Problems solved by technology

[0004] The current meson material is PP without surface treatment, and the surface tension is relatively high; when the electrolyte is added, the electrolyte is easy to form a ball on its surface, which is difficult to penetrate; resulting in low efficiency of adding electrolyte, and often the electrolyte is too late Permeation and overflow will affect the quality of the battery

Embodiment 1

[0023] Such as figure 1 As shown, the nickel-hydrogen battery containing novel mesons described in the present invention includes a steel shell 5, and an electric core 6 is arranged inside the steel shell 5. The electric core 6 includes a positive electrode sheet and a negative electrode sheet, and the positive electrode sheet and the negative electrode sheet pass through the guide sheet 2 respectively. Connected with the positive pole and the negative pole, the upper end of the steel shell 5 is covered with a cap 1, and the surface of the battery core 6 is covered with a piece of acidified meson 4 after acidification treatment.

[0024] The preparation method of the described nickel-metal hydride battery comprising the novel meson comprises the following steps:

[0025] 1) Prepare the positive and negative electrode slurry and pull out the positive electrode sheet and the negative electrode sheet. The positive electrode sheet is cleaned by an ultrasonic powder cleaning device...

Abstract

The invention relates to the technical field of nickel-metal hydride batteries, in particular to a nickel-metal hydride battery comprising a novel meson and a preparation method thereof. The nickel-metal hydride battery comprises a steel housing. A battery cell is arranged in the steel housing, a cap covers the upper end of the steel housing, and an acidified meson acidified covers the surface ofthe battery cell. The acidified meson acidified is reduced severely in surface tension and has invasion to an electrolyte. The added electrolyte can penetrate quickly and is absorbed by the battery cell, so that the production efficiency is improved greatly and the battery quality is improved.

Description

technical field [0001] The invention relates to the technical field of nickel-hydrogen batteries, in particular to a nickel-hydrogen battery containing novel mesons and a manufacturing method thereof. 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. The positive active material of the Ni-MH battery is Ni(OH)2 (called NiO electrode), the negative 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. [0003] The surface of the battery cell of the Ni-MH battery needs to be covered with a piece of PP meson. The meson is mainly to prevent the contact between the rolling groove and the battery cell and prevent the battery from short circuiting. [0004] The current meson material is PP without surface ...
