## Abstract

An intercellular support structure of a battery system is provided. The battery system includes cells arranged in an array and a first support structure with a first material to hold a first portion of a first group of cells with a first spacing between the first group of cells. The battery system includes a second support structure, adjacent to the first support structure, which can include a second material to hold, and can provide a second spacing between, a second portion of the first group of cells and a first portion of a second group of cells. The battery system can include a third support structure, adjacent to the second support structure and opposite to the first support structure, which can include the first material to hold a second portion of the second group of cells with the first spacing between the second portion of the second group of cells.
