CR2450 battery

CR2450 battery technology: industrialization in 5 to 10 years

With the widespread implementation of the national demonstration operation policy and the active publicity of the media, pure electric vehicles, hybrid electric vehicles and other once high-tech energy-saving and environmentally friendly technologies have become more and more familiar and understood by ordinary people. However, in contrast to the popularity of the first two brothers, fuel-powered lithium battery vehicles, one of the three important technical routes of new energy vehicles, seem somewhat mysterious and silent. What kind of automotive technology is fuel-powered lithium battery vehicles? Does the current low-key mean that it is out of reach or insignificant?

Regarding the latter question, representatives and members from the field of new energy vehicles almost unanimously gave a negative answer. It is an exaggeration to say that in the eyes of these experts who have been immersed in the most cutting-edge scientific research front of the automotive industry for many years, the importance of fuel-powered lithium battery vehicles is definitely not less than or even surpasses electric vehicles.

According to the current progress of technology and industrial development, people may be able to hold the steering wheel of fuel-powered lithium battery vehicles in another 5 to 10 years.

The booming electric vehicles in recent years often make people mistakenly believe that fuel-powered lithium battery vehicles should be no different from the former. In fact, fuel-powered lithium battery vehicles have their own unique energy generation mechanism. Although it is still a type of electric vehicle, the energy of its battery is directly converted into electricity through the chemical use of hydrogen and oxygen without combustion. In the entire chemical reaction process, no pollutants will appear except water, which can be regarded as the most environmentally friendly type of vehicle. In the three vertical and three horizontal research and development pattern of new energy vehicles in my country, fuel vehicles, hybrid vehicles and pure electric vehicles together form the three verticals of the technical route.

In 40 to 50 years, traditional vehicles and three new energy vehicles will coexist for a long time. But in the longer term, if no other types of technology emerge during this period, fuel-powered lithium battery vehicles can be said to be the future direction of the automotive industry. Hu Liqing, member of the National Committee of the Chinese People's Political Consultative Conference and chairman of Shanghai Shenli Technology Co., Ltd. said.

However, wearing this high hat of the future direction does not mean that fuel-powered lithium battery vehicles are just a dream half a century later. According to the current progress of technology and industrial development, it may only be 5 to 10 years before people have the opportunity to hold the steering wheel of fuel-powered lithium battery vehicles.

As for fuel-powered lithium battery vehicles, they are of great importance in ensuring energy security, environmental safety, and boosting the core competitiveness of automobiles, and their development must be accelerated; at the same time, due to their common platform characteristics with hybrid vehicles and pure electric vehicles in terms of power systems, and their complementary characteristics with pure electric vehicles in terms of vehicle usage and driving range, fuel-powered lithium battery vehicles have the foundation and can accelerate their development. Zhen Zijian, deputy director of the Electric Vehicle Major Project Management Office of the Ministry of Science and Technology, explained. He believes that fuel-powered lithium battery vehicles will be able to enter the commercial sales stage through demonstration operation in 5 to 10 years, just like electric vehicles in the past two years.

Strong foreign counterparts are already speeding up in achieving industrialization and commercialization

Of course, for a technology that will span 50 years, entering demonstration operation is just the first step in a long march. What Chinese people need to see is that strong foreign counterparts are already speeding up in moving towards a higher stage of industrialization and commercialization.

According to data, in January 2011, Mercedes-Benz's B-class F-CELL fuel-powered lithium battery car completed a 125-day journey around the world. Daimler recently announced that it would advance the company's fuel-powered lithium battery car industrialization schedule from 2015 to 2014; General Motors' 100 Chevrolet Equinox fuel-powered lithium battery cars completed 1.4 million miles of actual driving in 2010 alone; at the challenge held in Germany in May 2011, fuel-powered lithium battery cars from mainstream automobile companies such as Toyota, Honda, General Motors, Mercedes-Benz, Audi, and Hyundai competed with each other and reached a very high level... In addition to the vehicles themselves, the supporting infrastructure required for fuel-powered lithium battery cars has also received strong support from foreign governments and industries. As early as 2009, seven world-renowned automobile companies jointly issued a statement calling on governments and energy companies to speed up the construction of fuel-powered lithium battery infrastructure. Then, major German automakers and the government launched a plan to establish a nationwide comprehensive hydrogen refueling network that can support 100,000 electric and fuel-powered lithium battery vehicles per year by 2015; in 2010, 13 Japanese oil companies also formulated a plan to vigorously develop hydrogen energy infrastructure by 2015, reaching 1,000 hydrogen refueling stations by 2025 to supply 2 million fuel vehicles...

Foreign automakers are accelerating their research in the field of fuel-powered lithium battery vehicles, aiming at the commanding heights of new energy vehicle technology, and are quietly preparing to achieve initial product sales in 2015. Zhen Zijian expressed his concerns about the rapid pace of foreign automakers in the field of fuel-powered lithium battery vehicles. This intensive pace cannot be seen from the market or the media, and it is hidden in the deep level of foreign companies' innovation links. But our new energy vehicle experts have been closely following the trends of foreign automakers and can feel very great pressure!

