Comparison of advantages and disadvantages of hydrogen fuel power battery and ternary lithium battery

The ternary data has advantages in battery specific energy, specific power, large-scale charging, low temperature function, etc., while in terms of cycle function, lithium iron phosphate data has obvious advantages. In terms of safety, lithium iron phosphate batteries are better than ternary data. People used to say that the way hydrogen stores energy is much more dangerous than gasoline. Is this true? How does the hydrogen fuel power battery work? How does its safety plan look like? Please go to the following to translate for us! Same as the battery pack, the hydrogen tank is equipped with the function of storing hydrogen, and the fuel power cell reactor Equipped with the function of converting hydrogen and oxygen into electricity and water. Together, they form a battery pack equivalent to an electric vehicle, which can continuously supply power to the electric motor and the vehicle's electrical appliances. The benefits of hydrogen fuel power cells are obvious. The power is highly modified, the process is quiet, and not too much cooling. This is why Toyota Mirai can travel more than 700 kilometers with only 5 kg of hydrogen. Hydrogen fuel power battery has the characteristics of high energy density and high energy modification ability. The core technology of fuel power cell reactor is proton exchange membrane and catalyst. These skills are mainly monopolized by large European and American companies and do not constitute large-scale industrialization in our country. So it is easy to see why the reactor is listed as a core skill, so why is the gas tank also a core skill? The hydrogen storage tank is made of carbon fiber + composite materials, and its sealing performance and durability determine the function of the hydrogen storage tank. Just as the processing level of equipment in a large country is the same, in the industrial and civilian fields, the function of sealing information is also an important basis for measuring the manufacturing level of a large country. Many European and American countries keep confidential the formulation and manufacturing process of high-performance seal information. This is why in the traditional automotive field, the complex braking systems and general rail systems for gasoline and diesel engines come from European and American suppliers, and the core skill of these suppliers is sealing. The same is true for hydrogen fuel-powered battery cars. They need to carry more hydrogen to increase the mileage, and pressure vessels that can store hydrogen are used to determine how much hydrogen they can carry. Since hydrogen has a small density, it must be compressed, even liquefied at low temperatures, and stored in the center of the pressure vessel to achieve the required energy density. The greater the pressure the container bears, the more hydrogen it carries per unit volume. The greater the pressure that the container can withstand, the higher the conditions of the sealing function and pressure resistance function. Toyota Mirai is a global leader in the field of hydrogen storage, and the model is currently in mass production. Nevertheless, it still requires two large fuel tanks for 5kg of hydrogen, so it occupies a lot of space in the rear of the car, which makes it different from traditional electric cars in terms of styling and relatively high rear height. The fuel cell reactor is the place where chemical reactions occur during the operation of the fuel cell vehicle. It can continue to operate as long as it continues to supply a small amount of hydrogen. In the event of a hydrogen leak or a safety accident, it can sensitively stop the supply of hydrogen to prevent hydrogen from burning. As you can imagine, the fuel tank is most likely to make a fuel-powered car safe. Therefore, safe knocking must be fully considered when planning gas storage tanks: on the one hand, the data requirements of the gas storage tank shell are light; on the other hand, the demand is also strong enough to withstand collisions. However, no matter how strong the data is used to make the fuel tank shell, it can only guarantee a safe knock under unpreventable speed conditions. However, the actual driving speed must be much higher than the laboratory speed to cause a safe collision. So once the hydrogen storage tank splits, causing the hydrogen and air to leak out, will the explosion happen immediately? In fact, for safety reasons, there is no Thought about locking it up. Because the hydrogen pressure inside the hydrogen storage tank is very high, an emergency pressure relief valve is designed on the gas storage tank. In the event of a hydrogen leak or fire, the emergency relief valve will automatically open and release the hydrogen in the tank.
