    Abstract: An apparatus and a method for manufacturing an electricity storage material are provided which can avoid defective coating of the electricity storage material. An apparatus for manufacturing an electricity storage material includes: a dissolving device that dissolves a thickener in a solvent; a viscosity adjusting device that adjusts viscosity of a solution produced by the dissolving device; a first filtering device that filters the solution having the viscosity adjusted by the viscosity adjusting device; and a kneading device that kneads the solution filtered by the first filtering device and an active material. Since the apparatus can remove almost all microgels of the thickener by the first filtering device, defective coating can be prevented in the coating of the electricity storage material, and satisfactory electrodes can be manufactured.

  • Patent number: 9976001
    Abstract: Provided is a process for producing a water-absorbing resin powder which contains a given amount of water added thereto, has a low dust content, and has high material properties. When a water-absorbing resin powder which has undergone surface crosslinking is produced on an industrial scale, various problems concerning production are eliminated and a long-term stable operation is possible without causing a deterioration in the material properties of the resin. Even when the process is continued over a long period, the material properties are stabilized (decrease in standard deviation) or improved (improvement in AAP). The process for producing a water-absorbing resin comprises, in the following order, a first classification step for classifying a water-absorbing resin, a surface crosslinking step after the classification, a water addition step for adding water to the water-absorbing resin powder after or during the surface crosslinking, a second classification step, and a conveying step.
