Nanocomposite bipolar storage battery and preparation process of bipolar plate matrix of nanocomposite bipolar storage battery

Abstract

The invention discloses a nanocomposite bipolar storage battery and a preparation process of a bipolar plate matrix of the nanocomposite bipolar storage battery. The nanocomposite bipolar storage battery comprises a matrix, a metal sputtering layer and a nanocomposite bipolar battery, wherein the matrix comprises a thermoset or thermoplastic high-molecular polymer and one or more conductive materials; the conductive materials are uniformly distributed in the matrix; the conductive materials arranged in the matrix are at least one material or a combination of more materials; the particle sizes of the conductive materials are within a nano grade or range from the nano grade to a micro grade; the metal sputtering layer is treated by using a metal vacuum magnetron sputtering technology; the matrix with lead or lead alloy as the sputtering metal is pasted, dried, cured and assembled to obtain the nanocomposite bipolar battery. The nanocomposite bipolar plate prepared by the invention has the advantages of good corrosion resistance, firmness in bonding a polar plate matrix sputtering layer, low contact resistance, light weight, low cost and the like, and can meet the condition for large-scale production.

Description

technical field [0001] The invention relates to a battery, in particular to a nano-composite bipolar storage battery and a preparation process for a bipolar plate base. Background technique [0002] Batteries are divided into primary batteries and secondary batteries, wherein secondary batteries refer to batteries that can be repeatedly charged and discharged. The earliest and most widely used secondary battery is the lead-acid battery, which can be manufactured using unipolar or bipolar, or a quasi-bipolar battery that is used alternately between unipolar and bipolar. [0003] Traditional lead-acid batteries have the following disadvantages: 1. Traditional lead-acid batteries often have acid overflow, acid seepage and gas acid mist escape during use, which not only corrodes equipment, but also pollutes the air, which is extremely harmful to the urban environment; 2. The liquid electrolyte in traditional lead-acid batteries is easy to corrode and wash away the plates, resul...

Problems solved by technology

[0003] Traditional lead-acid batteries have the following disadvantages: 1. Traditional lead-acid batteries often have acid overflow, acid seepage and gas acid mist escape during use, which not only corrodes equipment, but also pollutes the air, which is extremely harmful to the urban environment; 2. The liquid electrolyte in traditional lead-acid batteries is easy to corrode and wash away the plates, resulting in early damage to the plates and the shedding of the active material PbO2 in the plate layer, causing internal short circuits in the batteries and greatly shortening the service life of lead-acid batteries; 3. Traditional lead-acid batteries It is difficult to maintain the battery, and it needs to add acid frequently, adjust the specific gravity, etc., which increases the cost of use; 4. The potential difference between the upper and lower potentials of traditional lead-acid batteries is large, and it is easy to self-discharge; 5. Poor adaptability in harsh atmospheric environments (alpine and high temperature areas), Difficulty starting the vehicle in cold temperatures
