What is the advantage of vanadium battery relative to the lithium battery?

Source: 2020 - 03 - 29 15:20 hits: vanadium battery relative to what is the advantage of lithium battery? Lithium battery can be replaced in the future? Vanadium flow batteries relative to the advantage of lithium-ion batteries are as follows: a, convenient planning. A system can be as big as your refrigerator, or as big as the neighbor of the substation, sufficient power supply your home one day to one year. Second, the service life. You can use it for half a century. Third, the security is better. Taboo in front of the lithium ion battery overcharge, large current and no pressure and no fire. The first question is: low energy density. Don't expect to use it on your phone. After 20 years of development, vanadium flow batteries has become a complicated energy storage technology. Main application direction for new type of electric field and MWh large planning pumped-storage power station. Compared with the lithium ion battery as the main mobile power supply, the connection between them is like a spoon and a shovel, no alternative space to each other. All vanadium flow batteries's main rival is a large energy storage technology, such as hydraulic and compressed air energy storage, as well as the flow batteries used in other systems. A, shopping center there is a village called li village in the mountains, mountain road is very far from electricity. In the village a few years ago, with a generator, but diesel is very valuable. When the sun goes down, dim light has become a luxury. At the end of the year will come, with cold north wind, the county electrician lidle appeared on the winding mountain road, behind the tricycle pulled a few shiny big blackboard. Alas, the boss boss huang is the solar energy, owe a three hundred and fifty million, his sister-in-law to run. We have no way to, to pay by photovoltaic panels. It is said that if you put it in the sun, it can generate electricity. It does not burn oil boil water. I took two pieces back, the children in the evening to read a book, cui flower will sew. Lee doghi photovoltaic stents is ready, but just like leonardo's flashlight, it is not in the evening the sun is the purpose of this story illustrates the plight of new power class. Lee's problems are similar to wind power engineers are faced with the problem. To some extent, we take for granted the power grid is the world's largest and most powerful machine, but the strange thing is, it must balance the energy budget of each moment, roaring turbine output and consumption of light in the north China plain in pithead power plant on tens of thousands of houses thousands of miles away. This is a long journey of walking a tightrope. There is no doubt that we have a lot of control to maintain a balance, but there will always be natural disasters, such as the United States and Canada in 2003 blackouts and snow disaster in 2008, the China southern power grid. New power grid to power engineers brought a bigger problem: the weather. It is hard to cope with the user's demand, this is a miracle of god that day, ╯￣Д￣) ╯ ┻ ━ 2012 in jilin province ┻ to abandon the wind rate of 32%, and a third of the power lost in the wind. In addition to the local consumption ability is limited, problems also exist in control. Wind power and photovoltaic short-term volatility is very serious, hard and grid synchronization, commonly known as' waste electricity, if direct grid will lead to the entire power system instability. The problem is that we don't have like leonardo Da Vinci's flashlight, mechanism of stored energy on the grid. If we can realize cast high low power, peak adjustment, abandon the wind and deal with the problems, in the jargon, will be solved. Now you just need to adjust the output of the generator can meet the requirements. Generating set, however, usually under rated power of the supreme power, the output of the frequent changes necessary to cause a decline in power. So in terms of the existing power system, energy storage technology also has implications for energy conservation and emissions reduction.
