18650 battery 3500mah lithium

　　18650 battery 3500mah lithium and pure electric power are just springboards. Is hydrogen fuel cell the final choice for energy solutions?

　　Hydrogen fuel cells use the chemical element hydrogen to create batteries that store energy. The basic principle is the reverse reaction of electrolyzing water, supplying hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load.

　　"Fuel cells are very important. They are the ultimate energy solution." Recently, Sun Shigang, academician of the Chinese Academy of Sciences and professor of Xiamen University, said in an interview with Battery China.com that compared with 18650 battery 3500mah lithium, fuel cells have higher power density and more driving force. powerful. He pointed out that fuel cells can use hydrogen or other biofuels, of which hydrogen is the most ideal.

　　Yu Feng, vice president of Air Products China and general manager of the Eastern Region, said in an interview with the media that by 2050, new energy vehicles such as fuel cells will account for more than 90% of the entire automobile industry, and traditional energy vehicles will gradually be replaced. Among them, fuel cell vehicles will account for 17-20%.

　　Not just limited to electric cars

　　In May this year, the Prime Minister visited Toyota's Hokkaido production line of hydrogen fuel cell vehicles in Japan, which sparked a heated discussion about hydrogen fuel cells in the country, and the industry also rethought the overall development of my country's new energy vehicle industry.

　　China's electric vehicle industry is currently booming, and China has become the world's largest new energy vehicle market. Xu Changming, deputy director of the National Information Center, said that from a resource perspective, it is risky for the country to bet all the huge new energy vehicle market on pure electric vehicles. "The development of new energy vehicles in my country should not be narrowly focused on pure electric vehicles, but should have diversified choices."

　　Recently, China FAW's first Hongqi independent fuel cell engine was successfully ignited in Jiaxing, Zhejiang. It is the first domestic 50kW fuel cell engine for passenger cars. This marks that the first step of the three-step strategy of China FAW Fuel Cell's "Hydrogen Win Plan" has been successfully realized, indicating that Chinese companies are paying increasing attention to the fuel cell industry.

　　Japan’s “Hydrogen Energy Society”

　　Globally, Japan is the most enthusiastic about hydrogen fuel cells. In 2017, the Japanese government issued the "Basic Strategy for Hydrogen Energy", proposing to realize the commercialization of hydrogen fuel power generation by 2030, and to fully popularize fuel cell vehicles by 2050, while the sale of fuel vehicles will be completely discontinued. This is Japan’s ambitious “hydrogen society” national strategy. Japan has built 92 hydrogen refueling stations so far.

　　At present, Japan's Toyota has mass-produced the Mirai, a hydrogen battery car with superior performance, and Honda has also launched the Clarity, which can be refilled with hydrogen in three minutes and has a range of 750 kilometers. In addition to Toyota and Honda researching hydrogen fuel cell vehicles, Nissan Leaf is also very interested in hydrogen fuel cell vehicles. In 2017, the above three car companies have officially joined forces to establish a hydrogenation alliance to promote the promotion and development of hydrogen fuel electric vehicles. universal. In March 2018, Toyota united 11 companies to establish the Japan Hydrogen Refueling Station Network Company, hoping to form a standard system for the production of hydrogen fuel cell vehicles in the future through everyone's efforts.

　　In addition to Japan, South Korea also strongly promotes hydrogen fuel cells. Hyundai Motor has begun the research and development and layout of hydrogen fuel cell vehicles as early as 1998. Hyundai Motor is the first automobile company in the world to achieve mass production of hydrogen fuel cell vehicles. They will also Fuel cell vehicles are regarded as the ultimate trend of new energy vehicles. In addition, European and American car companies such as BMW are also actively conducting research on hydrogen fuel cell vehicles.

　　Industrial planning for 1 million vehicles

　　In fact, our country has incorporated hydrogen energy into China's energy strategy. Hydrogen energy and fuel cell technology have been included in the government's "13th Five-Year National Science and Technology Innovation Plan" and have become disruptive technologies that lead industrial change. According to my country's "National Fuel Cell Development Roadmap", the scale of China's fuel cell vehicles will reach 5,000, 50,000 and 1 million in 2020, 2025 and 2030 respectively.

　　Some local governments in my country attach great importance to the development of hydrogen fuel cell vehicles. In June this year, Guangdong Province issued the "Opinions on Accelerating the Innovation and Development of the New Energy Vehicle Industry", proposing to increase subsidies for hydrogen fuel cell vehicles. From 2018 to 2020, 30% of the provincial fiscal subsidy funds will be allocated to the promotion and application of new energy vehicles. It will be used to support the promotion and application of hydrogen fuel cell vehicles. Prior to this, Shanghai, Jiangsu, Hubei and other places had also introduced relevant policies to support the development of hydrogen fuel cell vehicles.

　　Public data shows that as of the end of last year, there were more than a thousand hydrogen fuel cell vehicles in my country, with a significant growth rate, mainly in the field of logistics vehicles. In the next 10 years, fuel cell vehicles will mainly be used in small and medium-sized logistics vehicles and public transportation systems. Zhang Jinhua, executive vice president and secretary-general of the Society of Automotive Engineers of China, said that in the future for a long time, three new energy technology routes, pure electric, plug-in and fuel cells, will play a role in different fields.

　　The challenges are greater than 18650 battery 3500mah lithium

　　Although hydrogen fuel cell vehicles have many advantages, they face huge challenges and obstacles in terms of industrial development and technology. Since the development of my country's hydrogen energy industry started relatively late, industry insiders said that policies, regulations and technical standards still need to be improved, the certification and supervision system is not yet complete, and technology and equipment need to be broken through. Therefore, overall, my country's hydrogen energy industry is still in development. At the initial stage, there is a large gap between the world's advanced levels.

　　Just like the problems faced by high-energy-density lithium battery cars, how to ensure safety is very critical. During the operation of hydrogen fuel cell vehicles, the stability and safety of the stable flow of hydrogen converted into electricity must be ensured. Industry insiders pointed out that for hydrogen fuel cell vehicles to enter the market, safety issues must be solved, otherwise it will cause great harm to the industry.
