About the benefits and features of working with lead-acid technologies today said the Dean of power faculty of BNTU, doctor of physico-mathematical Sciences, Professor Kirill Viktorovich Dobrego.
Today, the industry energy storage is unique in terms of growth and technological perspectives that are associated with it. According to experts, in recent years, the growth rate of the market energy storage ~27% per year and this trend continues.
Technological perspective the development of energy storage is, above all, the cheapening of electric power for consumers by leveling the load on the network, creating the optimal conditions for generating capacity. The latter factor will become particularly important after the start of the Belarusian nuclear power plant.
The fundamental is that there is enough cheap storage of electricity is the key to the wide application of renewable and environmentally clean sources of solar energy and wind energy. Estimated we can say that for the development of 10 kW. hours of power per day from renewable sources of energy need to install a battery capacity of about 5 kW. h (7 car batteries). The availability of cheap energy storage needed to reduce the cost of many services — communications, transport, security, etc.
The term "cheap storage" is invested not only his one-time purchase price, but the cost of restoration and replacement of batteries in the course of their operation, and, consequently, the lifetime — number of cycles. In this plane General indicator is the cost per unit of accumulated energy.
The use of lead-acid technologies in the battery industry should be assessed from the point of view of economic and environmental perspectives. Generalized economic parameter, the cost per unit of stored energy based on the number of cycles of the battery.
Today for series batteries, the lowest cost per unit stored energy to provide lithium-ion batteries. The corresponding value of the energy stored in lead-acid batteries is about 2 — 2.5 times higher. Thus, increasing the number of cycles a lead-acid battery in 2— 3 times, lead-acid technology will be the most economical for applications not requiring mobility and compactness (which is almost all energy and part of the transport applications). We can say that the increase in life of battery 2-3 times will mark a new stage of their application, will change the market for batteries in General.
Note that today there are scientifically reasonable prospect of increasing the number of cycles to 5 — 10 times or more. The management of the company "IPower" understands this, and already in plans for the construction and development of the plant included the establishment of testing and research laboratories, to build links with universities and scientific institutions of the Republic of Belarus.
Therefore, the establishment of the plant is not only a new step in the industrial development of the Republic of Belarus, but also opening a "window" of opportunity for innovative development on a global level.
With regard to the environmental issues of lead-acid technology, it should be said that they use a relatively small number of substances and compounds: lead, hydroxyd of lead, calcium, modifiers of electrode slurry, usually environmentally neutral materials based on carbon and mineral substances, and sulfuric acid based electrolyte.
Treatment of electrolyte worked for many decades and therefore does not carry threats, besides the neutralization of acid — cheap and simple chemical process.
The melting of lead is associated with the emergence of lead vapor. However, the vapor pressure of lead at production temperatures of the order of 350 With very small — of the order of 10-8 ATM, so a standard technological drawing, and especially the use of a deserted automated lines, which are planned to install at the factory", IPower" provide a safe environment in the production areas. The same applies to the shredding technology of the lead.
Other specific environmental risk factors in the production of lead-acid batteries no.
In this respect, competing technologies are Nickel-cadmium, lithium-ion carry more risks of more complex technology recycling and disposal, the greater toxicity of cadmium, the possibility of overheating and destruction of batteries at high loads and some others.
Planned battery plant is the first and only at present, the production target for the full production cycle batteries. The production will have a certain margin of power that will allow us to expand the range of batteries for different applications, and this is an obvious advantage for rapid development of other industries, including transport, energy, utilities, etc.
The most important effect of creating new production, which will be able to assess all the inhabitants of the Republic of Belarus will be some reduction of StaImost mass of batteries, which are known to all motorists.
Cost reduction, at the exit of production targets and in comparison with other suppliers will be driven by lower transport costs, use of advanced logistics technologies, when all movement components and materials consistent with the unified plan of production and supply.
We will remind, against the construction of a battery factory on the territory of FEZ "Brest" in Brest airport are the inhabitants of the surrounding settlements and the regional center. According to recent reports, has already collected more than 20 thousand signatures.
Besides, alarming and battery door to the airport.
Reference
The customer of the object is OOO "IPower" (Belarus), the contractor — Chinese "Angeliska foreign economic construction Corporation". The new plant will start full production cycle batteries. The first products they plan to release in September.
The total investment costs for the construction of the battery plant LLC "IPower" is, according to preliminary data $ 26 million.
The design capacity of the battery factory will amount to 2 million pieces of conventional rechargeable lead-acid battery, the ground launch complex — 1000 pieces.
This project is included in the State program of innovative development of Belarus for 2016-2020, and also in the list of projects that are crucial for innovation development of Belarus in accordance with the government resolution of 14 September 2017 No. 693.
