Automotive Energy Wars: Lithium Battery vs Hydrogen Energy

With the increasing awareness of human beings to protect the environment, fuel vehicles have become something that people love and hate, and they are loved because cars meet our travel needs and spiritual comfort. At the talk show conference, there were guests who ridiculed: the car is like another home for men, after parking, they like to stay in it for 5 minutes, after all, only in this moment, they can be themselves, other times can only be fathers, sons or grandchildren; hate them because the car burns oil more money: parking, insurance, maintenance, tickets, and rising oil prices, all need money, open a car, as if opening a channel to the society to "send money". Now, fuel vehicles need to abide by a lot of rules, often encounter single and double number restrictions, everyone always feels that it costs hundreds of thousands, only buy back "half a car", dumb to eat huanglian. Moreover, the mainstream media often publish articles claiming that car fuel is one of the main causes of urban smog, and it is recommended that everyone travel green.

In the face of such a suffocating car life, there are still people who buy cars one after another, poor, rich, working people, artists, CEOs, etc., as if everyone needs a car. Cars represent identity, and without cars there is no way to fit into a certain circle. There is a huge contradiction between strong demand and tightened policies, and the way to solve such a contradiction is to adopt new technologies and new energy new energy concept cars.

Electric cars, it is not easy to say that I love you

According to the general direction of the current policy, electric vehicles have a tendency to replace fuel vehicles, such as electric vehicles are not limited to the number of policies, and for example, some cities buy 300,000 electric vehicles, there are 120,000 subsidies, some public transportation, such as taxis, Didi taxis are more respected electric vehicles. In addition, Tesla has set off a boom in electric vehicles around the world, and Musk often wins titles such as the world's richest man, making the aesthetics of electric vehicles very high. Unfortunately, as the core component of electric vehicles, the development of power batteries has been very slow, and in the past two years, there has been almost no progress. And affected by the epidemic, the raw materials and manufacturing costs of lithium batteries have risen sharply, and battery suppliers such as Ningde Times, although they have massive orders, cannot be delivered due to insufficient production capacity. In this case, there is no energy to develop new battery technologies, so that the electric vehicle power battery has a short endurance, cold and cold characteristics, it is difficult to change.

I believe that the northeast driver for the petite electric vehicle, feel quite deeply, after all, the battery in the cold weather "power loss" is very serious, which also led to the electric vehicle outside the Shanhaiguan "inch difficult to move". Relevant data show that the proportion of national automobile sales, fuel vehicles are still as high as 92.8%, electric vehicles are only 2.8%, only a fraction, and only 2.8% are mostly distributed in Jiangsu, Zhejiang, Shanghai, pearl river delta region. If someone sees a Tesla in the northeast county, they will definitely feel: the family has money to burn bags and run over to take a group photo.

In fact, the nationwide electric driving experience is not good, and in the northeast region or north China in winter, the electric vehicle experience is very poor, which can be described as "trembling and fearful". A northeast driver cried that the endurance of his electric vehicle is 400 kilometers, but once the temperature drops to 5 to 10 ° C, the endurance will drop to 200 kilometers, plus the cold needs to open the warm air, occasionally open the high beam etc. Roughly calculated, you need to charge 3 times a week, 5 hours each time, waiting for an electric car is the same as waiting for your father. Behind such complaints is the bottleneck of battery technology, the phenomenon of power loss is a chemical problem, in the low temperature environment, the diffusion of lithium ions, the movement of surface charge will be affected, reducing the battery power density. Based on this, there are only two directions to solve this problem: the first is to innovate the diaphragm and shell technology to protect the electrolyte from being affected, and the other is to upgrade the electrolyte material to increase the endurance. To be fair, both directions are quite difficult, and it is no wonder that some people say: whoever can solve the battery problem is the new world's richest man.

When will hydrogen vehicles leave the lab?

If the power battery is destined to be delicate, then to change the future of human vehicles, you can only upgrade new energy again. Hydrogen energy seems to have been put on the agenda, replacing batteries and fuel, while controllable nuclear energy is still in the "concept stage", a bit of science fiction, but Nothing is impossible. These include tempered shells with unconventional hardness, flying cars, and hydrogen and controllable nuclear vehicles.

In fact, according to the characteristics of hydrogen energy, it is easy to attract the attention of capital, policies, and management strategies, after all, it is too clean. The early concept of hydrogen energy electric vehicles is to generate kinetic energy through the combustion of hydrogen internal combustion engines, and the power mechanism is similar to that of fuel vehicles. However, compared with fuel oil, the stability of hydrogen combustion and the efficiency of power conversion are very poor, and it is difficult to land. Now, the power source of hydrogen energy vehicles is mainly through the chemical reaction of hydrogen fuel in the battery stack, converting chemical energy into electrical energy. The advantage of hydrogen energy over lithium batteries is that it has a high power density and can be applied to long-distance transportation, including trucks, buses, materials, heavy trucks, etc., and hydrogen energy batteries can be used. In addition, hydrogen energy is of great significance to environmental protection, and all sectors of society are full of confidence. Relevant institutions predict that the number of hydrogen energy vehicles in the country will exceed 100,000 by 2025; in 2035, 1 million, which means that the future hydrogen energy vehicle market size will grow 10 times.

Of course, like all new energy sources, hydrogen energy also faces problems in terms of cost, technology, and energy replenishment. Take "replenishment" as an example, the future hydrogen energy supply scene is similar to that of gas stations, and it takes only 6 minutes to add hydrogen energy, which is much better than the 5-hour charging of electric vehicles. However, a large number of hydrogen energy supply stations need to be built, and there are only 110 available supply stations in the country, which is basically negligible; plus the cost of "hydrogen production", which is also relatively expensive, roughly calculated, the construction cost of a hydrogen energy station is three times that of ordinary gas stations. Perhaps, in the future new energy vehicle war, hydrogen energy will replace lithium batteries, but the time is relatively long, waiting for the flowers to bloom!
