Abstract
Provided herein are prismatic cell assemblies having a continuous cooling channel therethrough. Methods of manufacture of the cell assembly are also provided, wherein each of a series of stacked substantially planar components selected from cathodes, separators, and anodes includes a through hole, and wherein the through holes are concentrically aligned with the adjacent component before securing the assembly using an elongated tube to form a continuous cooling channel through the components. The methods further include inserting the secured stacked components into a pouch having sidewall openings aligned with the continuous cooling channel, and sealing the sidewall openings so that the pouch can be filled with electrolyte without leaking any electrolyte into the cooling channel, or leaking through the pouch sidewall.
