摘要:
A method of recycling a battery pack (10) that includes an assembled battery composed of a plurality of electric cells that are connected in series to one another includes a heating process of heating the battery pack (10) by supplying a vapor supplied from a vapor boiler (14) into a heat treatment bath (12) for heating the battery pack (10) to replace a space in the heat treatment bath (12) with the vapor, and a condensation process of condensing thermolysis products, which are discharged from the battery pack (10) through the heating process, by a condenser (18).

A method for recycling a battery pack includes steps of: roasting the battery pack that houses a battery assembly that is in a charged condition, as it is, dismantling the roasted battery pack and separating the battery pack into unit cells and parts other than the unit cells, comminuting the unit cells obtained by separation, washing and screening the comminuted cells, dehydrating a slurry below a sieve after screening and recovering metals used for positive and negative electrodes, and recovering metal containing nickel by magnetically separating metal remaining on the sieve after screening, using a magnet.

摘要:
A laminated film of the invention comprises a core layer made of synthetic resin, and a conductive release layer formed on at least one side of the core layer, wherein the conductive release layer comprises condensation reaction type release binder and conductive polymer, and this laminated film of the invention is preferably used as a process film when manufacturing ceramic green sheet by sheet-forming a ceramic material slurry; is able to manufacture a thin ceramic green sheet constantly having an uniform thickness; and is superior in antistatic and release properties.
摘要:
A composite molded article which is produced by joining multilayer boards composed of fiber-reinforced thermoplastic resin onto the surface of a core material made of a foamed resin, and its production method. The composite molded article is constituted by a core material which is composed of a foamed resin molded into a desired shape, and the multilayer boards which are produced such that a plurality of prepregs containing reinforcement fiber by a volume content of not less than 30% and not more than 85% are laminated with the direction of the reinforcement fiber being different with respect to each other, and are heated to not less than a melting temperature of a thermoplastic resin contained therein so as to mutually glue the prepregs, and to remove air contained inside. When the composite molded article is produced, the multilayer boards having been molded into shapes adapted to a shape of the core material are heated to not less than the melting temperature of the thermoplastic resin and are pressed and glued to the core material to make the composite material article.
