A separator for a rechargeable electrochemical cell that has a conductive first layer and a non-conductive second layer. The non-conductive second layer and the conductive first layer are adhered to one another, wherein the separator has a higher threshold voltage than a threshold voltage of the conductive first layer alone. At a predetermined voltage, the separator becomes conductive and stops further ionic transfers.

Separator for electrochemical cell with overcharge protection and method of making same

An electrochemical device comprises one or more anode, cathode, and separator. In some embodiments, the separator is also an electrolyte. In addition it has two or more current collectors. The anode and cathode are between the two current collectors and each is adhered to an adjacent current collector. The separator is between the anode and cathode and adhered to the anode and cathode. The current collectors are a barrier, and are bonded together to create a sealed container for the anode, cathode, and separator. The electrochemical device may be integrated into a composite panel suitable for uses such as structural load bearing panels or sheets for aircraft wings or fuselage, composite armor, torpedo, missile body, consumer electronics, etc. The electrochemical device may include, but is not limited to, energy storage (batteries, supercapacitors), and energy generation (fuel cells).

Multifunctional cell for structural applications

A separator for a rechargeable electrochemical cell has a conductive first layer and a non-conductive second layer. The non-conductive second layer and the conductive first layer are adhered to one another, wherein the non-conductive second layer has a melting point below a critical temperature for the rechargeable electrochemical cell and discharges the cell when subject to overheating.

Separator for electrochemical cell with thermally induced self-discharge intrinsic in the construction

An electrochemical device includes an electrochemical device having an electrochemical cell located within the sealed first enclosure. The first enclosure has at least a portion that is flexible. A cavity is formed within the first enclosure so that the cavity is in fluidic communication with the electrochemical cell, and pressure inside the sealed first enclosure is less than one half pressure of pressure outside the sealed first enclosure.

Underprinted inlaid sheet materials having unique decorative design

An improved process, particularly adapted for making that type of sheet vinyl covering materials known as inlaids by first depositing resinous particles on a wet ungelled layer of PVC plastisol or organosol and then passing the sheet between a heated, cylindrical surface and a means for gradually and uniformly increasing the contact pressure between the cylindrical surface and the coated surface of the sheet. Upon completion of the step, a substantially uniformly, gelled matrix layer is produced, with the resinous particles embedded therein, and having a smooth and firm surface of uniform thickness.

Process for manufacturing inlaid types of sheet materials

A relatively inexpensive mat is provided which through the application of heat and pressure readily can be densified to form rigid shaped articles. The mat is substantially free of a binder (e.g., a latex binder) and consists essentially of a substantially random array of (a) relatively coarse cellulosic fibers, (b) thermoplastic synthetic polymer fibrils, (c) non-fibrous thermoplastic synthetic polymer particles, and (d) substantially void-free substantially water-insoluble particulate inorganic material (e.g., talc) in the specified quantities. The mat preferably is formed by wet-laying from an aqueous dispersion wherein the (c) and (d) components are dispersed among and physically retained by the (a) and (b) components. A plurality of the mats while stacked may be subjected to heat and pressure to accomplish densification and thermal bonding within and between adjoining sheets to form a laminate. The resulting cellulosic fiber reinforced product can be used to advantage as a shaped rigid panel for use as an inner automobile door liner or in similar end uses which require a rigid sheet or panel having a predetermined configuration. A decorative surface optionally may be applied to the resulting article.

Relatively inexpensive thermoformable mat and rigid laminate formed

A relatively inexpensive mat is provided which through the application of heat and pressure readily can be densified to form rigid shaped articles having a reduced overall density. The mat is substantially free of a binder (e.g., a latex binder) and consists essentially of a substantially radom array of (a) relatively coarse cellulosic fibers, (b) thermoplastic synthetic polymer fibrils, (c) non-fibrous thermoplastic synthetic polymer particles, (d) substantially void-free substantially water-insoluble particulate inorganic material (e.g., talc), and (e) particulate void-containing substantially water-insoluble inorganic material (e.g., expanded volcanic glass) having a lesser density than component (d) in the specified quantities. A plurality of the mats while stacked together with similar mats of greater density on at least the upper and lower surfaces may be subjected to heat and pressure to accomplish densification and thermal bonding within and between adjoining mats to form a laminate. The presence of component (e) in conjunction with the other components has been found to enable the efficient control of the density in the resulting product regardless of the pressure applied during thermoforming. The resulting cellulosic fiber reinforced product can be used to advantage as a shaped rigid lightweight panel for use as an inner automobile door liner or in similar end uses which require a rigid sheet or panel having a predetermined configuration. A decorative surface optionally may be applied to the resulting article.

Relatively inexpensive thermoformable mat of reduced density and rigid

Heat curable liquid polyvinylchloride plastisol or organosol resin is coated onto a porous fiber web in an amount sufficient to saturate the web. Liquid resin on one surface of the web is gelled by passing the web around a heated roll which, together with another heated roll, forms a compression nip. The web passes through the nip and around the second heated roll to gell the resin on the other surface of the web, after which the curing of the resin is completed in an oven.
