5、 and commercial customers have been hit by the peak use of energy, the price shocks again and again. In order to supply sufficient electricity during peak hours of energy use, larger facilities use high load storage devices to store excess electricity during non peak periods. This makes utilities an

6、d industrial users no longer need to install more power generation facilities for peak power generation and shut down the facilities during off peak hours. High load device allows basic load power generation system in full power, and low efficiency than by carrying device startup, can provide more e

7、fficient energy, because the bearing device start time is long, low efficiency. There are three main load units to choose from, including pump storage, air compression, accumulators, and accumulators. A new type of battery, called F2500, has an energy conversion function that uses zinc bromide to ch

Compared to the conventional lead / acid battery, it has a significantly better cycle (longer life), especially deepThe discharge capacity is better.In this new technology, the storage of bromine allows

9、the system to release as much energy as a fuel cellQuantity. Unlike the full replacement of lead-acid batteries, the zinc bromide battery can be refurbished only if the battery is replaced, and the bromine storage system, pump, and pipe are left intact. The F2500 zinc bromide battery module allows c

10、ustomers to buy energy devices or field power plants at a low cost, reducing energy consumption during peak energy use.F2500 zinc bromide battery inventor: ZBB, Energy, Corporation.

11、es.Project Description: Objective: develop a power module operated by public utilities that provides a flow channel for loading, peaking, and distributing resources for a zinc bromide battery. Zinc bromide battery is a kind of fluid flow battery, includes an electrochemical reactor, the reactor, the

12、 electrolyte from the external tank into the battery slot in the reactor of zinc plate, forming a circulating system. The electrolyte contains bromine in the form of a salt complex and is pumped by the pump.The composite reduces the vapor pressure of bromine and makes storage and system operation sa

13、fer. The energy of the battery can be adjusted by the change of electrolyte. The zinc bromide battery is made of a cost - competitive, high-density polyethylene plastic, which helps reduce production and clean up costs compared to other battery types. In addition, the zinc bromide battery has a curr

14、ent density of 2-3 times that of an acid battery and is lighter in weight. Unlike most other battery systems, the zinc bromide battery does not reduce its service life because of its deep discharge, thanks to the fact that the cathode active ingredient is not degraded and helps to extend the service

15、 life. A zinc bromide cell can be released thousands of times with complete energy. ZBB energy is developing new technologies under the auspices of the office of industrial technology innovation and innovation projects.Progress and milestone: product prototype zinc Detroit Edison circuit test has be

The office of engineering, innovation and innovation from the Ministry of energy also pr

18、ovides technical support for the development of key components of ZBB energy.Economic and commercial potential, using an electric load device for a zinc bromide battery, allows the generator to rely entirely on the basic load generating system rather than the inefficient device that can only be used

19、 for peak power generation. The opening and closing time of the low efficiency generator can be avoided, and the efficiency is improved. In large-scale public utilities, these savings are of great significance. Across the country, millions of barrels of crude oil can be saved by storing energy with

20、a zinc bromide battery. In the United States, and the supply side access because power companies use battery energy economic efficiency is expected in about $57 billion; if the peak, industrial energy consumption based consumption, consume only 1/3, industrial demand will therefore save $13 billion;

21、 especially for renewable energy, long service life and the peak energy demand reduction can save $40 billion 800 million. The model of the F2500 zinc bromide battery has been completed, and Detroit Edison has tested its technical effectiveness. The biggest problem is that the initial cost of the te

22、chnology is high and can only be produced in small quantities. When mass production is feasible, the product will be more popular. But before the scale of business increases, it is necessary to confirm the cost. In the scale of production, the product is considered to be more competitive than lead-a

23、cid batteries in price, and its life is longer, cycle is increased, and it can be recycled almost.2, zinc bromide liquid flow battery technology ZBB zinc energy storage system (ZESS) is a zinc bromide technology and renewable energy storage system based on patent and copyright; the concept and desig

