It will take another 3 to 5 years for my country's hydrogen 18650 lithium battery cells technology to reach the technical maturity stage

Hydrogen 18650 lithium battery cells vehicles are an important technical route for my country's new energy vehicle industry and one of the "three horses" of new energy vehicles. However, due to the fact that the focus of industrial development in the past period of time has been mainly on pure electric and plug-in hybrid vehicles, the industrialization process of hydrogen 18650 lithium battery cells vehicles has been 10 years slower than that of pure electric vehicles. After being "dormant" for nearly 10 years, hydrogen 18650 lithium battery cells vehicles have finally come to the fore. In the past two years, the domestic attention to hydrogen energy and 18650 lithium battery cells vehicles has been unprecedentedly improved, from the establishment of the China Hydrogen Energy and 18650 lithium battery cells Industry Innovation Strategic Alliance led by the State Energy Investment Group in early 2018 and participated by many central enterprises such as the State Grid Corporation of China, to the first time this year that hydrogen energy was written into the government work report. From local governments to the central government, the importance of the development of hydrogen energy and 18650 lithium battery cells vehicles has been raised to an important position. "Why has hydrogen energy been so popular in the past two years? Because the petroleum, chemical, steel, and energy industries are closely related to hydrogen energy. Steel coking produces hydrogen, chemical chlor-alkali production produces hydrogen as a byproduct, coal gasification produces hydrogen, and petroleum refining uses hydrogen, etc. These industries are currently some of the industries that the country's supply-side structural reform needs to reduce overcapacity. These industries are probably more than three times larger than the automotive industry, that is, more than 30 trillion yuan in output value, and the petroleum and chemical industries alone have an output value of about 15 trillion yuan. For such a large industry, hydrogen energy is a very good choice to seek a way out for green development and transformation and upgrading. In short, the hydrogen energy industry chain is very long, with a large number of stakeholders and a large number of people employed, which has a very obvious driving effect on the industry." Ouyang Minggao, an academician of the Chinese Academy of Sciences and a professor at Tsinghua University, gave his own understanding of the hot phenomenon of the hydrogen energy and 18650 lithium battery cells vehicle market. In addition, due to the inherent defects of pure electric vehicles in terms of driving range, charging time, and heavy-load transportation, hydrogen 18650 lithium battery cells vehicles are also considered to be an important solution to solve the user pain points of new energy vehicles in the commercial field. Wei Wei, president of Zhangjiagang Hydrogen Cloud New Energy Research Institute, said that the development characteristics of hydrogen 18650 lithium battery cells vehicles will be mainly commercial vehicles, which have different application fields from pure electric vehicles. Many people may think that hydrogen 18650 lithium battery cells vehicles are here to subvert pure electric vehicles, but this is not the case. The two technical routes are complementary, mutually supportive, and develop together, and they coexist in the long term. Ouyang Minggao holds the same view. Since the hydrogen 18650 lithium battery cells power system not only has hydrogen storage bottles, but also hydrogen 18650 lithium battery cells engines and auxiliary batteries, the size of hydrogen 18650 lithium battery cells cars is especially challenging for compact cars. In addition, the use of liquefied hydrogen is the future development direction of hydrogen 18650 lithium battery cells vehicles. This is easy to achieve on trucks and buses, but it is difficult to apply it to passenger cars, because passenger cars often have to be put in underground garages, and liquid hydrogen has evaporation characteristics. Ouyang Minggao introduced the current status of the development of 18650 lithium battery cells vehicles in my country. First, the deep hybrid power of 18650 lithium battery cellss and power batteries is the technical feature; second, 18650 lithium battery cells commercial vehicles are the main body; third, type III compressed hydrogen bottles are the mainstream way of on-board hydrogen storage. At present, the key area for the promotion of hydrogen 18650 lithium battery cells vehicles in my country is the commercial vehicle field. The number of hydrogen 18650 lithium battery cells commercial vehicles in my country has reached 3,500, ranking first in the world. Hydrogen 18650 lithium battery cells technology is developing rapidly. In recent years, my country's hydrogen 18650 lithium battery cells engine technology has made significant progress. It has evolved from the first generation of 18650 lithium battery cells engines to the third generation of 18650 lithium battery cells engines. The power density of the stack has reached 3 kilowatts per liter, and the volume has been able to achieve the same as that of a traditional four-cylinder internal combustion engine. However, there is still a certain gap with the international advanced level in terms of stack cycle life. Ouyang Minggao pointed out that although there is still a certain gap between my country's current hydrogen 18650 lithium battery cells technology and the world's advanced level, thanks to the vast market for hydrogen 18650 lithium battery cells vehicles in my country, the large number of participants, and the abundant resources invested by all parties, the technology is progressing rapidly. In 3 to 5 years, my country's hydrogen 18650 lithium battery cells technology will be synchronized with the international advanced level and reach the stage of technological maturity. "The huge domestic market is the most powerful driving factor for the development of hydrogen 18650 lithium battery cells vehicles in my country." Wei Wei said that the scale of the Chinese market is so large that once the market starts, it will attract many companies to enter. Through the increase in the localization rate, coupled with the scale effect, the cost will be greatly reduced. At present, many advanced technologies of hydrogen 18650 lithium battery cells vehicles have not yet been industrialized. The industrialization process of these technologies in my country may be faster than that in foreign countries because my country has the largest market in the world. Wei Wei introduced that my country's development plan for hydrogen 18650 lithium battery cells vehicles is to exceed 10,000 vehicles by 2020, reach 50,000 vehicles by 2025, and exceed one million vehicles by 2030. It is currently in the development stage of "10 cities and 1,000 vehicles". While the pace of development of hydrogen 18650 lithium battery cells vehicles is steady, it is also time to pay attention to practical problems in the development process. Ouyang Minggao pointed out that the main challenges facing the development of hydrogen 18650 lithium battery cells vehicles in my country are hydrogen energy technology and cost issues. my country's hydrogen energy technology lags behind 18650 lithium battery cells technology. Traditional hydrogen energy technologies such as alkaline electrolyzers and compressor refrigeration hydrogen liquefaction have problems of low efficiency and high cost, and the entire industry chain needs to jointly promote technological breakthroughs.
