Abstract:
In the present invention there is presented a method for the manufacture of lithium batteries utilising solid electrolytes so that the solid electrolyte material is manufactured by pulsed laser ablation deposition and the other material layers either by pulsed laser ablation deposition or some other method applicable for the material in question. In the method, the so-called roll-to-roll method can be used, in which the base material (15, 22, 42, 65, 75, 85, 95) to be coated is directed from one roll (41 a) to the second roll (41 b), and the coating occurs in the area between the rolls (41 a, 41 b). In addition, turning mirrors (31 ) can be used for directing laser pulses (12, 61, 71 a-b, 81 a-d, 91 ) as a pulse front (33) to the surface of the target material (13, 62, 72a-b, 82a-d, 82A-D, 92).

Coatings for components of electrochemical cells (e.g., layers for protecting electrodes) are generally described. Associated compounds, articles, systems, and methods are also generally described.
Abstract:
The present invention pertains to a membrane for an electrochemical device, to a process for manufacturing said membrane and to use of said membrane in a process for manufacturing an electrochemical device.
Abstract:
Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some aspects, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some aspects, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some cases, the protective layer may be porous.
Abstract:
Es wird ein lithiumionenleitendes Verbundmaterial beschrieben, umfassend wenigstens ein Polymer und lithiumionenleitende Partikel, wobei der Grenzflächenwiderstand für die Lithiumionenleitfähigkeit zwischen dem Polymer und den Partikeln aufgrund einer Oberflächenveränderung der Partikel verringert und somit die Lithiumionenleitfähigkeit größer ist als bei einem vergleichbaren Verbundmaterial, bei dem der Grenzflächenwiderstand zwischen dem Polymer und den Partikeln nicht verringert ist.
Abstract:
A microporous membrane or substrate for an electrochemical device having a layer of a metal and/or metal oxide on at least one side of a polymeric porous membrane, wherein said layer is applied using a deposition method or technique such as vapor deposition, and wherein said layer contains one or more phases of a reactive metal oxide.
Abstract:
An insulating (nonconductive) microporous nonwoven polymeric battery separator comprised of a single layer of enmeshed microfibers and nanofibers and supercalendered to extremely thin dimensions and high densities is provided. Such a separator accords the ability to not only attune the porosity and pore size to any desired level through a single nonwoven fabric, but provide further benefits in terms of further reduced pore size, reduced electrolyte level requirements, and reduced total volume of the subject battery cell itself. As a result, the inventive separator permits a high strength material with low porosity and low pore size to levels previously unattained. The separator, a battery including such a separator, the method of manufacturing such a separator, and the method of utilizing such a separator within a battery device, are all encompassed within this invention.
