Explain which of lithium-ion batteries and hydrogen fuel cells is more promising?

Recently, the Beijing Municipal Bureau of Economy and Information Technology plans to cultivate 3-5 leading enterprises in the hydrogen fuel cell vehicle industry chain with international influence by 2023, and strive to promote 3,000 hydrogen fuel cell vehicles. The total hydrogen fuel cell vehicle industry chain has accumulated The output value broke through 8.5 billion yuan. Since 2020, despite the impact of the new crown epidemic and the uncertainty of the national subsidy policy of the hydrogen energy industry, the overall development speed of the hydrogen energy industry has slowed down, but the investment has shown a trend of upward trend, indicating that my country's industry The heat is still there, and the market still has greater confidence in the development of hydrogen energy. After the official introduction of the national subsidy policy for hydrogen energy, there is still room for growth in the amount of investment in the hydrogen energy industry in the fourth quarter of 2020. Lithium-ion batteries and hydrogen fuel cells each have their own merits and promises. Lithium-ion battery technology is relatively mature, and the current main power source and technological development of new energy vehicles. Ternary lithium, lithium iron carbonate, nickel metal hydride, and lithium hydroxide, from the research and development of materials and continuous breakthroughs, technology updates. Step by step, we are improving the power performance of lithium-ion batteries and the continued mileage has been improving. The advantages are simple and cheap, high safety performance, and large-scale processing to reduce costs. At present, the price of new energy vehicles based on lithium batteries has been reduced to comparable to that of fuel vehicles, which is cost-effective. It is environmentally friendly when driving and will not cause secondary air pollution such as exhaust emissions to the surrounding environment. However, the disadvantages of lithium-ion batteries are also very prominent, and battery technology needs to be broken. It has short voyage mileage and long charging time, suitable for short-to-medium-distance driving under 800 kilometers. It can be replaced by passenger cars on the model, and the power of large trucks is clearly insufficient. At present, the most representative hydrogen fuel cell vehicle is Toyota's MIRAI, which has a range of more than 500 kilometers. It can also serve as a mobile power station and a trunk socket, which is enough for a week of electricity for an average family. Two major drawbacks, one is that hydrogen is stored at a pressure of 700 atmospheres, and the consequences of a leak or explosion are unimaginable. Furthermore, there are too few hydrogen refueling stations and there is nowhere to refuel. The use of platinum as a catalyst is not a big problem. One is that the amount is small, and the other is that there are substitutes. In addition, hydrogen fuel cell technology is still in its infancy, and it has not yet undergone large-scale processing and commercialization. Technology also needs to be improved and developed. In short, hydrogen and lithium-ion batteries can complement each other. At present, it seems that they have not reached the point of perfection. So both have a future. The commercialization of lithium batteries goes faster. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
