Analysis of the working principle of flow battery

Battery knowledge explains the working principle of flow battery 1. Flow battery analysis Flow battery belongs to the category of liquid battery, not the category of solid battery, as its name implies. What exactly is a flow battery? Recently, the Liechtenstein brand electric car nanoFLOWCELL launched a new concept sports car QUANT48Volt, using the latest low-voltage flow battery technology, the maximum power will reach 762 horsepower, the maximum speed is 300 km/h, 0-100 The acceleration is 2.4 seconds at km/h, and the maximum mileage may exceed 1,000 kilometers. I believe we are used to such news, but in fact, for our ordinary customers, this surreal concept car is still far away from us. The most important thing is the price. According to sources, the future price of this car will be Up to 10 million yuan. However, the news mentioned that because the concept car uses an unusual mobile battery. Varieties of electric vehicle batteries, our most common ones are lithium batteries, nickel-metal hydride batteries, etc. (of course there are many small categories, don't mention them one by one), and flow batteries. The earliest brand introduced a concept product in 2014. And the opening ceremony of the Geneva Motor Show in March will bring a real auto show. Next, I will analyze what fluid batteries are for us and whether flow batteries can become the mainstream driving method of electric vehicles in the future. Mobile batteries belong to the category of liquid batteries, not solid-state batteries, as its name implies. What exactly is a flow battery? In fact, the flow battery was not originally used as a battery system for electric vehicles. Japan's use of flow batteries in equipment such as power station peak shaving and wind energy storage has proved the power of flow battery reserves. Of course, if liquid battery storage is an advantage, then using pure electric vehicles is both a pleasure and a pleasure. Large capacity means large natural capacity. In the case of automobiles, large batteries are not suitable for automobiles. This is an opposing view. (However, according to sources, the previously mentioned nanoFLOWCELL concept car is easy to launch a high-density flow battery, which will be described below.) 2. Advantages of the flow battery The following two diagrams clearly show the flow unit In fact, the biggest difference between the flow battery and the ordinary lithium battery pure electric vehicle is that the flow battery acts as an engine in the entire structure of the car, rather than our common energy storage mechanism. The positive and negative electrolyte tanks continue to supply fuel to the flow cell, and the flow cell undergoes an oxidation-reduction reaction in the membrane to generate current. In summary, we must pay the most attention to its advantages, that is, the advantages of liquid flow batteries related to lithium batteries: the rated power and rated energy are independent, the power depends on the battery pack, and the energy depends on the electrolyte. The amount of electrolyte added can be free to achieve the purpose of increasing the battery capacity. ●The battery has unlimited storage life and long storage life. The electrolyte is circulated and there is no problem of deterioration, but after long-term use, the gap resistance of the battery increases. ●The electrolyte can be replaced to complete instant charging.
