Are hydrogen fuel cell-powered 18650 lithium ion battery 3.7v vehicles a technological breakthrough for hydrogen energy utilization?

Chen Qingtai, chairman of the my country Electric Vehicle Hundred People's Association, said at the Hydrogen Energy Industry Innovation and Development Forum held at Tsinghua University: Hydrogen energy is a universal energy source; hydrogen fuel cell-powered 18650 lithium ion battery 3.7v is a universal conversion device; in the development and utilization of hydrogen energy, the most difficult and most typical application scenario is hydrogen fuel cell-powered 18650 lithium ion battery 3.7v vehicles; hydrogen fuel cell-powered 18650 lithium ion battery 3.7v vehicles are a technological breakthrough for hydrogen energy utilization.

Chairman Chen Qingtai has raised "hydrogen energy", "hydrogen fuel cell-powered 18650 lithium ion battery 3.7v", and "hydrogen fuel cell-powered 18650 lithium ion battery 3.7v vehicles" to a new height. How to understand it?

1. What does universal energy mean?

Universality and pertinence are corresponding. The universality of things comes from the commonality and laws of things; energy is a material resource that supplies various capabilities and power for human production and life, and is an important material basis for the national economy. For example, primary energy sources include coal, gasoline, and diesel, and secondary energy sources include electricity.

What we need to think about is that hydrogen does not exist under normal natural conditions. Hydrogen is not a primary energy source. Through processing, such as electrolysis of water to produce "hydrogen", it consumes "electric" energy; industrial "hydrogen" purification, compression, etc. also consume "electric" energy; if hydrogen energy is a universal energy source? It cannot compare with the universality of "electricity".

2. Is hydrogen fuel-powered 18650 lithium ion battery 3.7v a universal conversion device? How to understand?

Hydrogen fuel-powered 18650 lithium ion battery 3.7v is a device that converts "hydrogen" into electrical energy. Everyone can understand this. But how to understand the universality of hydrogen fuel-powered 18650 lithium ion battery 3.7v?

The question to think about is that the internal combustion engine is a universal energy conversion device, so there is the beginning of the industrial revolution; the engine is a case of the application of the internal combustion engine to transportation vehicles, so there is the vigorous development of the automobile industry; where is the universality of hydrogen fuel-powered 18650 lithium ion battery 3.7v specifically reflected? Hydrogen fuel-powered 18650 lithium ion battery 3.7v must be made similar to automobile engines; hydrogen fuel-powered 18650 lithium ion battery 3.7v engines must exceed the level of fuel engines to be convincing. At present, it is just a saying that hydrogen fuel-powered 18650 lithium ion battery 3.7v engines are a universal conversion device.

3. Hydrogen utilization is the most difficult, and the most typical application scenario is hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles

Japan is a leader in the research and development of hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles, but Japan has not really promoted and applied fuel-powered 18650 lithium ion battery 3.7v vehicles. It can be said that promoting and applying hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles is indeed the most difficult; hydrogen fuel-powered lithium batteries are widely used, and have been used for many years in rescue and emergency. However, the application in these places basically does not take into account the cost, or in other words, the use of hydrogen fuel-powered lithium batteries in these places cannot be considered as real application; hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles are promoted and applied, and then it can be said that hydrogen energy utilization has become the most typical.

4. Can hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles be promoted? The key lies in the government

Where is the hydrogen fuel production chain? Hydrogen is not a primary energy source. "Hydrogen" can be decomposed by electrolysis of water. Where is the electricity? If we still use the current electricity to decompose "hydrogen", isn't it more economical to charge the battery with electricity?

Where is the hydrogen fuel supply chain? The power grid is mature, and natural gas is a primary energy source. We can lay a transportation pipeline trunk line and then transport it to the gas station with a special vehicle. Hydrogen fuel is not a primary fuel. The hydrogen fuel supply chain cannot be built like a gas station or a gas station, and it cannot be built like a gas station, which forms a network of hydrogen fuel supply chains as transportation nodes.

