Abstract
The invention relates to an electric pile of a redox flow energy storage battery, which is mainly characterized in that on the basis of an electric pile of an existing all vanadium redox flow energy storage battery, only the shape size of a bipolar plate is greater than that of an electrode frame, i.e. the bipolar plate extends out of the electrode frame, the extension direction of the bipolar plate is transverse and/or longitudinal, or the bipolar plate integrally extends towards one lateral surface of the bipolar plate, and one lateral surface of the bipolar plate can also locally extend. Preferably, the edge of the bipolar plate, which extends out of the electrode frame, is connected with a cooling fin. According to the invention, the bipolar plate extends out of the electrode frame to carry out heat exchange with the external environment in a large area, so that the battery is effectively cooled and stable performance and normal work of the battery are guaranteed; and a special heat exchanger is omitted, so that cost of the battery is greatly reduced, and meanwhile, occupation space of the battery is also reduced and the battery is simplified.
Description
Technical field
The present invention relates to a kind of storage battery, particularly liquid flow energy storage battery.
Background technology
Electric energy is difficult to store and is indispensable, and any moment, its production all will be satisfied need for electricity, so people are seeking not only economy but also feasible energy storage technology always, solves the contradiction between the supply and demand, so that the production and need of electric energy breaks off relations.Power storage is at aspect important roles such as electric energy management, electrical network assistant service, voltage control, utilization of regenerative energy, large-scale uninterrupted power supplys in addition, if with the large-scale thermal power associating, can reduce the power station peaking capacity, reduce cost of electricity-generating and reduce and pollute.If with renewable energy power generation associatings such as wind-force, tidal energys, can realize that the continuous and stable of electric energy is supplied with, meet consumers' demand.Because the power that has of flow battery separates with capacity, be easy to design, easy to operate, become gradually one of first-selection of big-and-middle-sized scale electrical power storage.Wherein, all-vanadium liquid flow energy storage battery gains great popularity.This all-vanadium liquid flow energy storage battery capital equipment is pile, the primary structure of this pile is: be provided with amberplex between the positive and negative pole plate (abbreviation bipolar plates) that two are established respectively positive and negative electrode and positive and negative pole plate both sides are respectively equipped with the overall dimension positive and negative electrode frame identical with it, they consist of monocell, monocell both sides arranged side by side are provided with a pair of end plate and collector plate mutually, this a pair of end plate is provided with some through holes corresponding with through hole on the monocell, and each screw rod that passes a pair of end plate and monocell group is positioned at the outer two ends of end plate and establishes clamp nut.
Above-mentioned battery can produce heat when work, battery temperature is raise, and affects its normal operation.People set up heat exchanger in battery for this reason, because electrolyte mostly is strong acid or highly basic, so the requirement of heat exchanger material is very harsh, at present the non-metal kind heat exchangers that adopt more.Its weak point is: thermal transmission coefficient is low, causes heat exchange area large, the huge heaviness of equipment, complex structure.
Summary of the invention
But the object of the present invention is to provide a kind of self heat exchange, and the pile of the high liquid flow energy storage battery of heat exchange efficiency.
The present invention is that pile take existing all-vanadium liquid flow energy storage battery is as the basis, the primary structure of this pile is: be provided with amberplex between the positive and negative pole plate (abbreviation bipolar plates) that two are established respectively positive and negative electrode and positive and negative pole plate both sides are respectively equipped with the positive and negative electrode frame, they consist of monocell, monocell both sides arranged side by side arranged side by side are provided with a pair of end plate and collector plate mutually, this a pair of end plate is provided with some through holes corresponding with through hole on the monocell, and each screw rod that passes a pair of end plate and monocell group is positioned at the outer two ends of end plate and establishes clamp nut.The present invention mainly be the overall dimension of bipolar plates greater than the overall dimension of electrode frame, namely bipolar plates extends to electrode frame outside, contacts with extraneous natural environment large tracts of land, carries out exchange heat.Described bipolar plates extends to the electrode frame outside a lot of modes, and it can be to horizontal and/or longitudinal extension; Can also be that side of bipolar plates is whole extends, and also can be that a side is local extends.Best, the bipolar plates edge that extends to the electrode frame outside links to each other with fin.
The present invention compared with prior art has following advantage:
1, bipolar plates is carried out heat exchange with the external environment large tracts of land outside extending to electrode frame, effectively makes the battery cooling, guarantees that battery performance is stable, works.
2, cancel special heat exchanger, reduced widely the cost of battery, reduce again the occupation of land space of battery simultaneously, battery is oversimplified.
Description of drawings
Fig. 1 is the three-dimensional simplified schematic diagram of pile of the present invention.
Among the figure: 1, end plate (containing collector plate), 2, electrode frame, 3, screw rod, 4, spring, 5, nut, 6, bipolar plates.
Embodiment
In the three-dimensional simplified schematic diagram of the pile of liquid flow energy storage battery shown in Figure 1, just establishing respectively for two, be provided with amberplex and just between the bipolar plates of negative electrode, the negative plate both sides just are respectively equipped with, the negative electrode frame, they consist of 15 monocells, 15 monocell both sides arranged side by side are provided with a pair of end plate and collector plate mutually, this a pair of end plate is provided with some through holes corresponding with through hole on the monocell, each screw rod that passes a pair of end plate and monocell group is positioned at the outer end of end plate and establishes clamp nut, other end cover has preloading spring, establishes clamp nut at the screw rod in the preloading spring outside.Overall dimension 400 * 700 mm of above-mentioned bipolar plates are greater than the overall dimension of electrode frame size 400 * 500 mm, and namely bipolar plates vertically extends up to the electrode frame outside, and the distance at bipolar plates edge and electrode frame edge equals 200mm.
