Abstract
In one embodiment, a battery stack assembly includes a plurality of sleeves, a plurality of battery cells, and one or more retention bands. The plurality of sleeves is arranged in a stack along a common plane, each of the plurality of sleeves including a slot. The plurality of battery cells are positioned within the plurality of sleeves such that at least a portion of each battery cell is accessible when positioned within a dedicated sleeve. The one or more retention bands extend through each of the slots formed in the plurality of sleeves, wherein the one or more retention bands facilitate application of compression across the stack, and release of compression allows a chosen cell to be withdrawn from the dedicated sleeve.
