Power Battery: Who is the rising star of new energy cars?

In recent years, new energy vehicles seem to have been dormant for many years. The actors waiting for an opportunity to appear have burst overnight. However, many people think that new energy vehicles and fuel trucks are small fresh meat levels. In fact, it is also counted as the "old bacon" of the same age as the fuel truck. The earliest electric cars in the world were born earlier than the internal combustion engine cars. In 1873, the British Robert Davis made the world's first utility electric car. However, for various reasons, the fuel car replaced the electric car. The mainstream, but fortune, we will have to turn back soon.

At present, the world's new energy vehicles are divided into a variety of, mainly: pure electricity, hybrid, new fuel vehicles.

Although the current stage of mixing is a relatively popular new energy vehicle, if you want to completely get rid of fuel, then in the final form of the development of new energy vehicles in the future, hybrid models will be gradually eliminated, pure trams and new fuel vehicles will be the upper position.

However, individuals believe that the most promising future is new fuels because new fuels have relatively few shackles.

At present, pure electric vehicles can be divided into several factions, such as pure electric vehicles equipped with battery Motors. Companies such as BYD are quite accomplished in lithium batteries and are not subject to technical restrictions on new energy vehicles such as batteries, motors, and electronic controls. Therefore, its development prospects are better than those of other technology-constrained car companies. Even Tesla, which was once favored by the industry, has reached a very dangerous point because it does not have the ability to produce batteries independently. As a car, it is mainly a lithium-ion battery. This battery can be recycled. This rechargeable battery was born around 1996. Safety, capacity, and price have all risen by one grade.

There are also car companies specializing in hydrogen fuel, such as Toyota, Honda, and Hyundai. Toyota's Mirai, Honda's Clarity FuelCell, and modern Nexo, hydrogen fuels have a shorter refueling time than pure electric vehicles, so they also have a longer endurance, and their energy conversion efficiency can reach 60%, and will not produce Any pollutant can achieve true zero emissions, but hydrogen fuel also has a lot of flaws. For example, to store hydrogen fuel is a very technical test. I believe that when you look at the chemical element table in junior high school, you know, Hydrogen is in the first place. It has only one electron inside. Therefore, the volume of hydrogen atoms is very small. Even in dense containers, hydrogen atoms are easily escaped, and the stability of hydrogen atoms is poor. It is very easy to be dangerous.

At present, the technology of hydrogen atoms is relatively immature, resulting in an increase in its cost. In addition, the infrastructure is not perfect, so the research on hydrogen fuel is still a long way to go. Similarly, methanol fuel is relatively good, but methanol fuel is relatively good because it is cheap and also does not produce pollutants, but its energy density is smaller, and the mileage of methanol vehicles is shorter than that of gasoline of the same volume. It is corrosive to metals. Vehicles using methanol fuel require specially modified engines. However, methanol has now been listed as an alternative fuel for future automotive development. Without leaving aside infrastructure such as the refueling station, the prospects are still very impressive. At present, Geely has made considerable achievements in the study of methanol cars and has launched a methanol-powered car.

Of course, one of the most amazing things about the industry: graphene batteries. Here we have to mention the right way group, for graphene batteries, they are very persistent. At this year's Beijing Motor Show, Seiji Group took its H500, K350, and HKGT vehicles to the public. They prefer to use their own fuel to charge batteries through the generator Extender. The endurance of these vehicles will reach or exceed 1,000 km. The graphene battery that has been working tirelessly for the right path can also achieve a comprehensive endurance of 1000km. And it has the advantages of a long life of core components and 100 programs.

Graphene batteries can compress charging time to the extreme because lithium ions can travel quickly and heavily between graphene surfaces and electrodes, but it has to be said that graphene costs are really high, and if they can be mass-produced in the future, the cost reduction is naturally excellent. But it takes a lot of time to solve.
