Fuel power cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as electrochemical generator. In terms of power technology, it is the fourth power generation technology after hydropower engineering, energy and nuclear power. Lithium battery is a kind of secondary battery. The key to its work is to move the lithium ion battery between positive and negative. Li+ is inserted and released back and forth between the two levels during the whole process of battery charging: Li+ is released from the positive stage when the battery is charged, and placed in the negative stage according to the lithium battery electrolyte. The negative stage is rich in lithium; it is charged and discharged The time is reversed.
The biggest difference between a hydrogen fuel power battery and a lithium-ion battery is that it does not need to be charged, but only needs to be hydrocracked. It is similar in application habit to a normal fuel car, and it is very convenient to apply. Although the development is relatively late, compared with lithium battery pure electric vehicles, its price is parity, and its whole industry chain is longer than lithium battery pure electric vehicles. The whole industry chain of lithium battery pure electric vehicles has been basically connected, and China still expects power The entire industry chain of lithium batteries has not been produced.
The difference between fuel power battery and lithium ion battery
1. From the perspective of customers, solid-state battery cars have long mileage, faster hydrocracking speed, and feel safer to drive better than pure electric cars. There is no doubt that they can produce a stronger customer experience. Therefore, the Although the development trend is slow, it has not lost the attention of the sales market. Compared with lithium batteries, which are deeply involved in the shortcomings of new specific energy to increase mileage, the creation of lithium-ion battery hydrogen energy vehicles, the domestic production of important parts, technical developments have reduced product costs, and the topic of independent innovation.
2. Whether it is a natural material power lithium battery or a lithium battery-related technology, there is a very large development trend. Indoor space, if the cost of the natural material power lithium battery can be reduced, it can be truly turned into a gasoline/diesel engine fuel for vehicles. To replace electric energy. For lithium batteries, if its specific energy can be further improved and the service life of the circulatory system can be increased, then it is also a very good electric energy driver.
3. The key obstacles to the development trend of fuel power cells depend on the increase in cost and the complicated processing technology for hydrogen production from electrolysis of water, and the Internet for all radon gas supply supporting facilities needs to be created from the ground up. Hydrogen is obtained according to the electrolysis method or steam asset reorganization. Even so, these two methods are very expensive, and the production of gas of the same quality requires 1/2 or even 1/3 of the cost of hydrogen production from electrolysis of water. The product cost of lithium battery is relatively low, and its rechargeable battery is also very convenient. Compared with other portable power sources, it has a higher cost performance.
Fourth, fuel power batteries and lithium batteries have very little harm to the natural environment. The first kind of igniting substance is water, which is not easy to cause air pollutants caused by car gasoline/diesel engine ignition; the charging and discharging substance of lithium batteries can be lithium metal oxide or nickel hydroxide, which is not harmful to the natural environment. And lithium batteries can be used in cyclic systems. On this basis, these two types of rechargeable batteries have become the most fashionable power lithium battery types for battery cars at this stage.
