| titleOfInvention | ELECTRODE FOR LITHIUM SECONDARY BATTERIES AND METHOD FOR PRODUCING SAME |
| abstract | The object of the present invention is to provide: an electrode for lithium secondary batteries, which has a sufficiently reduced internal resistance, while presenting an excellent security; and a method of producing this electrode for secondary lithium batteries. [1] The invention relates to an electrode for secondary lithium batteries, which is obtained by laminating and integrating a porous polyamide-imide (PAI) layer on the surface of a layer of electrode active material, and which is characterized in that the porous PAI layer has the following characteristics. (1) The ionic conductivity of the porous PAI layer is greater than or equal to 0.6 mS / cm. (2) The thickness of the porous PAI layer is greater than 1 μm but less than 30 μm. [2] The invention relates to a method for producing an electrode for lithium secondary batteries, wherein: a dispersion which contains a binder, fine particles of active material and a solvent is applied to the surface of a metal sheet which serves as a collector of an electrode for secondary lithium batteries, and then the applied dispersion is dried, thereby forming a layer of electrode active material on the metal sheet; and thereafter, a coating liquid which contains a PAI and a solvent is applied to the surface of the electrode active material layer so as to form a coating film, and the phase separation is then caused inside. coating film by removing the solvent from the coating film to form an ion permeable porous layer, while laminating and integrating the electrode active material layer and the ion permeable porous layer. This method of producing an electrode for lithium secondary batteries is characterized in that: the PAI contains, as the diamine component, 4,4'-diaminodiphenyl ether; and the solvent is a mixed solvent which is composed of 5 parts by weight to 20 parts by weight (inclusive) of an amide solvent and 80 parts by weight to 95 parts by weight (inclusive) of tetraglyme (TG) (provided that the total amide solvent and TG is 100 parts by weight). |
