ASSEMBLY OF MULTI-CELL CYLINDRICAL BATTERIES ABSTRACT OF THE DISCLOSURE A battery assembly is provided, which comprises a pluralty of generally cylindrical cells of the same type, placed axially in line one with another. The assembly is then wrapped circumferentially with at least one layer of sheet material, usually paper, such that the sheet material covers the assembly along its periphery at least so as to cover the contact regions between each adjacent pair of cells in the assembly. A shrinkable plastic sleeve is then placed over the assembly and is shrunk at least at the ends so that the material at the ends extends radially inwardly at each end of the assembly, but not so as to cover either end. In the preferred embodiment, the sleeve is extruded and heat shrinkable, but it may be spiral-wound or stretchable with elastic memory. File No. PAT2012
