Electric vehicle power lithium ion battery fuel power battery and lithium battery comparison

Fuel power cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as electrochemical generator. It is the fourth power generation technology after hydropower, thermal power generation and nuclear power generation. Lithium batteries are a kind of secondary batteries that rely on lithium ions to move between the positive and negative electrodes to work. During charge and discharge, Li+ intercalates and deintercalates back and forth between the two electrodes: Li+ is deintercalated from the positive electrode during charging, and inserted into the negative electrode through the electrolyte, the negative electrode is in a lithium-rich state; the opposite is true during discharge. Battery.jpg The biggest difference between hydrogen fuel power battery and lithium battery is that it does not need to be recharged, only needs to be hydrogenated, and it is very convenient to use similar to ordinary fuel vehicles. Although the price is close to the people, fuel-power battery vehicles started later than lithium battery electric vehicles, and their industrial chain is longer than lithium battery electric vehicles. The industry chain of lithium battery electric vehicles has basically been opened up, and fuel power batteries have not yet been perfected in China. The industrial chain is formed. Comparison of fuel-powered batteries and lithium batteries 1. From the perspective of consumers, fuel-powered battery vehicles have a long cruising range, fast hydrogenation, and have better driving experience than electric vehicles, which undoubtedly can bring better user experience. Although the development of fuel-powered battery vehicles has been slow, they have not lost market enthusiasm. The establishment of fuel-powered battery vehicle hydrogen refueling stations, the localization of key components, and technological advancement to reduce processing costs are far more innovative than lithium batteries that have fallen into the bottleneck of new energy density and increased mileage. 2. Regardless of whether fuel power batteries or lithium battery related technologies, there is still a lot of room for improvement. If the cost of fuel power batteries can be reduced, it can truly be used as an alternative energy source for gasoline/diesel fuel. As for the lithium battery, if its energy density can be further improved and the cycle life can be longer, it is also a very good driving energy source. 3. The major obstacles to the development of fuel power batteries are the high cost and the complicated hydrogen production process. The entire hydrogen refueling and hydrogen supply network must be built from scratch. Hydrogen is obtained by electrolysis or steam reformation. However, the cost of these two methods is quite high, and the cost required to produce the same quality of natural gas is 1/2 or even 1/3 of that of hydrogen production. The processing cost of lithium batteries is relatively low. In addition, it is very convenient to recharge and use. Compared with other portable energy sources, it is more cost-effective. 4. Fuel power batteries and lithium batteries have little impact on the environment. The former combustion product is water that does not produce greenhouse gases generated after gasoline/diesel combustion; the discharge products of lithium batteries may be lithium oxide, lithium hydroxide, etc., and will not affect the environment. In addition, lithium batteries can be reused. Based on the above points, these two types of batteries have become the most popular power sources for electric vehicles.
