Embodiment Construction

[0014] Hereinafter, the present invention will be further explained by using the drawings and embodiments.

[0015] Reference Figure 1-3 The zinc-nickel secondary cylindrical alkaline battery cap of the present invention includes a valve core 1, a contact cap 2, a chassis 3 and a connecting piece 4. The surface of the contact cap 2 and the surface of the chassis 3 are both nickel-plated, the valve core 1 is placed in the cavity formed by the chassis 3 with the nickel-plated layer and the contact cap 2 with the nickel-plated layer, and the lower end of the valve core 1 has a nickel-plated layer The gas release hole of the chassis 3 is matched with the gas release hole 5 at the lower part of the contact cap 2. The nickel-plated chassis 3 and the nickel-plated contact cap 2 are spot welded and fixed, and the spot welding points are preferably uniformly distributed Of 3 points. The nickel-plated chassis 3 and the connecting piece 4 are fixedly connected by spot welding, and the sp...

Abstract

A zinc-nickel secondary cylindrical alkaline battery cap, which is characterized in that: the chassis is a stainless steel chassis or a nickel-plated chassis, the surface of the contact cap is plated with a nickel layer, the stainless steel chassis or a nickel-plated chassis and a nickel-plated The contact cap is spot welded and fixed; there is a connecting piece on the lower surface of the stainless steel chassis or the nickel-plated chassis; the stainless steel chassis or the nickel-plated chassis and the connecting piece are strip hot-pressed composites; The connecting piece is spot welded and fixed; the connecting piece is made of copper. Stainless steel or nickel-plated chassis, the nickel-plated contact cap is stable to alkaline electrolytes, there is no quality problem of corrosion and blackening, and the appearance quality and normal performance of the battery can be guaranteed; due to the contact cap with the negative electrode of the battery The connecting piece is made of copper, which has no poisonous effect on the negative electrode and can ensure the excellent performance of the battery. It is suitable for use on a series of zinc-nickel secondary cylindrical alkaline batteries; it has the advantages of reasonable structure, excellent electrical performance, good quality, and long service life. .

Description

Technical field [0001] The invention relates to the technical field of batteries, and is a battery component, more specifically, a zinc-nickel secondary cylindrical alkaline battery cap. Background technique [0002] The original cap used for the zinc-nickel secondary cylindrical alkaline battery is composed of a valve core, a contact cap and a chassis. The chassis is made of steel belts, and the surface is tin-plated. During the life cycle or use of the zinc-nickel secondary cylindrical series alkaline battery with the above cap, when the internal pressure of the battery exceeds the exhaust pressure set by the battery cap, the cap will automatically release the gas in the battery to make the battery internal pressure Restore the normal state to ensure the safety of the battery. But at the same time as the gas is released, the alkaline electrolyte is also taken out of the battery. The alkaline electrolyte will corrode and blacken the metal plating tin on the chassis and also po...