In this regard, Ouyang Minggao, member of the National Committee of the Chinese People's Political Consultative Conference and leader of the overall group of the major project of energy conservation and new energy vehicles in the 863 Plan, has a more intuitive feeling. Recently, Japan held a highly professional new energy exhibition, with 120,000 visitors. At the exhibition, we found that the fuel-powered lithium batteries, which have always been considered far away, have been commercialized by the Japanese. Ouyang Minggao said that the speed and efficiency of Japanese companies' research and development far exceeded his expectations. What makes him even more stressed is the construction and integration capabilities of foreign car companies in the industry chain. In fuel-powered lithium battery cars, there are specialized companies making even small screw caps. The entire industry chain is very long and very complete. Ouyang Minggao said.

In short, when Chinese companies are still watching or struggling to explore, international competitors are already quite mature in technology. Some people may ask why foreign companies are not making efforts now. Zhen Zijian's point of view is: the reason why they are willing to wait for three years is more to further reduce costs and prepare supporting infrastructure.

At present, my country's fuel-powered lithium battery industry lacks a mature upstream industrial chain, and most key materials and components rely on imports

So, what is the gap between the development of my country's fuel-powered lithium battery vehicles and the world's advanced level?

In Hu Liqing's view, the first is the field of fuel-powered lithium batteries. If fuel-powered lithium batteries are the heart of fuel-powered lithium battery vehicles, then the key technologies and materials for producing fuel-powered lithium batteries are the core of the core.

Hu Liqing said that at present, my country's fuel-powered lithium battery industry lacks a mature upstream industrial chain, and most key materials and components rely on imports, resulting in overall control by others. For example, many companies have to buy diaphragms from DuPont in the United States, while key components such as air compressors are often not available even if you have money.

Specifically, in terms of fuel-powered lithium batteries, namely battery stacks, the important ones are proton exchange membranes, catalysts, carbon diffusion layer materials, and bipolar plates. Other key components include air compressors, high-efficiency radiators, special valves, and high-pressure hydrogen storage tanks. Among them, the 70MPa on-board ultra-high pressure hydrogen storage tank is expected to be commercialized within 2 to 3 years, while my country can only produce 35MPa specifications; the life of the fuel-powered lithium battery engine system for American buses has reached 5,000 hours, while my country's has not yet exceeded 3,000 hours.

Zhen Zijian believes that in terms of the industrialization of fuel-powered lithium battery vehicles, the country, companies and relevant social parties should attach great importance to, systematically plan and take practical actions for the next 5 to 10 years. In the near future, we can choose public service vehicles as the entry point, increase the intensity of demonstration assessment and business model cultivation, and continuously improve the core technology of our products, laying the foundation for fuel-powered lithium battery vehicles to enter the mainstream market of passenger cars and commercial vehicles.

What really determines the future of my country's fuel-powered lithium battery vehicles is the country's vision and the attitude of the industry

Faced with the clear gap between China and foreign countries, people may raise such questions: Will my country's fuel-powered lithium battery vehicles, surrounded by strong enemies, end up in the same predicament as the traditional automobile industry?

In fact, despite the large gap with foreign countries, my country has made a good start in the field of fuel-powered lithium battery vehicles and hydrogenation infrastructure through the major science and technology projects of electric vehicles and major energy-saving and new energy vehicle projects of the Ministry of Science and Technology during the 10th and 11th Five-Year Plans: SAIC, FAW, Chery, Changan and other vehicle manufacturers have formed a fuel-powered lithium battery passenger car and commercial vehicle power system technology platform with independent intellectual property rights with industry-university-research cooperation with Tongji University, Tsinghua University, Shanghai Ran Power, Xinyuan Power, Shenli Technology, etc., and developed corresponding fuel-powered lithium battery vehicle products for actual demonstration operation assessment. In the 2008 Olympic Games, 23 fuel-powered lithium battery vehicles demonstrated 76,000 kilometers. By the 2010 World Expo, this number rose to 196 vehicles and 910,000 kilometers. At present, Beijing and Shanghai have built four fixed hydrogen refueling stations and two mobile hydrogen refueling stations, of which the latter took the lead in exploring the industrial by-product gas hydrogen supply infrastructure network… But in Hu Liqing's view, what really determines the future of my country's fuel-powered lithium battery vehicles is the country's vision and the attitude of the industry. He said that the country should respond to some of the current doubts and even denials of fuel-powered lithium battery vehicles through more powerful policies, strengthen support for the research and development of key material technologies for fuel-powered lithium batteries, and actively play the role of companies as innovation subjects. In addition, it should also establish an industrial technology innovation alliance to concentrate resources, achieve breakthroughs in common industrial technologies, and establish a long-term mechanism for demonstration and promotion. A big country should have a vision for the next few decades. Hu Liqing said. Technology Hot Words Fuel-powered lithium battery vehicles The working principle of fuel-powered lithium battery vehicles is that in the fuel-powered lithium battery carried by the car, the hydrogen as fuel reacts chemically with the oxygen in the air, thereby generating electricity to start the motor and drive the car. Methanol, natural gas and gasoline can also replace hydrogen, but very little carbon dioxide and nitrogen oxides will appear. But in general, this kind of chemical reaction produces only water in addition to electricity. Therefore, CR2450 battery vehicles are called authentic environmentally friendly vehicles.

Hydrogen fuel for CR2450 battery vehicles can be obtained in several ways. Some vehicles carry pure hydrogen fuel directly, while others may be equipped with fuel reformers that can convert hydrocarbon fuels into hydrogen-rich gas. Individual CR2450 battery batteries must be combined into CR2450 battery batteries to obtain the necessary power to meet the requirements of vehicle use.
