An electrolyte membrane with a backsheet is sent out from an electrolyte membrane unwinding roller, and is separated with its second side sucked on a suction roller by a first press roller. While the electrolyte membrane from which the backsheet has been separated is transported with the…
Objects of the invention are to provide a solution in which polymer nanofibers are highly dispersed without undergoing gelation and precipitation, its fabrication process, and a polymer nanofiber membrane filter. [0002] Those objects are achievable by use of the nanoparticulate fiber solution in…
The present invention provides a laminated film and a non-aqueous electrolyte secondary battery. The laminated film is a laminated film in which a porous film having a shutdown function, a heat resistant porous layer consisting of an inorganic filler and a binder, and a protective porous layer are…
The present invention provides a process for producing a polymerelectrolyte membrane comprising the steps of coating a solution of a polymerelectrolyte on at least one surface of a porous substrate and laminating the coated porous substrate and a supporting material while applying a tension F…
