An energy storage apparatus can include a plurality of energy storage sub-modules adjacent one another, each of the plurality of energy storage sub-modules including a plurality of prismatic energy storage devices positioned on a carrying tray. An insulator sleeve can surround the plurality of prismatic energy storage devices positioned on the carrying tray and a pair of side plates positioned around the insulator sleeve. A first of the pair of side plates can be placed adjacent a first side of the insulator sleeve and a second of the pair of side plates can be placed adjacent a second opposing side of the insulator sleeve, where at least one of the pair of side plates has a plurality of protrusions distributed across an exterior surface. An air flow generator can be at a distal end of the energy storage apparatus and configure to draw air into and propel air flow through the energy storage apparatus.
