A film to separate 2 electrodes to prevent short-circuiting and retain electrolyte.
A porous or microporous liquid-absorbent material which is installed between the battery electrodes for preventing short-circuit, securing the separation of the electrodes and retaining electrolyte. The separator should be resistant to oxidation and chicals; it should excel in electric insulation and liquid-retention;and it should not disturb diffusion of the electrolyte and ionic conduction
A divider between the positive and negative plates of an element which prevents them from shorting, and allows the flow of current to pass through. They are made from numerous materials such as: polyethylene, polyvinyl chloride, rubber, glass fiber, and cellulose.
An ionically-permeable but electronically non-conductive material installed between the cell anode and cathode. It prevents any electronic contact between them.
A permeable layer that separates and also acts as a release film (e.g., porous Teflon-coated fiberglass). Often placed between lay up and bleeder to facilitate bleeder systems' removal from laminate after cure.
An electronically non-conducting, but ion-permeable, material that prevents electrodes of opposite polarity making contact.
An insulating sheet or other device employed in a storage battery to prevent metallic contact between plates of opposite polarity within a cell.
The barrier in the battery that prevents the negative and positive portions from coming in contact with one another.
An insulator between plates of opposite polarity; usually of wood, rubber or combination of both. Separators are generally corrugated or ribbed to insure proper distance between plates and to avoid too great displacement of electrolyte.
The material separating the electrodes. Used to hold the electrolyte. Normally glass fiber is used.
An ion permeable, electronically nonconductive, spacer or material which prevents electronic contact between electrodes of opposite polarity in the same cell.
A divider made of porous material that is placed in between the positive and negative plates in a battery cell and allows current flow through it while preventing direct contact between the plates which would cause a short circuit.
A device used for the physical separation and electrical isolation of electrodes of opposing polarities.
The permeable membrane that allows the passage of ions, but prevents electrical contact between the anode and the cathode.
An ion permeable, electronically non-conductive material, which prevents electronic contact between electrodes of opposite polarity, within the same cell.
A coating applied to a surface and serving to prevent a second surface from adhering to the first.
A fine coat of material that is applied, usually suspended in some volatile medium, to finished pieces of a multi-piece mold. The material prevents subsequent layers of rubber that form additional mold pieces from bonding with the piece(s) treated by the separator. Some common separators are vaseline desolved in 1.1.1 trichloroethane, workable fixatif, and even hair sprays! Synonymous with intra-mold separator, mold separator, and contaminant layer.
A permeable layer that also acts as a release film. Porous Teflon-coated fiberglass is an example. Often placed between lay-up and bleeder to facilitate bleeder system removal from laminate after cure.
Pertaining to wire and cable, a layer of insulating material such as textile paper, mylar, etc., which is placed between a conductor and its dielectric, between a cable jacket and the components it covers, or between various components of multiple conductor cable. It can be utilized to improve stripped qualities and/or flexibility, or can offer additional mechanical or electrical protection to the components it separates.
A layer of insulating material such as textile, paper, polyester, etc. Used to improve stripping qualities, flexibility, mechanical or electrical protection to the components.
Material for insulation between electrodes of opposite polarity.
