Abstract: PROBLEM TO BE SOLVED: To provide a lithium battery by mixing a pigment, a copolymer and a plasticizer in specified ratios, and preparing the melted body of the mixture followed by extrusion molding. SOLUTION: This method comprises preparing the melted body of a mixture containing, in a ratio of 1-100 wt.%, a mixture containing 1-95 wt.% of a pigment containing at least one of an electrochemically inactive solid having a primary grain size of 5 nm-20 μm, a compound capable of releasing Li ion in charging, and a compound capable of receiving Li ion in charging; 5-99 wt.% of at least one copolymer of vinylidene fluoride and 8-25 wt.% of hexafluoroproplylene; and 1-200 wt.%, to the total amount of the pigment and the copolymer, of a plasticizer containing two or more of seven kinds such as dibutyl phthalate, dimethyl phthalate and the like, and subjecting the melted body to extruding process. According to this method, a molded body, particularly, a film-like molded body can be produced.

Abstract: Production of moulded products, especially film includes the following stage (I): compounding and melt-extrusion of a mixture (I) containing 1-100 wt% of a mixture (II) comprising (a) 1-95 wt% pigment(s) (III) with a primary particle size of 5 nm to 20 microns, selected from an electrochemically inert solid (IIIa), a compound (IIIb) which is able to release lithium ions on charging, a compound (IIIc) which is able to take up Li ions on charging, and a mixture of (IIIa) with (IIIb) or (IIIc), (b) 5-99 wt% copolymer(s) (IV) of vinylidene fluoride (VDF) and hexafluoropropylene (HFP) with an HFP content of 8-25 wt% and (c) 1-200 wt% (based on a + b) of a plasticiser (V) selected from dibutyl, dimethyl or diethyl phthalate, tris-(butoxyethyl) phosphate, propylene or ethylene carbonate, trimethyl trimellitate, or a mixture of two or more of these. Also claimed are: (i) a process for the production of composite products comprising (I) forming first layer(s) by compounding and melt-extruding mixture (I) as above, (II) forming second layer(s) by compounding a mixture (I) containing a mixture (II) which contains a solid (IIIa) but not (IIIb) or (IIIc), and then (III) combining these layers by a conventional coating process; (ii) moulded products, especially film, obtained by process stage I; (iii) composite products obtained by the complete process as in (i); (iv) separators, solid electrolytes, electrodes, sensors, electrochromic windows, displays, condensers or ion-conducting film containing moulded products or composites as above; and (v) electrochemical cells containing a separator, solid electrolyte or electrode as in (iv), or a combination of two or more of these.
