  • Patent number: 7604842
    Abstract: Provided are an electrode manufacturing apparatus and a method of manufacturing an electrode in which an electrode capable of preventing the occurrence of an internal short circuit is manufactured. A current collector is passed through a coating position in a downward direction by a reference roll. Thereby, just after coating of a mixture is interrupted, a built-up mixture between the current collector and a coating outlet is pulled in a downward direction by the current collector, so the position of the built-up mixture is lower than the position of the coating outlet. Therefore, the adhesion of the mixture to the coating outlet can be prevented, and as a result, a non-forming region where no mixture is formed can be prevented from being coated with the mixture.

  • Patent number: 7052551
    Abstract: To provide a method of manufacturing a battery capable of providing an equal amount of electrolyte in each battery and of enhancing productivity and coating machines employed thereof. The sensor detects a boundary from the collector exposed region C of the belt-shaped positive electrode to the positive electrode mixture layer exposed region B, on the basis of the detection timing, the shutter is withdrawn to open the flowing path and the proportioning pomp is driven. Following this, when the sensor detected a boundary from the positive electrode mixture layer exposed region B to a collector exposed region C, and on the basis of the detection timing, the shutter is protruded inside the flowing path to close the flowing path and the proportioning pump stops. As a result of this, the electrolyte stops to be delivered from the nozzle. The electrolyte layers are intermittently formed by repeating the same procedures.

  • Publication number: 20050155215
    Abstract: To provide a method of manufacturing a battery capable of enhancing productivity and preventing deterioration of the battery performance. After attaching a positive electrode terminal to a belt-shaped electrode, electrolyte layers are formed. This can decrease the number of manufacturing processes after forming electrolyte layers, which effectively prevents that solvents in the electrolyte evaporates or the electrolyte layers are absorbed the water. Thereby, manufacturing yields of the battery can be enhanced, Additionally, a battery excellent in discharge capabilities and stable in voltage can be attained.
