Which is better for ternary lithium battery pack and hydrogen fuel power battery?

Advantages of the ternary lithium battery pack 1. High energy density of the battery: The energy density of the battery is the electric energy released by the uniform unit volume or mass of the battery. The greater the energy density of the battery, the more electricity stored in the unit volume; 2. High electricity: The battery has a higher energy density, and the same battery volume can hold more electricity. The battery capacity has reached 53.6kWh, and one minute of electricity, one minute of battery life, which lays the foundation for long battery life; 3. High tap density: The tap density refers to the measurement of the powder in the container after being tapped under specified conditions. Get the mass per unit volume. Tap density or bulk density means the mass of the sample divided by its volume. This volume includes the sample itself, the sample pores and the sample gap volume. Disadvantages: poor safety, poor high temperature resistance, poor life, poor high-power discharge. Poor safety and short cycle life are important shortcomings of ternary lithium battery packs, especially safety performance, which has been an important factor that has restricted its large-scale configuration and large-scale integrated use. Advantages of hydrogen fuel power cells 1. Compared with traditional fossil fuels, hydrogen fuel power cells use electrochemical reactions. When supplying energy, only water and heat will appear. Traditional fossil fuels will produce various toxic and harmful gases and dusts, which is a great tool for environmental sanitation. 2. Compared with other traditional batteries, hydrogen fuel power battery is a kind of power generation device, and the traditional battery only has the function of storing electric energy. Hydrogen fuel electromagnetism is the same as a generator, which directly converts chemical energy into electrical energy, which is much better than traditional batteries in terms of convenience. 3. The energy conversion rate of hydrogen fuel power cells is high. Generally, the energy conversion caused by combustion is only over 30%, while the energy conversion rate of hydrogen fuel power cells has reached an astonishing 80%. Using fewer resources to get more energy, it must be a more cost-effective hydrogen fuel cell. Disadvantages 1. The safety of hydrogen; although hydrogen is favored by the public as a new energy source in the future, the safety of hydrogen is worthy of attention, although various studies have stated that the safety factor of hydrogen is higher than that of gasoline. However, there are still many people who think that the hydrogen cylinder is a hydrogen bomb, so the promotion of hydrogen fuel still needs vigorous publicity. 2. There are not many sources of hydrogen: because the earth's air does not contain a lot of hydrogen, although hydrogen can be obtained by electrolysis of water, it is not a very economical way to generate hydrogen at the expense of electricity. Of course, if the industry is scaled up, costs will naturally fall, and there is still a long way to go. 3. High threshold for hydrogen fuel power battery technology: my country’s economy has developed rapidly in recent years, but many high-tech industries are still very weak, and hydrogen fuel power batteries require absolutely no investment. Therefore, my country’s hydrogen fuel power battery sector, There has not been any substantial progress yet, and great investment is needed to reap the rewards. In my country, the biggest advantage of ternary lithium battery packs is that the output has been greatly developed under the encouragement of national policies in recent years. It can be said that Chinese companies have mastered its core technology and have become the largest in the world. The cost of lithium battery processing countries has been greatly reduced, and a large-scale industry has been fully formed. The hydrogen fuel power battery technology, whether it is the process formula of the reactor catalyst or the core technology of the gas storage tank, my country has not formed a large-scale industry, so the cost is extremely high. However, our country has the industrial conditions to develop hydrogen energy. Every year, the hydrogen by-products in the domestic petrochemical industry are sufficient for vehicle use. The cost of obtaining hydrogen is relatively low, and do not rely on the high energy consumption method of electrolysis of water to obtain hydrogen. The large-scale development of fuel cell vehicles has laid a good foundation. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
