Can hydrogen power become an alternative to solid-state batteries?

Can hydrogen fuel-powered batteries go down to the altar, and can lithium batteries go into the home? Recently, there have been reports that in 2019, hydrogen fuel-powered battery vehicles are expected to officially implement the 10,000 vehicle plan in 10 cities, and first-tier cities such as Beijing and Shanghai are expected It is listed as a city to be launched soon. With the increasing popularity of hydrogen fuel power batteries and the introduction of relevant national incentive policies, can hydrogen power become another technical route besides solid batteries? In fact, many automotive industry insiders claim that there are no new cars at this stage. At the same time, the mining of ternary lithium battery materials will cause environmental pollution. From the power structure, thermal power plants still occupy most of the electricity, and the recovery of discarded batteries after deceased new cars will also be the effect on the environment. Therefore, many people said that the new power car at this stage is not a new power. From the perspective of mass-produced hydrogen-powered vehicles, its comprehensive endurance is between 600-700 kilometers, the energy conversion rate is as high as 60-80%, and the emission is only pollution-free water, which has the advantages of short refueling time and light weight. Therefore, some people say that hydrogen is the ultimate clean energy for human society. Since the new domestic subsidy policy was born in 2018, it is now the hydrogen fuel power battery as a subsidy. Obviously, the car company is still the policy guide, whether it is unwilling, there are too many other competitors behind it, a new journey from the shopping mall , The research and development of domestic hydrogen fuel power cells has always been a breakthrough, and large-scale processing has been close at hand. Recently, my country has developed a new type of catalyst for the Hydrogen Fuel Power Battery University of Science and Technology to deal with the carbon monoxide poisoning shock crisis of hydrogen fuel power batteries, extend battery life, greatly expand the ambient temperature of battery use, and will compensate for the impact of ambient temperature on solid energy batteries. , North Korea is a very good message. Since hydrogen has so many advantages, why do solid energy batteries lose their advantages? Can hydrogen batteries be charged quickly? Want to know this question, we will source from hydrogen fuel-powered batteries, hydrogen fuel-powered electric vehicles (FCEV) actually as early as 1893 In the long-term development of the technical method proposed in the year, due to its price and material problems, the hydrogen fuel power cell has not been able to be processed on a large scale. Until 2015, Toyota launched the first processing mode Mirai, thus opening up the method of storing hydrogen. Many people think that hydrogen fuel power cells are difficult to commercialize due to cost issues, especially the platinum element used in fuel power cells. However, from the perspective of fuel power cell utilization, the platinum content used in a 100kW fuel power cell system is 41.67g. According to the calculation of 500 yuan/gram, the capital is about 20,833 yuan. About 500,000 yuan of fuel-powered cell vehicles, catalysts and proton communication membranes are not the key to preventing commercialization. Through inquiries, we found that the key to restricting the expansion of hydrogen fuel cell vehicles is the delivery of hydrogen. Hydrogen does not appear through electrolysis as we imagined, but through the by-products of petroleum, coal, ethylene and other materials, and the cost is very low. Sinopec’s data flashed by. Its annual production of hydrogen is 2 to 3 million tons, and the cost is 20 to 30 yuan/ton. Think about 6-7 kilograms of gasoline for a hydrogen fuel-powered battery car, and a mileage of 600-700 kilometers. The cost advantage is extremely amazing. However, due to the origin of distance and application problems, hydrogen transportation has become a big problem. Hydrogen has a very special phenomenon hydrogen embrittlement. When the pressure exceeds the pressure and temperature, hydrogen will escape into the metal and form embrittlement of the metal material. Therefore, it cannot be used for general cylinder transportation. In addition, the construction cost of hydrogen refueling stations is high, which in turn increases the price of hydrogen. From the perspective of Toyota Mirai gas charging cost, its price is about 39 yuan/kg, of which hydrogen cost accounts for about 45%, distribution cost accounts for more than 20%, and Tesla models consume about 16 yuan for 100 kilometers of 20kwh. The high transportation cost of hydrogen has become an obstacle to the development of hydrogen fuel power cells. The bottleneck of solid energy batteries Compared with hydrogen fuel power batteries, lithium batteries are already very mature in terms of materials and industrial chain, and due to mass production, the cost advantages are obvious. In addition, the technical difficulty is relatively small. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
