Problems solved by technology

[0005] When the temperature rises, the elasticity of the foam saddle decreases, and it is compressed by the pole group in advance, so it cannot support the pole group. After the pole group sinks, the pole group will pull down the battery cover, resulting in increased stress on the battery cover. The battery cover is light. Concave, if heavy, it will crack and leak
[0006] The plastic bracket cannot be deformed. When the pole group grows, the contact point bears all the stress, and the contact point between the pole group and the plastic bracket is prone to positive and negative contact short circuits.

Abstract

The invention provides a lead-acid storage battery mudribs and a preparation method thereof, and a lead-acid storage battery using the mudribs, wherein the mudribs is arranged on the bottom portion of a lead-acid storage battery tank, is positioned below a lead-acid storage battery electrode group, and is a jelly-like solid-state gel. The preparation method comprises: preparing a mixture from silica sol, SiO2 particles having different particle sizes and water, pouring the mixture into the bottom portion of a battery tank, and standing to form the jelly-like solid-state gel. According to the present invention, the solid-state gel can constantly and uniformly support the electrode group within a wide use temperature range, can make space for the electrode group when the battery electrode group performs corrosive growth so as to prevent short circuit, and can further have effects of battery water supplementing, heat out-of-control preventing, and service life prolonging.

Description

technical field [0001] The invention belongs to the field of storage batteries, and relates to a saddle for a lead-acid storage battery and a preparation method. Background technique [0002] Grid corrosion and plate elongation and deformation will occur in the lead-acid battery pole group during use. In order to allow the pole group to have enough room to expand inside the battery, some batteries will place a foam saddle at the bottom to bear the weight of the pole group. When the pole group is stretched, the saddle is compressed. [0003] Another method is to support the battery electrode group in the form of plastic support wire contact, so that the bottom of the electrode group is suspended. When the pole group corrosion elongates, it can grow into the empty space of the plastic support. [0004] However, the main disadvantages of the above technology are: [0005] When the temperature rises, the elasticity of the foam saddle decreases, and it is compressed by the pol...
