame;
a lithium-ion pouch cell comprising:
a first face;
a second face opposite the first face;
a positive cell terminal; and
a negative cell terminal, the positive cell terminal and the negative cell terminal being arranged at a top end of the pouch cell, the positive cell terminal and the negative cell terminal each being pre-bent substantially at a right angle respective to the first face of the pouch cell; and
a compression element;
the cell frame being configured to receive and house the pouch cell and the compression element in a space defined by the thermal plate and the cell frame;
the thermal plate including a bottom portion which extends through the bottom wall of the cell frame; and
the top wall of the cell frame including geometric features for supporting corresponding placement of the positive cell terminal and the negative cell terminal, the geometric features including a plurality of recesses, the plurality of recesses being shaped to receive the positive cell terminal and the negative cell terminal.