24、n are different from the traditional storage batteries such as lead-acid batteries. Zinc and bromine,The reaction of two common chemicals forms the basis for ZESS technology. The negative electrode of zinc is separated from the positive electrode of bromine by a small porous barrier. Each of them ca

25、n be stored and recycled in the form of zinc bromide aqueous solution. The action of the electrolyte flow with the positive electrode has a balance between bromide storage medium and bromide at an ideal concentration. (Fig. 1) the bromide storage medium is incompatible with the aqueous solution cont

26、aining zinc bromide. All battery components are made of bromide inert plastic. (Figure 2)(Figure 1)(Fig. 2) unlike other batteries such as lead acid batteries, ZESS electrodes do not participate in the reaction process, but only as the substrate for the reaction. Therefore, unlike most rechargeable

27、batteries, they do not produce performance losses due to cyclic wear and tear. During the charging process, the metal zinc in the battery is sputtered from the electrolytic solution to the negative electrode surface. Bromide followed by battery positive electrode surface into bromine, and immediatel

28、y stored in an electrolytic bath in a safe chemical compound in organic phase. When the ZESS is discharged, the metal zinc on the negative electrode is dissolved in the electrolyte and can be recycled for the next sputtering. Under full discharge condition, the ZESS can be placed arbitrarily. The ZE

29、SS, in conjunction with the corresponding size and weight, provides 2 to 3 times the energy density of the existing lead-acid battery (75 to 85 watts / h per kilogram). Its power can also be determined by the choice of customer applications. As a result, ZESSs viability determines the use of its ver

30、satile energy storage.Product design ZESS technology consists of modules, in order to adapt to higher power, you can choose a series of modules. ZESS50 can hold 50KWH, probably a family two days of electricity consumption. There are three batteries, each with 60 batteries. Module volume 4 x 4 x 6.5

31、weighs 3200 pounds. ZESS500 full charge takes 4.5 hours, continuous power generation 250KW, can maintain two hours, with 200% peak shaving capacity. ZESS500 can accommodate ten times the 500KWH and ZESS50, and is often used in commercial or functional areas. The ZESS50 and ZESS500 displays are shown

32、 in Exhibit 4 (figure below).These energy storage facilities can be installed at any place in the ambient temperature, and easy to transport, to meet the needs of renewable energy sources, thereby reducing congestion. The Turnkey feature benefits from the ease of inserting batteries into power grids

33、 or other optional sources. Whats more, the products are mainly made of recycled plastic, which provides the possibility of low cost and economies of scale. The ZESS system maintains a wide range of sources of energy and is highly compatible with the global renewable energy market, such as wind, sol

34、ar, hydro, biofuels, marine power and biomass. ZESS500 also offers a convenient transportation system, weighing about 30000 pounds, and 20 feet of trailers. The modular design aims at increasing or decreasing modules according to the power addition and subtraction, and the prospect is considerable.

35、Other products have no transportation facilities and flexible module design.Zinc bromide battery that zinc battery in each section of bromine in carbon plastic composite electrode in two different electrolytes by polyolefin microporous membrane through in two separate compartmentsWhen discharged, zi

36、nc and bromine are combined to synthesize zinc bromide,Each battery produces 1.8 volts current. This will increase the density of zinc and bromine ions in the two electrolytes. In the process of charging, zinc metal deposition (Du Jin) to form a layer of plastic film composite film electrode side. A

37、t the same time, bromide turns into a film on the other side of the diluted solvent, reacted with other drugs (amines) to form a thick bromine reservoir deposited into the bottom of the electrobath. In the discharge process, it can be dissolved into the remaining electrolyte. The net efficiency of t

The complete zinc bromine zinc storage system is available within a certain size range. Used in applications where unit kinetic energy can reach 1MW/3MWh in removable trailers (stora

39、ge systems, including electricity). These units can be connected in parallel or expanded to larger and larger applications due to the ability to connect in series.
