Embodiment Construction
[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0022] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention discloses a leak-proof nickel hydrogen battery, which comprises a battery shell component, a battery core and a leak-proof component, wherein the shell component comprises an accommodating shell and a battery hub; the accommodating shell is connected with the battery hub; a convergent zone is arranged at the connection position of the accommodating shell and the battery hub; the battery core is arranged in the accommodating shell and comprises a positive plate, a membrane and a negative plate which are sequentially overlapped together and are wound; the leak-proof component is arranged in the battery hub and comprises a first asphalt sealing and filling ring, a sealing ring, a second asphalt sealing and filling ring and a sealing cover body; the outer side wall of the first asphalt sealing and filling ring is bonded to the inner side wall of the battery hub; the outer side wall of the sealing ring is bonded to the inner side wall of the first asphalt sealing and filling ring; the inner side wall of the sealing ring is bonded to the outer side wall of the second asphalt sealing and filling ring; and the edge of the sealing cover body is bonded to the inner side wall ofthe second asphalt sealing and filling ring. Therefore, the problem of liquid leakage does not easily occur, thereby prolonging the service life and improving the security performance.
Description
technical field [0001] The invention relates to the technical field of nickel-hydrogen batteries, in particular to a leak-proof nickel-hydrogen battery. Background technique [0002] Ni-MH battery is a kind of storage battery with good performance. Ni-MH batteries are divided into high-voltage Ni-MH batteries and low-voltage Ni-MH batteries. Ni-MH battery positive active material is Ni(OH) 2 (called NiO electrode), the negative electrode active material is a metal hydride, also known as a hydrogen storage alloy (the electrode is called a hydrogen storage electrode), and the electrolyte is a 6mol / L potassium hydroxide solution. As an important direction of hydrogen energy application, nickel-metal hydride batteries are attracting more and more attention. [0003] Due to the fact that fossil fuels are less and less in the case of large-scale development and utilization by humans, the development and utilization of hydrogen energy has received increasing attention in recent ...
