摘要： A housing for containing electrode assemblies and an electrolyte includes a cover 18 having a pair of long-side ends 18e. Peripheral thinned portions 11 are formed by cutting the inner face of a top plate 18a near the long-side ends 18e in parallel with the long-side ends 18e. A central thinned portion 15 is formed by cutting the central part of the outer face of the top plate 18a in parallel with the long-side ends 18e. This facilitates the rupture of a housing 1 due to an increase of the inner pressure, while ensuring the strength of the housing 1 to withstand external pressure.

摘要： A separator for alkaline batteries which is obtained by bonding 5.0 to 45.0 g/m2 of a highly hygroscopic macromolecular compound of the crosslinking type having carboxyl group to a wetlaid nonwoven fabric comprising an alkali-resistant fiber, followed by crosslinking the macromolecular compound, wherein a silicate compound is added to the highly hygroscopic macromolecular compound of the crosslinking type in an amount of 1.0×10−4 to 10 mg/cm2 per unit area of the separator. By adding the silicate compound, absorption of the electrolyte is increased, the electrolyte can be held for a long time, the electric resistance of the separator itself can be kept small, growth of dendrite can be suppressed, short circuit due to the formed dendrite can be prevented, the volume of the negative electrode material can be increased by suppressing the thickness of the separator after absorbing the electrolyte, impact of dropping can be endured, and oxidative degradation in the alkaline dry cells can be suppressed. An alkaline primary battery can be constructed using the separator.
