    摘要： A solid polymer electrolyte is prepared by forming a polymer solution containing a filler into a film, evaporating off the solvent from the film, and impregnating the film with an electrolytic solution. The impregnated polymer electrolyte has a swelling factor of at least 2.2. The method is efficient enough to produce the polymer electrolyte at a low cost. The polymer electrolyte is useful in electrochemical devices such as lithium secondary batteries and electric double layer capacitors.

    摘要： To overcome the drawbacks of a P(VDF-HFP) system gel electrolyte and a cell using the same, a polymer having a vinylidene fluoride copolymer as a backbone and poly-vinylidene fluoride in a side chain featuring good adhesion and exhibiting electro-chemical properties similar to the P(VDF-HFP) system without a crosslinking step is used as a binder for a gel electrolyte or electrode. The invention improves the adhesion of gel electrolyte to a current collector or electrode to reduce internal resistance; develops a polymeric solid electrolyte which is storage stable and capable of continuous lamination of coating layers; and provides an electrode which does not require an extra crosslinking step in assembly procedure, prevents positive and negative electrode materials from stripping off, and experiences a minimal capacitance drop upon repetitive charge/discharge cycles. A lithium secondary cell and an electric double-layer capacitor using the electrode is also described.

    摘要： The present invention provides a manufacturing method for an impeller with which molding and high-quality finishing can be performed extremely easily and quickly through resin molding using a die, and an impeller manufactured by the impeller manufacturing method. A metallic bush is disposed in a die, whereupon a resin material is injected through a gate in the die. A connecting portion between an unnecessary resin portion formed from residual resin material in the gate and a resin impeller main body molded around the bush is formed to be thin, and the unnecessary resin portion is removed from the impeller main body using pushing or withdrawing means.
