Abstract: 1426918 Laminates STANDARD OIL CO 30 April 1973 [9 June 1972] 20425/73 Heading B5N [Also in Division H1] An electronically conducting, ionically insulating current collector or inter-cell connector for a capacitive device (see Division H1) comprises a layer of conductive carbon black loaded elastomer sandwiched between two flexible graphite layers. The graphite layers are each preferably 0À3 tp 10 mils. thick and may have anisotropic conductivity. The elastomer layer may be 2 to 10 mils. thick. The elastomer may be a natural or synthetic rubber, examples of the latter being disclosed, and may include promoters, e.g. nitroso-compounds, to increase its conductivity. The elastomer layer may be applied to one of the graphite layers, optionally as a solution, by calendering, silk screening, spray or brush coating. Alternatively a sheet of the elastomer, prepressed or calendered to desired thickness, is placed between the two graphite sheets. The laminate is consolidated by pressure prior to curing the elastomer by nuclear, ultra-violet or infra-red radiation, steam, hot air or vulcanizing. Comparative examples disclose a single graphite sheet laminated to the loaded elastomer, the latter having a smooth or a roughened surface.

Abstract: 1424894 Impregnated graphite STANDARD OIL CO 30 April 1973 [8 May 1972] 20426/73 Heading C1A [Also in Division H1] An electronically conducting, ionic insulating current collector or inter-cell connector for a capacitive device (see Division H1) comprises flexible graphite sheet impregnated with polymeric material. The graphite may have anisotropic conductively and the impregnant is preferably rendered conductive by loading with carbon black in which case it is preferably an elastomer, e.g. natural or synthetic rubber. Low M.W. impregnants may be applied in fluid form, higher M.W. impregnants as solutions. Non- conductive impregnants may be applied as low M.W. precursors subsequently cured in situ, e.g. butyl rubbers, vinyl nitriles, acrylonitrile and polyacrylonitrile may then be charred in situ. Solutions may be applied by vacuum impregnation, brush or spray coating. Liquid polymer may be painted on to one graphite sheet, covered with a second sheet and the two pressed together to force the polymers into the pores of both. In any case where an elastomer is used, it may be cured by nuclear, ultraviolet or infra-red radiation, steam, hot air or vulcanization.
