Briefly analyze the performance comparison of lithium battery and hydrogen fuel power battery

Performance comparison of lithium and hydrogen fuel power batteries. In this field, lithium battery electric vehicles are well-deserved protagonists, but frequent accidents often make people sweat. At the same time, the future of increasingly radical hydrogen fuel is uncertain. It remains to be seen whether lithium batteries or hydrogen fuel can carry this banner and help new energy become a wind energy port. Performance comparison of lithium and hydrogen fuel power batteries From a technical point of view, hydrogen fuel power batteries are much better than power lithium-ion batteries. For example, the filling time of a hydrogen fuel power battery is 3 minutes, 5 minutes, and the roof is extended by 10 minutes and 20 minutes. Heavy-duty trucks with a mileage of up to 300 kilometers, 500 kilometers, 700 kilometers, or even 1,000 kilometers and 2,000 kilometers are fine, but pure electric vehicles cannot. In addition, the use of hydrogen fuel power battery is pollution-free, even if it is pollution-free after disassembly, the disassembly of the battery causes pollution. Hydrogen fuel power battery has high energy storage density, light weight and long cruising range. Usually more than 500 kilometers, but according to the battery capacity of pure electric vehicles, the current mileage of most pure electric vehicles is about 300 kilometers, and a few models can reach 400 to 500 kilometers. From the technical difficulty and cost of both parties, the technical difficulty of lithium batteries is relatively small, and the processing is relatively mature. At the same time, the entire manufacturing industry chain is perfect. In the stage of expanding the scale effect, and the key hydrogen fuel power battery proton exchange membrane Materials, catalysts, and double plates are in a blank state, and the basic domestic industrial chain and manufacturing costs and the construction costs of gas stations, etc. The fuel power battery is different from the traditional lithium battery, it can be filled with fuel quickly in 3-5 minutes, and the battery life is longer. For traditional new energy vehicle charging, this has become a luxury. Lithium batteries and hydrogen fuel power batteries are equally powerful, each has its advantages and disadvantages. Lithium batteries are inexpensive and more commercially mature, so they have become a natural choice for electric vehicle manufacturers. However, its low energy density, flammability, toxic reaction products, and slow charging speed are also potential hidden dangers, especially after mass production, various problems will naturally magnify. To sum up, as the power source of automobiles, hydrogen fuel power battery has the advantages of high energy density, long cruising range, short charging time, light weight, and large performance improvement space compared with lithium batteries. Tsinghua University professor Ouyang Minggao said that the most likely relationship between hydrogen fuel power batteries and lithium batteries in the future is coexistence. The characteristics of hydrogen fuel power battery do not pollute the hydrogen fuel power battery does not pollute the environment. It is through electrochemical reaction, not through combustion (gasoline, diesel) or energy storage (battery). If hydrogen is produced by renewable energy sources (photovoltaic panels, wind energy, etc.), then the entire cycle is a complete process and no harmful emissions will occur. No noise The fuel-powered battery is very quiet, and the noise is about 55 decibels, which is equivalent to the volume of a normal conversation. This makes the fuel power battery suitable for indoor installation, or in places with limited outdoor noise. High efficiency The power generation efficiency of fuel power cells can reach more than 50%, depending on the conversion properties of fuel power cells. Chemical energy is directly converted into electrical energy, without intermediate conversion between thermal energy and mechanical energy (generator). There are many battery technologies, but lithium is the largest market share. In the competition between hydrogen fuel-powered battery vehicles and lithium battery vehicles, lithium battery pure electric vehicles currently have advantages. The biggest disadvantage of hydrogen fuel cell vehicles is the high manufacturing cost. Therefore, it is too early to tell who will win and who will lose. After all, battery technology and design are changing with each passing day, and one of them will eventually occupy the top spot.
