Abstract

PURPOSE:To improve the reaction efficiency of a negative electrode active substance in a cell in the discharge by positioning a synthetic paste fine powder at the inner side bottom of a sealing plate in a reverse conical form. CONSTITUTION:At the inner side bottom of a sealing plate 2 to be a negative electrode, a compound paste material 10 which consists of carboxy- methylcellulose, sodium alginate, sodium polyacrylate, and the like, and gets an adhesive property in the electrolyte is inserted in a reverse conical form, and a mercuric zinc 1 alkaline electrolyte is poured as a negative electrode active substance. An air diffusion paper 8, a water repelling membrane 7, an air electrode 6, and a separator 5 are inserted in a positive electrode case 3, combined with the negative electrode side, and the opening of the case 3 is curled to the inner side. As a result, the negative electrode active substance is concentrated to the separator side, and piled up and solidified to improve the reaction efficiency during the cell discharge.

があった。Problems to be Solved by the Invention In such conventional technology, if the battery is stored as it is after the case 30 curling, the negative electrode active material will separate from the separator due to the difference in specific gravity with the electrolyte. When the deposition capacity is discharged downward with the 5 side facing down, the central part of the negative electrode active material that is solidified due to the reaction from the negative electrode active material that is in contact with the side surface of the sealing plate and the separator surface (section A in Figure 2). )
However, there was a problem in that the reaction efficiency of the negative electrode active material during battery discharge was lower than that of the negative electrode active material near the separator surface or the side surface of the sealing plate.
