  • Patent number: 5198162
    Abstract: A microporous polymeric film of high porosity comprises a halopolymer in which the repeating units are --(C.sub.n H.sub.2n)-- and --(C.sub.m X.sub.2m)-- in which each X independently represents fluorine or chlorine and the values of n and m are greater than one and less than six. The film is the result of firstly melt processing a mixture of the halopolymer, more than 150 parts by weight of an extractable salt and not more than 80 parts by weight of an extractable polymer per 100 parts by weight of the halopolymer, the extractable polymer not being completely and homogeneously mixed with the halopolymer and being less viscous than the halopolymer when both are molten so that the surfaces of the film resulting from melt processing are rich in the extractible polymer, and secondly extracting at least some of the extractable salt to render the film porous and extracting at least some of said polymer to impart surface porosity to the film.

  • Patent number: 4892559
    Abstract: Sensitive electrode material, e.g. lithium electrode material, protected by a flexible layer of material which is swellable by liquid with which it will come into contact in use, and can thus, for example, act as an electrode separator when assembled in an electrical cell containing such a liquid. The protected electrode material can be processed, e.g. rolled into thin sheets, and can conveniently be fed to automatic cell assembly apparatus.

  • Patent number: 4882828
    Abstract: Sensitive material, e.g. lithium electrode material, is provided with a protective layer of fluid-impermeable material, which is subsequantly rendered permeable by altering its physical structure, e.g. by perforation, without altering its composition. The permeable material can act, for example, as an electrode separator when the resulting article is assembled into an electrolytic cell, and the protected material can be processed, e.g. rolled into thin sheets, and conveniently fed to automatic assembly apparatus.

  • Patent number: 4849144
    Abstract: A polymeric component, for use as a separator in an electrochemical device in which the anode comprises metallic lithium, comprises a thermoplastic polymer, a tertiary plasticizer and a filler that comprises a lithium compound which is substantially insoluble in both the polymer and the plasticizer. The component is rendered porous by deformation which increases its surface area. The porosity can be enhanced by extracting one or both of the plasticizer and the filler.

  • Patent number: 4675258
    Abstract: A protected electrode article comprising sensitive electrode material having a layer of protective material bonded to at least part of its surface by means of an adhesive which can be made to swell by treatment with liquid, so as to increase the permeability of the adhesive to electrolyte which is encountered by the protected electrode material when incorporated in an electrochemical device.

  • Patent number: 4615961
    Abstract: Continuous metal electrodes are protected by non-porous fluid-impermeable material which is convertible to a fluid-permeable (porous) state, enabling the protective material to act as an electrode separator after the conversion. Conversion by contact with the non-aqueous fluid in a lithium cell is preferred, using strips of lithium protected with a blend of polyethylene and polyethylene oxide, the latter being extractable by the cell liquids.

  • Patent number: 4594299
    Abstract: Electrode material, preferably lithium metal, is protected by a layer of material ready to function as an electrode separator and capable of sufficient ionic conductivity to provide an electrolyte, preferably a solvent-free polymeric electrolyte.

  • Patent number: 4496616
    Abstract: A strip of hollow heat-recoverable articles formed side-by-side by tear welding two lengths of polymeric material together at intervals so that individual articles may be torn off. A preferred method of making the strip involves cross-linking after the tear welding, heating the strip, and inflating the hollow articles to render them heat-recoverable by introducing pressure via an interconnecting passage formed for that purpose during the tear welding.

  • Patent number: 4478252
    Abstract: A device for enclosing elongate objects comprises a dimensionally-recoverable cover which can be wrapped-around the object and closed by means of closure elements located on the cover. The closure elements are preferably in the form of a row of protuberances spaced apart along the edge portions of the cover the protuberances of one edge portion being nestable within the protuberances of the other edge portion. The protuberances are preferably provided with retaining elements which lock the nested protuberances together and will accommodate relative movement between adjacent pairs of nested protuberances to allow the device to be recovered onto objects of varying dimensions.

  • Patent number: 4425174
    Abstract: A process for the production of a heat shrinkable article which comprises forming bonds between regions of at least two superimposed lengths of polymeric material to produce a bonded article so disposed that the desired direction of heat shrinkability lies along the length of the bonded article, cross-linking the bonded article and the bonds between the said lengths of polymeric material, heating the bonded article, stretching the bonded article longitudinally and cooling it (which may comprise allowing it to cool naturally in the stretched condition) to render the articles heat shrinkable. Pneumatic or other methods of expansion may be used in addition to the stretching to render hollow articles heat-shrinkable, the combination of stretching and another such method being advantageous in achieving high expansion ratios while maintaining a reasonable degree of symmetry in the finished hollow recoverable articles.
