1. A method of manufacturing a lithium ion battery module, comprising:
- placing a plurality of prismatic battery cells in a battery module housing using a manufacturing system comprising a control system with control logic configured to control an indexing system and a positioning system, wherein the manufacturing system performs an indexing process, wherein the indexing process comprises;
positioning the battery module housing to receive a first prismatic battery cell of the plurality of prismatic battery cells using an actuation mechanism of the indexing system;
placing the first prismatic battery cell into the housing using the placement system;
moving the battery module housing a distance, using the actuation mechanism, to position the battery module to receive a second prismatic battery cell of the plurality of prismatic battery cells, wherein the distance corresponds to an indexed position for each prismatic battery cell of the plurality of prismatic battery cells; and
placing the second prismatic battery cell into the housing using the placement system.

Abstract
Present embodiments include a lithium ion battery module having a lineup of prismatic lithium ion battery cells positioned within a cell receptacle area of a housing of the lithium ion battery module. The prismatic battery cells of the lineup are spaced apart from one another in a spaced arrangement by fixed protrusions extending from internal surfaces of the housing forming the cell receptacle area, and the fixed protrusions extend inwardly to form a plurality of discontinuous slots across a width of the cell receptacle area.
