Abstract: This specification teaches a battery structure of lightweight construction. Such a battery is particularly useful as the power source for a space satellite. The battery structure includes a plurality of cells. Each cell has a plurality of non-strengthened cell walls which contact other nonstrengthened cell walls when the cells are in an assembled condition. Each cell also has strengthened cell walls which do not contact any other cell walls when the cells are in an assembled condition. Structurally strengthened end plates are located at opposite ends of the assembled cells to provide support for any nonstrengthened cell walls of the cells coming in contact therewith. Structure is provided for holding the structurally strengthened end plates and cells in an assembled condition. By strengthening only exposed walls, a lightweight battery construction is achieved.

Abstract: A soft paintable polymer composition comprising:(a) from 0 to about 90 parts by weight (pbw) of a hydrogenated block copolymer comprised of at least one vinyl aromatic hydrocarbon and at least one conjugated diene,(b) from about 10 to about 100 pbw of a functionalized hydrogenated block copolymer comprised of at least one vinyl aromatic hydrocarbon and at least one conjugated diene, wherein (a) and (b) must add up to 100 pbw,(c) from about 50 to about 300 pbw of a predominantly aliphatic hydrocarbon processing oil, and(d) from about 5 to about 150 pbw of a polyolefin.
