Abstract
A battery pack is disclosed that includes a battery receiving frame. The frame is a single integral piece comprising two end cap portions and two spine portions, and is preferably molded from a flexible thermoplastic. One of the two spines has a free end, allowing that spine to be flexed so as to create an opening for insertion of electrochemical cells into the frame. The pack optionally includes the application of a label to portions of the frame and cells. The battery pack frame is molded from a thermoplastic resin material. Preferably, the material is a mixture of a polyolefin matrix comprising more than 30 weight percent of the thermoplastic material and an aromatic polymer having a repeating unit that comprises at least one aromatic functional group. In the preferred embodiment, the polyolefin is a polypropylene and the aromatic polymer is a poly(phenylene oxide).
