Problems solved by technology

[0003] At present, lead-acid batteries on the market have disadvantages such as low charge formation current efficiency (less than 50%), long internalization time, etc., resulting in waste of electric energy and low production efficiency.
In addition, the long charging time of lead-acid batteries after discharge further limits the development of lead-acid batteries, especially power batteries.

specific Embodiment approach

[0021] This embodiment provides a new type of lead-acid battery. The positive lead paste of the lead-acid battery is added with gold nanoparticles and microgel nanocomposites, and the negative lead paste is added with silver nanoparticles and microgel nanocomposites. The specific implementation is as follows:

[0022] (1) The fabrication process of noble metal nanoparticles and microgel nanocomposites is as follows: figure 1 . in,

[0023] 1. The production method of AuNPs / P(NIPAM-co-DMA) nanocomposite is as follows:

[0024] Using N-isopropylacrylamide (NIPAM) and methacrylic acid-N,N-dimethylaminoethyl ester (DMA) as monomers, P(NIPAM-co-DMA) was obtained by free radical polymerization to prepare a three-dimensional network structure copolymers, and then AuNPs / P(NIPAM-co-DMA) hybrid gels were prepared by an in situ reduction method.

[0025] 2. The preparation method of AgNPs / P(NIPAM-co-DMA) nanocomposite is:

[0026] Using N-isopropylacrylamide (NIPAM) and methacrylic ...

Embodiment 2

[0046] This embodiment provides a new type of lead-acid battery. The positive lead paste of the lead-acid battery is added with gold nanoparticles and microgel nanocomposites, and the negative lead paste does not add any noble metal nanoparticles and microgel nanocomposites, that is The negative electrode is the lead paste of common storage battery. Other implementation processes are the same as in Embodiment 1.

Embodiment 3

Abstract

The invention relates to the field of batteries, in particular to a novel lead-acid storage battery. The novel lead-acid storage battery is prepared from lead paste into which a polymer composite material containing a noble metal is added. According to the novel lead-acid storage battery, unique electric property and good catalytic performance of the noble metal are synthesized, so that the current efficiency can be effectively improved, the container formation time and the charging time in the later use process are greatly shortened and the charging efficiency is improved; and meanwhile, theinternal resistance of the battery is reduced, so that the battery is better in high-rate discharge characteristic and higher in output power.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a novel lead-acid storage battery. Background technique [0002] Lead-acid battery is a kind of battery whose electrolyte is sulfuric acid solution. Its role in low-speed electric tools is mainly: (1) to provide power for vehicles; (2) to provide energy for lighting and other electrical equipment. At present, the country vigorously promotes the promotion of low-speed electric tools, and the concept of consumers has also changed. The electric vehicle market has a bright future. [0003] Lead-acid storage batteries currently on the market have disadvantages such as low charging formation current efficiency (less than 50%), long internalization time, etc., resulting in waste of electric energy and low production efficiency. In addition, the long charging time of lead-acid batteries after discharge also further limits the development of lead-acid batteries, especially power batteries. The ...
