NOVELTY - Paste material for use in electrochemical components comprises a heterogeneous mixture of (A) a matrix containing organic polymer(s) or their precursor(s) or prepolymer(s), (B) electrochemically activatable, essentially inorganic liquid which is essentially a non-solvent for (A) and optionally (C) a solid powder which is inert towards (B).    USE - Laminates based on this material are used in primary, secondary or decomposition batteries, preferably with layer thicknesses of 10 microns to 2 mm; layers based on this material are also used in low temperature fuel cells, solar cells or electrochemical sensors, especially sensors for moisture measurement (claimed).    ADVANTAGE - Paste material which already contains conductors (especially electrolytes or at least one electrode) in liquid form, suitable for the production of electrochemically activatable layers in ready-to-use electrochemical components for a wide range of batteries and other products. These components, preferably in the form of film laminates, show very good conductive properties and optionally high flexibility; they cannot run out and therefore eliminate the need for sealed housings.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (a) a self-supporting layer or a layer on a substrate, comprising a heterogeneous mixture of a polymer matrix as in (A), liquid (B) and optionally solid (C); (b) a laminate with electrical properties, comprising (1) a flexible layer containing an organic polymer and a suitable positive electrode material, (2) a layer as in (a), in which the liquid (B) is a substance with electrolyte properties and (3) a flexible layer containing an organic polymer and a negative electrode material; (c) a similar laminate comprising (1) a layer as in (a) in which liquid (B) is a material suitable for use as a cathode or an anode, (2) a flexible layer containing solid electrolytes embedded in an organic polymer matrix and (3) a flexible layer containing liquid or solid electrode material embedded in a polymer matrix, which can act as counter-electrode for layer (1); (d) a process for the production of paste material as above by mixing a crosslinkable prepolymer with components (B) and optionally (C); (e) another process in which (A) is mixed with a plasticizer and optionally powder (C), the plasticizer is leached out with a suitable solvent, the solvent is removed and liquid (B) is then added; (f) a process for the production of layers as in (a) from a paste in which matrix (A) consists of a polymer or prepolymer which is then crosslinked by irradiation (with light or electron beam radiation), heating or immersion in chemical crosslinking agents; (g) another process for the production of layers (a), in which a paste is made from (A), a plasticizer, solvent or swelling agent and optionally (C), the paste is converted into the required layer form, solidified by evaporation of the solvent etc., washed with a solvent to remove the plasticizer and immersed in liquid (B) so as to fill the pores thus formed; (h) a process for the production of laminates as in (b), in which the paste materials for each layer are applied to a substrate, preferably by a compression method, and the layers are then converted into their final compacted state.    DESCRIPTION OF DRAWING(S) - Charge-discharge curve (voltage vs. time) for an electrochemical component with the layer sequence: conducting electrode/spacer tape (thin plastic film)/electrode/electrolyte/electrode/spacer tape/conducting electrode, with LiAlCl4/SO2 as electrolyte.
