Abstract
The invention provides a positive plate for a lead-acid flow battery and relates to the technical field of battery production. A glass transition carbon layer is compressed on the outer surface of a substrate which is formed by mixing and pressing carbon powder and polyethylene. The substrate of the invention is formed by mixing and pressing the carbon powder and high-density polyethylene and is equivalent to a grid of a conventional lead-acid storage battery; and in the positive plate, the glass transition carbon layer is compressed on the substrate to form a positive reaction active layer, and then the surface of the positive plate can be coarsened to increase a surface area. The positive plate can be combined with an appropriate negative plate and electrolyte to form the lead-acid flow battery. The lead-acid flow battery is developed from and extends an all-vanadium flow battery and is mainly characterized in that: only a single type of electrolyte which contains divalent lead ions is needed and is taken as an active substance for an oxidation reduction reaction; the lead-acid flow battery can work by using a liquid storage tank and a pump without a membrane; only a large soluble lead content of the electrolyte is required; and the lead-acid flow battery is formed through a simple dissolving process, which is easy to understand and grasp.
Description
Technical field
The present invention relates to the battery production technical field.
Background technology
It is a kind of large-scale energy storage device that electrochemistry flow battery (Electrochemical flow cell) is commonly referred to redox flow batteries (Redox flow cell).By Charleroi (Thaller) the redox flow batteries notion is proposed the earliest.Last century, the seventies U.S. developed Fe at first
3+/ Fe
2+And full vanadium (V
5+/ V
4+, V
2+/ V
3+) flow battery, in state-owned commercially available prod such as U.S., day, Australia, current China does not have a tame enterprise to stride into this battery industry, does not set foot in the research and development field of this energy storage device so far as yet at present.
The active material of flow battery is liquid, promptly as the electrode reaction active material, hold a concurrent post electrolyte again and do electrode not recurring structure variation at work, can use indefinite duration in theory, the both positive and negative polarity active material separates by the selective permeation film, and redox reaction is carried out on the barrier film both sides respectively, and monocell is made up of bipolar plates (positive pole and negative pole) and barrier film, a plurality of monocells of can connecting are formed the pile of big different model (specification), realize extensive energy storage.Cell voltage is determined by the quantity and the active material classification of Series Sheet battery.Battery capacity is by how many decisions of active material in the fluid reservoir, can 100% deep discharge and harmless substantially to battery, battery can " instant charging " (zero-time) promptly be changed the fluid reservoir of active material or begin to flow and get final product.This class battery life can reach 10 to 20 years, has that reliability height, manufacturing cost, operation and maintenance cost are all lower, a noiselessness, pollution-free, characteristics and advantage such as the construction period is short.Visual angle of conversion can be flow battery as a cycle charge-discharge " fuel cell ".It is not only a consumption chemical energy and transfers the device of electric energy to, but also is an electric energy feedway that the great development space is arranged than " fuel cell ".
The defective that existing redox flow batteries exists is:
1, the barrier film that needs ion selectivity to see through, and lead-acid flow battery is not need barrier film;
2, need the pump of supply positive and negative electrode active material reaction to want two (each one of positive and negative electrode), and lead-acid flow battery is as long as a pump;
3, need two fluid reservoirs to store the required active material of positive and negative electrode respectively, lead-acid flow battery is then as long as a fluid reservoir all is the public lead of both positive and negative polarity.
Summary of the invention
The object of the invention is to design a kind of positive plate that can overcome the lead-acid flow battery of existing redox flow batteries defective.
The present invention is mixing the outer surface of substrate pressing glass transition carbon-coating that compacting forms with polyethylene with carbon dust.
Substrate of the present invention mixes compacting by carbon dust with highdensity polyethylene, the grid that is equivalent to traditional lead acid accumulator, positive plate is pressing one deck glass transition carbon-coating on substrate, forms anodal reactivity layer, then also can with surface coarsening to increase surface area.The present invention and suitable negative plate and electrolyte can be formed a kind of lead-acid flow battery.Lead-acid flow battery is the development and the extension of all-vanadium flow battery, and its main feature is: only a kind of independent electrolyte (the electric liquid that contains lead), and it is the active material that carries out redox reaction, as long as a fluid reservoir, a pump just can carry out work; Do not need barrier film; Only requiring has great amount of soluble lead in the electric liquid, simple course of dissolution just, understandable, easy control.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, form positive plate at the substrate 1 outer surface pressing glass transition carbon-coating 2 that is pressed into by carbon dust and polyethylene mixing.
Claims (1)
1. the positive plate of a lead-acid flow battery is characterized in that: mixing the outer surface of substrate pressing glass transition carbon-coating that compacting forms with polyethylene with carbon dust.
