  • Method for manufacturing a non-aqueous-gel-electrolyte battery
    Patent number: 6632256
    Abstract: The surface of a positive-electrode active material layer or a negative-electrode an active material layer is coated with a gel electrolyte composition to form a gel electrolyte layer. The positive and negative electrodes are laminated such that the gel electrolyte layer is sandwiched. At this time, the gel electrolyte composition is formed into a sol form so as to be applied to the surface of the positive-electrode active material layer or the negative-electrode active material layer. The viscosity of the gel electrolyte composition formed into the sol form is 1 cp to 50 cp. The gel electrolyte composition is formed into the sol form by heating the gel electrolyte composition or diluting the gel electrolyte composition with nonaqueous solvent. When dilution with the nonaqueous solvent is performed, solvent having a high boiling point and solvent having a low boiling point are mixed with each other.

  • Method of removing particles from a flexible support, and apparatus for practicing same
    Patent number: 4944808
    Abstract: A method and apparatus for removing particles from a flexible sheet. The sheet is run over a rotating rod, rotating oppositely to the moment of the sheet. The rod is immersed on its lower side in a bath of solvent and excess solvent is removed from the bath and is filtered. Additionally, solvent may be applied to the sheet before it reaches the rotating rod or a negative pressure applied just upstream of the rod sucks away the particles.
