摘要 |
<p>An alkaline primary battery of the present invention includes a positive electrode containing at least one of manganese dioxide and nickel oxyhydroxide; a negative electrode containing zinc; a separator disposed between the positive electrode and the negative electrode; an alkaline electrolyte; a battery case for housing the positive electrode, the negative electrode, the separator, and the alkaline electrolyte; a sealing plate for sealing the opening portion of the battery case; a resin-made gasket disposed between the battery case and the sealing plate; and a negative electrode current collector inserted in the negative electrode and the gasket. Between the battery case and the gasket, a sealing agent is applied. The sealing agent includes a mixture of a hot-melt resin with a weight average molecular weight of 1000 to 3000 and a softening point of 95 to 160°C; and polybutene with a number average molecular weight of 300 to 700 and a kinematic viscosity at 40°C of 10 to 1000 mm 2 /S.</p> |
