Solid-state lithium battery and hydrogen fuel power battery, who is the mainstream of new energy vehicles?

Solid lithium battery and hydrogen fuel power battery, who is the mainstream of new energy vehicles? At present, solid lithium battery and hydrogen fuel power battery technology has become an important technological journey of the new power vehicle industry. The two vehicles compete for the first place, each with their pros and cons. Where does my country’s new energy vehicle layout go? Hydrogen Cloud Chain believes that solid lithium battery technology is relatively mature and will have a commercial basis; hydrogen fuel-powered batteries are expected to become the first to replace fuel under long-distance and heavy loads Batteries for powered cars. Details: ●The lithium battery industry has a solid foundation, but solid battery skills need to be improved. Solid lithium battery technology is an important way to break through the energy density of automotive power lithium-ion batteries. Solid-state batteries have advanced advantages such as high ionic conductivity, high mechanical strength, and energy density. Thanks to the original technology and industrial resources of domestic lithium batteries, they can end mass processing and low cost. Solid-state batteries have great potential and energy density in terms of safety, but a lot of research work has to be done to improve the electrode/electrolyte interface, solid electrolyte treatment, and chemical stability to make up for the reduced journey, difficulty in charging, and high energy efficiency. The control system is at low temperature. ●Hydrogen fuel power battery has obvious functional advantages, but lacks core technology and insufficient supporting processing. Hydrogen fuel power battery is another branch of the industry. Hydrogen fuel power batteries have the characteristics of light weight, long life, high energy density, short charging time, long battery life, and environmental protection. However, its key components such as proton communication membranes, catalysts, bipolar plates and other core technologies have been monopolized by foreign countries for a long time, which has severely restricted the development of the industry. In addition, my country has not yet formed a complete hydrogen energy ecological chain for hydrogen processing, storage and hydrogenation, and it lacks hydrogen energy-based equipment processing, which makes it difficult to promote on a large scale in a short time. ●The application advantages of the two dynamic technologies are different. The open environment of domestic new power vehicles is messy and the needs are different. The journey of solid lithium battery and hydrogen fuel power battery has its advantages and disadvantages, and faces each potential practical application. Both types of skill travel have their uses in terms of dynamic distribution, climate, geography, and regional functional differences. First, the distribution of coal resources in my country is uneven. Nearly 50% of coal resources are located in North China, and about 30% of reserves are located in Northwest China, while coal resources in East China and Southwest China are relatively scarce. The remaining capacity of power plants in North China and Northwest China can be used to supply power to solid lithium battery vehicles through charging piles, thereby achieving the dual effects of fuel substitution and improved power utilization. According to statistics, my country's average wind curtailment rate in 2018 was 7%, mainly concentrated in Xinjiang, Gansu, Tibet and other regions. With the opening of hydrogen production technology, these unused resources can be converted into hydrogen and stored by means of compressed gaseous hydrogen storage and liquefied hydrogen storage. Therefore, abundant local renewable energy provides favorable conditions for the start-up of hydrogen fuel-powered battery vehicles. Secondly, the existing solid-state battery technology cannot meet the application needs of the northeast and other high-cold regions, and hydrogen fuel power batteries can be used as an alternative technology in these regions. Third, from the perspective of geographical conditions, the distribution of cities in East China is relatively concentrated, the opening speed is relatively fast, the number of vehicles continues to rise, and the nearby traffic lines are full, suitable for driving solid lithium battery vehicles. In addition, it is relatively easy for hydrogen refueling stations in the port to assemble and deploy the hydrogen industry in the port. Expressways and other service areas along the route are also convenient for the construction of oil-hydrogen mixing stations, creating inter-city high-speed hydrogen energy, and ending the integrated layout of hydrogen filling stations and charging stations.
