Abstract

The invention provides an anode housing of an alkaline dry cell. The anode housing comprises steel and nickel platings on inner and outer surfaces of the steel. The steel comprises, by weight, 0.01-0.03% of C, less than or equal to 0.02% of Si, 0.18-0.23% of Mn, less than or equal to 0.02% of P, less than or equal to 0.018% of S, 0.005-0.044% of acid-soluble aluminum and the balance Fe. An end part which is in the anode housing close to a cathode of the alkaline dry cell and extends 8-12mm towards an anode of the alkaline dry cell has the thickness of 0.35-0.45mm; and other parts of the anode housing has the thickness greater than or equal to 0.3mm. The invention provides the alkaline dry cell. The alkaline dry cell comprises the anode housing. Through design of raw material composition of the anode housing of the alkaline dry cell, and thickness parameters of the anode housing and the nickel platings, alkaline dry cell safety is improved and explosion after short circuit is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a positive electrode casing for an alkaline dry battery and an alkaline dry battery. Background technique [0002] The positive electrode adopts manganese dioxide, and the negative electrode adopts alkaline dry battery containing alkaline aqueous solution such as zinc and electrolyte. Because of its good performance, low cost and no environmental pollution, it has become a power supply device for various equipment. [0003] The existing alkaline dry battery is usually cylindrical, and the alkaline dry battery is sealed by a battery casing to isolate the internal electrolyte and the like from the external environment. However, when the alkaline dry battery is used abnormally, the chemical substance inside the alkaline dry battery is likely to generate heat and generate a large amount of gas, which increases the internal pressure of the alkaline dry battery and causes the alkalin...
