  • Publication number: 20080245735
    Abstract: The present invention relates to flexible ceramic membranes which, depending on embodiment, are useful as separators for batteries, especially lithium batteries, and also a process for their production. Ceramic or hybridic membranes have the disadvantage that, whatever the level of flexibility already achieved, they tend to crumble off the ceramic coating on bending. This is prevented by the present membranes, which comprise, on and in a polymeric nonwoven, a solidified ceramic coating which is constructed from two fractions of metal oxide particles of different size and which adheres to the polymeric nonwoven through a network constructed by two different adhesion promoters.

  • Publication number: 20070099072
    Abstract: The present invention relates to electrical separators for batteries, especially lithium batteries, having a shutdown mechanism and also a process for their production. An electrical separator is a separator which is used in batteries and other arrangements in which electrodes have to be separated from each other while maintaining ion conductivity for example. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a flammable solvent, for example organic carbonates. This is why it is absolutely necessary for a separator for lithium cells to possess a suitable shutdown mechanism and at the same time for it not to be able to melt down. This object is achieved by an electrical separator according to the present invention that comprises a shutdown layer which is formed from a porous sheetlike structure.

  • Publication number: 20060172641
    Abstract: The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.

  • Publication number: 20060166085
    Abstract: The invention relates to separators for lithium batteries and to a process for producing them, and also to their use. The separators of the invention for lithium batteries, based on a sheetlike flexible substrate provided with a plurality of openings and having a porous inorganic electrically insulating coating on and in said substrate, said coating closing the openings in the substrate, the material of the substrate being selected from woven or non-woven electrically nonconductive polymeric fibers and the inorganic electrically conductive coating comprising metal oxide particles, are notable for the fact that the separators have lithium ion conducting properties without the presence of an electrolyte. After filling them with an additional lithium ion conducting electrolyte, the resulting ion conduction is much higher than in the case of conventional combinations of non-lithium ion conducting separators and electrolyte.

  • Publication number: 20060156326
    Abstract: A user profile and/or the suggestions computed based thereon are obtained taking a special set of user features into account. The user features are defined to represent a typical general behaviour of an individual user in respect to the application where the user profile is used. In other words, for each application where a user profile is used a special set of user features are defined which are able to represent a typical general behaviour of an individual user. Based on these user features the weights in the list of word-weight pairs or weighted keywords which represents the user profile are computed or influenced during the creation of the user profile, and/or a multi-user profile is split during the creation of an individual user profile from a multi-user profile, and/or during specification of a suggestion a user history which is used to create the user profile, and/or the user profile, and/or the suggestion results are filtered.

  • Publication number: 20060024569
    Abstract: The present invention relates to electrical separators, especially for use in lithium high energy batteries, and to a process for making them. Separators for use in lithium high energy batteries have to have a very low weight and a very low thickness. It has been found that, surprisingly, such separators having a weight of less than 50 g/m2 and a thickness of less than 35 ?m are preparable by applying a ceramic coating to a polymeric web less than 30 ?m in thickness, these separators being very useful in lithium high energy batteries when pyrogenic oxides of the elements Al, Si and/or Zr are used as a particulate pore-forming component.