Therefore, the conclusion that hydrogen energy is a universal energy source still lacks evidence. At present, we can see that the universality of hydrogen energy cannot be compared with fuel, electricity, and natural gas. Hydrogen energy is a universal energy source. If it can be scientifically demonstrated, the government will be able to actively coordinate social resources and build a hydrogen fuel supply chain.

V. The shortcomings of electric vehicles are objective

Cars are civilian products. At present, my country's electric vehicles are developing rapidly, and its important driving force is the government. The government sees the development trend 10 years later. The people think about the stability of product quality, the economy of price, and the convenience of use.

At present, the shortcomings of electric vehicles are: short cruising range, long charging time, and inconvenient charging. The above is compared with the current development level of fuel vehicles. With the active support of the government, if the above three indicators of electric vehicles lag behind those of fuel vehicles for a long time, that is, if the shortcomings of electric vehicles cannot be overcome, electric vehicles cannot develop.

How to overcome the above three shortcomings?

Power lithium-ion battery factories are actively innovating technology and steadily improving the specific energy of power lithium-ion batteries to increase the driving range. At present, the speed is relatively slow; power lithium-ion battery factories are finding a balance between specific energy and specific power, and are actively developing high-rate charging power lithium-ion batteries to improve charging efficiency. At present, the speed is relatively slow; the government is actively deploying charging stations and charging piles, basically maintaining the scale of electric vehicle development. At present, the speed is relatively fast.

From the development trend, some current measures have a mitigating purpose, but cannot completely make up for the shortcomings of electric vehicles.

6. Can hydrogen batteries make up for the shortcomings of electric vehicles?

On-board hydrogen energy batteries are generators that can charge on-board batteries and can charge power lithium-ion batteries during vehicle operation; on-board hydrogen energy batteries and on-board power lithium-ion batteries are not contradictory. If there is time (at night), they can be charged. If time is tight, hydrogen can be added. The principle and efficiency are the same as adding natural gas. On-board energy battery power generation meets environmental protection requirements, while fuel booster power generation does not meet environmental protection requirements;

Where does hydrogen come from? The government has already laid out, so where does hydrogen come from? That is not a problem. Under the leadership of the government, hydrogen batteries can make up for the shortcomings of electric vehicles. The development of electric vehicles in my country is achieved under the leadership of the Chinese government. The Chinese government has the ability to develop electric vehicles, and naturally has the ability to develop hydrogen batteries to make up for the shortcomings of electric vehicles.

VII. The universality proposition is novel and high-level

In the past, when it came to the development of fuel-powered lithium batteries, the reason given by experts was that hydrogen energy is the ultimate energy source. The author believes that this proposition is somewhat empty. For example, there have been recent reports that "combustible ice" has been discovered in Hainan, my country, and shale gas is also a new fuel, which are all available energy sources in the future.

Chairman Chen Qingtai proposed: hydrogen energy is a universal energy source; hydrogen fuel-powered lithium batteries are a universal conversion device; in the development and utilization of hydrogen energy, the most difficult and typical application scenario is hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles; hydrogen fuel-powered 18650 lithium ion battery 3.7v vehicles are the technical breakthroughs in the utilization of hydrogen energy.

Among them, the universal proposition is more realistic, novel and high-level. The reason is that universality can be verified, and universality can be improved through efforts.

In other words, if hydrogen energy is not a universal energy source, it is not worthwhile for the government to spend a lot of money to promote its application. Even if hydrogen energy does not have the same universality as "electricity", its universality is visible for electric vehicles.

If hydrogen fuel cell lithium batteries are not a universal conversion device, there is no need to promote them in cars. There are many new technologies (new conversion devices) that want to be applied in cars, but in the end they cannot be used. What is the reason? They are not universal.

In summary, the universality proposed by Chairman Chen Qingtai is more practical, innovative and high-level. It has practical guiding significance for the development of hydrogen energy industry and hydrogen energy vehicles.
