Abstract
A negative plate of a lead-acid flow battery relates to the technical field of battery production. A foamed nickel layer is composited on the outer surface of a substrate made of carbon powder and polyethylene by means of mixing and pressing. As the substrate made of the carbon powder and the high-density polyethylene by means of mixing and pressing is equivalent to a grid of a traditional lead-acid storage battery, the negative plate is formed by compositing the foamed nickel layer on the substrate so as to form a negative reactive layer, and the lead-acid flow battery can comprise the negative plate, a proper positive plate and electrolyte. The lead-acid flow battery as development and extension of an all-vanadium flow battery is mainly characterized in that only one individual electrolyte (containing divalent lead irons) is used as an active substance for oxidation-reduction reaction, the lead-acid flow battery is capable of working by the aid of only one liquid storage pot and one water without diaphragms, only a large amount of dissolvable lead, namely a simple dissolving process is needed in the electrolyte, and the lead-acid flow battery is easy to be learned and controlled.
Description
Technical field
The utility model 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.
The utility model content
The utility model purpose is to design a kind of negative plate that can overcome the lead-acid flow battery of existing redox flow batteries defective.
The utility model is mixing the outer surface of substrate composite foam nickel dam that compacting forms with polyethylene with carbon dust.
Substrate of the present utility model mixes compacting by carbon dust with highdensity polyethylene, the grid that is equivalent to traditional lead acid accumulator, negative plate is a composite foam nickel dam on substrate, forms the negative reaction active layer, can form a kind of lead-acid flow battery with suitable positive plate and electrolyte.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 utility model.
Embodiment
As shown in Figure 1, form negative plate at the substrate 1 outer surface composite foam nickel dam 2 that is pressed into by carbon dust and polyethylene mixing.
Claims (1)
1. the negative plate of a lead-acid flow battery is characterized in that: at outer surface of substrate composite foam nickel dam.
