Disclosed is a method of joining resin members that includes: forming a coating layer by applying a solvent to a surface of a resin member, the solvent allowing the thermoplastic resin to have a degree of swelling of 1.05 or more and 3.00 or less when the thermoplastic resin is swollen by the solvent, and having a boiling point B° C. of R ° C. or lower where R ° C. is a glass transition temperature of the thermoplastic resin; laminating resin members one another via the coating layer to form a laminate; and pressing the laminate in the lamination direction while heating at a heating temperature H ° C. that is equal to or lower than R ° C.

Method of joining resin members

Disclosed is method of manufacturing a microchannel chip by joining together a resin channel substrate having microchannels formed on at least one side thereof and a resin lid substrate, the method including: a step (A) wherein surface modification treatment is applied on joining surfaces of the channel substrate and the lid substrate; and a step (B) wherein, after the step (A), the joining surfaces of the channel substrate and the lid substrate are mated and the channel substrate and the lid substrate are pressurized under heating via a fluid or an elastic body having a durometer hardness of E20 or less.

Method of manufacturing microchannel chip

A method of manufacturing a lithium-ion secondary battery electrode sheet proposed herein includes the step of pressing granulated particles (), wherein the ratio (t/D50) is less than 1, where D50 is the mean particle size of the granulated particles () and t is the thickness of a layer () of active material particles () after pressing.

Method of manufacturing lithium-ion secondary battery electrode sheet

The double-sided tape for fixing an electrode constituent body is used in an electrochemical device that houses in a pouch-type outer casing an electrode constituent body wherein a positive electrode member, a separator member and a negative electrode member are layered or wound. The double-sided tape comprises a surface having a pressure-sensitive adhesive for adhering to the electrode constituent body, and a surface having a heat-sensitive adhesive for adhering to the pouch-type outer casing.

Method for producing an electrochemical device

A method for manufacturing a lithium ion secondary battery having electrodes in which a mix layer including a first binder and one of a positive electrode active material and a negative electrode active material is formed via a second binder on a collector. The method includes: performing pattern coating of the second binder on the surface of the collector and regularly forming binder-coated sections and uncoated sections; and feeding a powder of mix particles on the binder-coated sections and the uncoated sections so as to form the mix layer on the collector.

Method for manufacturing lithium ion secondary battery

A process for treating the surface of glass fibre to impart resistance to alkalis comprising the steps of (1) immersing glass fibre in an aqueous solution of white muddy composition consisting of water-soluble acrylate resin, styrene acrylate copolymer resin, zirconium oxide, titanium oxide, calcium carbonate, plasticizer and solvent or spraying said aqueous solution over glass fibre and (2) drying the glass fibre.
