An alkaline electrochemical cell has a central cathode having a corresponding cathode current collector electrically connected with a positive terminal of the electrochemical cell. The cathode current collector has a tubular shape, such as a cylindrical shape or rectangular shape, extending parallel with the length of the central cathode. The cathode current collector is embedded within the central cathode, such as at a medial point of a radius of the central cathode, thereby minimizing the distance between the cathode current collector and any portion of the central cathode, thereby increasing the mechanical strength of the cathode and facilitating charge transfer to the cathode current collector.

PRODUCTION METHOD FOR ELECTRODE MEMBER

A method for producing an electrode member that configures an electrode body of an all-solid-state battery, including: a slurry preparation step for preparing a mixed material slurry that contains at least a binder, solid electrolyte particles, and a nonaqueous solvent with low polarity; a molding step for molding the mixed material slurry into a desired shape; and a drying step for obtaining a molded body by removing the nonaqueous solvent with low polarity from the mixed material slurry after the molding. Then, the temperature of the mixed material slurry is controlled so as not to cause re-crystallization of the binder, which has been dissolved in the nonaqueous solvent with low polarity, at least until the initiation of the molding step. Consequently, it is possible to stably provide an all-solid-state battery that has low battery resistance, while improving electrode member production efficiency by preventing gelation of a mixed material slurry.
