"Recently, nanoflowcell, an electric vehicle brand from Liechtenstein, released a new quant 48volt concept sports car, which adopts the latest low-voltage flow battery technology, with a maximum power of 762 HP, a maximum speed of 300km / h, an acceleration of 2.4S from 0-100km / h, and a maximum range of more than 1000km.
I believe you have long been used to such news, but in fact, for our ordinary consumers, this kind of "surreal concept car" is far from us, and the most important thing is the price According to sources, the future price of this car will be as high as about RMB10 million. However, the reason for mentioning this news is that this concept car uses an unusual "liquid flow battery".
The most common types of batteries for electric vehicles are lithium batteries, nickel metal hydride batteries, etc. (of course, there are many small categories, which will not be mentioned one by one). For liquid flow batteries, the brand first launched concept products during 2014, and the Geneva auto show, which opens in March, will bring real vehicles, Next, the author introduces what is a liquid flow battery And whether the liquid flow battery can become the mainstream driving mode of electric vehicles in the future.
Flow battery
Loosely speaking, liquid flow battery belongs to "liquid" battery, which does not belong to the type of solid-state battery, which can be learned from the name. What is the flow battery?
In fact, the liquid flow battery was not first used in electric vehicles as a battery system. Japan used the liquid flow battery in power station peak shaving, wind energy storage and other facilities, which is enough to prove the strength of the reserves of the liquid flow battery.
Of course, if the large storage of liquid flow battery is an advantage, it is both happy and sad to use it in pure electric vehicles. If the storage is large, the natural volume is large. For a car, the large battery is not suitable for loading on the car. This is the contradiction.
(however, it is reported that the previously mentioned concept car of nanoflowcell brand has developed a high-density liquid flow battery, which will be introduced below)
Advantages of liquid flow battery
The following two figures clearly show the working principle of the flow battery:
In fact, the biggest difference between liquid flow battery and ordinary lithium battery pure electric vehicle is that liquid flow battery plays an "engine" in the overall structure of the vehicle, rather than our common energy storage mechanism. The positive and negative electrolyte tanks continuously provide fuel to the liquid flow battery, and the redox reaction occurs in the film to generate current.
Having said so much, you must be most concerned about its advantages, that is, the advantages of liquid flow battery compared with lithium battery:
Rated power and rated energy are independent. The power depends on the battery stack and the energy depends on the electrolyte. The amount of electrolyte can be increased at will to increase the battery capacity.
The storage life of the battery is unlimited and the storage life is long. The electrolyte is recycled without deterioration, but the diaphragm resistance of the battery increases after long-term use.
Instant recharging can be achieved by changing the electrolyte.
In fact, there are many advantages of liquid flow battery. Since it has so many advantages, why not popularize it? The most important reason is that the technology is immature and the cost is very expensive, which makes it impossible to popularize.
The concept of liquid flow battery launched by nanoflowcell brand has been shown to the world as early as 2014. After three years of technology development and precipitation, it will finally usher in the true face of the concept car at the upcoming Geneva auto show.
What is the "magic" of the nano flowcell brand quant 48volt concept car? Does it really solve the technical difficulties of liquid flow battery?

Innovative energy
nanoFlowcell？ It is the most innovative and powerful energy storage system in mobile and fixed applications. Compared with conventional batteries, nanoflowcell provides energy in the form of liquid electrolyte (bi-10n), which can be stored away from the battery itself. Like the conventional flow cell, the positively charged and negatively charged electrolyte liquid are stored in two tanks respectively, and pumped through the converter (the actual unit of the nano flow cell system) in a separate circuit like the traditional flow cell or fuel cell. The two electrolyte circuits are separated only by permeable membranes. Once the positive electrolyte solution and the negative electrolyte solution pass through each other on either side of the converter membrane, ion exchange occurs. This converts the chemical energy combined in Bi ion into electricity, which can then be directly used in electric consumers.
Scalable energy
Using nanoflowcell? Technology, the separation of energy converter and energy storage medium means that the stored energy is no longer dependent on the unit size. This is the difference between liquid flow battery and traditional battery. Using nanoflowcell?, The available energy depends on the concentration of electrolyte in the electrolyte liquid and the volume of the electrolyte container. Because of its unlimited scalability, nanoflowcell can adapt to a variety of applications.
Rapid charge discharge
By changing the electrolyte, the instantaneous recharging is realized, which is also the characteristic of liquid flow battery.
Innovative charge carrier
Here's another sentence:
Bi ion is nanoflowcell? Liquid energy carrier. The power density of electrolyte is equivalent to that of lithium-ion battery, but its energy density is five times that of lithium-ion battery. Bi ion is the perfect fuel for environmentally compatible and sustainable electric drive.
Bi ion is for nanoflowcell? The power characteristics of the system are very important. Through years of research, the company has developed special charge carriers, so that the power and energy density of hydrolysate are significantly higher than all liquid batteries on the market.
High energy density
The company's developed charge carriers allow significantly higher concentrations of previous electrolytes in conventional flow cells. Compared with the electrolyte tank in fixed equipment with a volume of thousands of liters, only the tank volume of conventional vehicles is required to achieve the performance of quantino 48volt. In the current state of development, an energy density of 600 WH / L is achieved using bi ion. Compared with lithium-ion batteries used in most electric vehicles, nanoflowcell running on Bi ion? It can provide enough energy, up to 5 times that of conventional electric vehicles.
Can mass production and technical problems
These are just the advantages of the power system. The following is the advantages of the concept car itself
Hub motor technology
The quant 48volt concept car is equipped with motors in four wheels, which can realize the independent torque output of four wheels. This is equivalent to the torque between wheels that do not require differential adjustment.
Long range
The company has solved the problem of fluid battery density. According to the range given by the official, the range of the new car will exceed 1000km, which is also a long range that can not be reached by the published technical level.
Powerful power system
According to official data, the maximum power of the new car is 762 horsepower, the maximum speed can be as high as 300km / h, 0-100km / h, and the acceleration time is 2.4S.
If there are disadvantages, the author believes that the biggest disadvantages are technical problems and expensive prices.
Although the technology of this concept car is so advanced, it still can't achieve the level of mass production. Only from the perspective of development funds, the foreign media's judgment on the price of a car will not be less than RMB 10 million.
Unable to reach the mass production level, even how strong the technical reserve is, it will stop at the concept. As consumers, we cannot immerse ourselves in the beautiful concepts created by these companies. Looking at today's electric vehicle technology, it still takes some time to achieve such a high level. I'm afraid it's still unknown to really bring qualified products to the market.
Write at the end
In fact, it is not boasting how advanced the technology of the quant 48volt concept car is. Of course, these only exist in the theoretical value. It is an indisputable fact that electric vehicles are indeed the development trend of the future automobile industry. No matter how strong the promotion efforts of the government or enterprises are, our consumers only care whether the products are convenient for daily life.
What is the purpose of buying a car? The definition of a car is nothing more than tools, props and toys. The vast majority of electric vehicles on the market are defined as tools. However, facing a series of social problems such as charging piles, they can not be alleviated. It can be said that they spend money to find guilt. To borrow the words of the famous big V in the car circle, do you eat for charging or charge for eating?
In short, there are still some doubts about whether electric vehicles are environmentally friendly. I believe these are by no means what most car owners really care about, and when to solve the charging problem and stability problem under the car is very important, otherwise everything is "cheating money"., Read the full text, technical section
