Abstract
A method for making a phase change composite (PCC) for a battery pack of a plurality of electrochemical cells. The method includes impregnating a matrix material with a phase change material, and fragmenting the matrix material before or after the impregnating. The fragmented and impregnated matrix material are shaped into a composite such as by extraction, pressing, or other molding technique. Additional PCC shapes are provided by this invention, such as individual spacers for placement between individual battery cells, or rows of cells.
