Abstract
The invention relates to a structure of an energy storage battery, in particular an electrode frame structure of a redox flow battery, a mark is made in a specific position of an electrode frame, and the position of an outlet/inlet of the electrode frame and the facing direction of a flow passage groove can be rapidly judged during the assembly process or after the assembly. Therefore, errors during the assembly process can be effectively corrected and the stacking efficiency can be improved. The electrode frame structure is particularly applicable to battery stack structures with the same structure for positive and negative electrode frames or the same shape and the different placement directions.
Description
Technical field
The present invention relates to the structure of energy-storage battery, specifically a kind of electrode frame structure of redox flow batteries.
Background technology
Avoid the threat of climate warming for the mankind, United Nations Framework Convention on Climate Change carries out the index restriction to various countries' greenhouse gas emission, and many for this reason countries progressively tilt the domestically produced energy development strategy to regenerative resource, as wind energy, solar energy, tidal energy etc.Along with wind energy, solar energy, the development of tidal power scale, its generating ratio increases, and the problem that comes out thus is day by day serious.Contradiction between the supply and demand that brings in order to solve the discontinuous sporadic characteristics of renewable energy power generation, the various countries that cause of scale energy storage pay attention to, and its development is imperative.In addition, the scale power storage has irreplaceable effect at aspects such as electric energy management, electrical network assistant service, voltage control, large-scale uninterrupted power supplys, if scale electric energy and large-scale thermal power associating can reduce the power station peaking capacity, reduce cost of electricity-generating and reduce and pollute.Because the power that has of oxidation deoxidization liquid energy-storing battery system separates with capacity, be easy to design, easy to operate, become one of first-selection of the most promising scale electrical power storage gradually.Wherein, vanadium redox battery enjoys favor.
Liquid flow energy storage battery (heap) be redox flow batteries energy-storage system core component, critical piece such as Fig. 2: end plate is arranged, collector plate, electrode frame, electrode, bipolar plates, amberplex and seal etc.At the maximum seal of quantity, in electrode and the electrode frame, electrode frame is the easiest assembling parts of makeing mistakes, and misplaces the performance that direction gently then influences pile, and is heavy then serious consequences such as antipole occur.Special positive and negative electrode frame profile is the same or similar, in the pile assembling process or after the assembling, the judgement of electrode frame placement direction is difficult unusually, by each electrode frame placement direction under the very difficult well-documented history of assembling record.The electrode frame placement direction often to occur unclear for this reason, and the phenomenon of refitting has a strong impact on assembling efficiency.
Summary of the invention
Have problems in order to solve on the above-mentioned flow battery structure, particularly in the assembling process or the problem of assembling rear electrode frame placement direction difficult judgment.The present invention proposes a kind of electrode frame structure of redox flow batteries, and it is simple and reasonable, is easy to identification.
For achieving the above object, the technical solution used in the present invention is:
A kind of electrode frame structure of redox flow batteries, the sidewall of the electrode frame of battery or pile is provided with sign, can be in assembling process or assembling after, judge the going out of electrode frame/entry position and flow path groove towards.
The described specific markers that is designated groove, hole, projection, cut or has the pigment application of particular color.
Be meant on the sidewall of described electrode frame electrode frame can observed electrode frame after being assembled into battery or pile on the position, particularly on the outer surface of electrode frame.
Being distributed with common conduit, electrolyte on the described electrode frame goes out/general functional structure such as entrance channel, fluid distributor, sealing wire casing and/or location hole.
As: the ad-hoc location in electrode frame is made sign, can be in assembling process or assembling after, judge rapidly the going out of electrode frame/entry position and flow path groove towards.Can effectively correct the assembling process mistake like this, improve dress heap efficient.It is identical or profile is identical, the electric pile structure that placement direction is different that the present invention is specially adapted to the positive and negative electrode frame.
The invention has the advantages that:
1 is simple and reasonable, is easy to identification.
2 fringe costs are low, are easy to batch machining.
Description of drawings
Fig. 1 is electrode of liquid flow cell frame of the present invention and sign thereof; 1 electrolyte outlet, the sign of 2 electrode frame, 3 flow path grooves, 4 electrolyte entrances;
Fig. 2 is flow battery assembling pile figure of the present invention; 5 end plates, 6 electrode frame.
Embodiment
Electrode frame structure as shown in Figure 1, the sign of electrode frame is to contain on the face of runner one side in electrode frame, and on the long limit at electrolyte outlet place, processes a 5mm half slot, degree of depth 2mm.In assembling process (as Fig. 2) for this reason, from the position of the groove of electrode frame, and towards the laying state that can judge electrode frame.
Electrode area: 225cm wherein
2, monocell number: 15.
Claims (5)
1. the electrode frame structure of a redox flow batteries, it is characterized in that: the sidewall of the electrode frame of battery or pile is provided with sign.
