BATTERY PACK

摘要

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 may be molded from a flexible thermoplastic. One of the two spines has 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 thermoplastic resin material. The material may be a mixer 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 one embodiment, the polyolefin is a polypropylene and the aromatic polymer is a poly(phenylene oxide).
