A sealed secondary battery assembly in which electricity-generating elements (1) are accommodated in battery cases (3) formed in rectangular tubular shape having a bottom, a plurality of cells (2a to 2j) constituted by sealing the apertures of battery cases (3) by covers (4) are arranged in series, and these are electrically connected by means of electrical connecting elements (9), wherein the battery cases (3) of the individual cells (2a to 2j) are constituted by a unitary battery case (51) and electrical connection elements (9) are arranged so as to pass through partition sections (53, 54) that define the space for the individual cells (2a to 2j), and coolant passages (55, 56) that communicate with the outside are formed in the partition sections (53, 54).

[ What is claimed is:] [1.]1. A sealed secondary battery assembly, comprising:electricity-generating elements;battery cell cases formed as rectangular tubes having a bottom, opposing partition walls and opposing side walls defining a cell case aperture, said electricity-generating elements being disposed respectively in said battery cell cases;battery cell case covers sealing said cell case apertures to form a plurality of sealed battery cells, said cell case covers being formed contiguous as a unitary cover;said battery cell cases being disposed serially adjacent one another and said partition walls having partition wall surfaces with contacting portions contacting adjacent ones of said partition walls, said contacting portions being fixed together to form a unitary battery case, said partition walls thereby forming partition sections of said unitary battery case which partition said sealed battery cells from one another;electrical connection elements passing through said partition sections, formed by the partition walls, to serially connect said electricity-generating elements without use of electrical connection members extending through said battery cell case covers; andsaid partition walls defining coolant passages in said partition sections.
