In the era when automobiles have brought a lot of convenience to people's lives, many people are inseparable from cars for daily travel.
Because the car is fast to drive, there are many more practical features, such as air conditioning, which can make people less cold in the cold season and less hot in the hot summer.
Just when everyone thought that driving a car had to be refueled, the development of new energy vehicles was particularly rapid, so that everyone knew that pure electric vehicles could be used.
This is because oil, as a non-renewable resource, is still able to meet daily needs, but its price is very high and is expected to rise in the future.
In order to avoid the daily expenses required by people to refuel every day, they have also entered an era of new energy vehicles, and many people will choose pure electric vehicles or plug-in hybrid models.
Of course, the pure electric vehicles can be used only by charging them every day, which is not only environmentally friendly but also meets the needs of ordinary cars.
The plug-in hybrid model, which can be plugged in and use fuel, is also the first choice for many people when buying a car.
Whether you choose a pure electric vehicle or a plug-in hybrid model, the battery is an essential part of the car.
The quality of the battery directly affects the mileage and service life of the car, so it is an accessory that many people pay more attention to when buying a car.
According to the announcement of a Chinese company, it is particularly shocking that there is a major breakthrough in all-solid-state batteries, which beats all electric vehicle batteries in the world, let's find out.
1. The significance of solid-state batteries breaking through 720Wh/kg
Everyone is familiar with electric vehicles, but there is very little understanding of the battery of electric vehicles, and only know that the battery of electric vehicles needs to be replaced, and the cost is very high.
The reason why solid-state batteries break through 720Wh/kg is a very explosive news is because among other electric vehicle batteries, if they can reach 360Wh/kg, it is relatively rare.
This data belongs to the energy density of lithium-ion batteries, and the specific data has a lot to do with the battery brand.
For example, the silicon anode battery for automobiles developed by a company in the United States has a high density of 400Wh/kg, but there is no news that it has been applied.
The common lithium-ion battery is only 120Wh/kg-260Wh/kg, and some experts in the professional field are studying the anode lithium metal solid-state battery is difficult to exceed 350Wh/kg.
If you want to say that there are more powerful brands in solid-state batteries, then Toyota and Panasonic are Japan, but their solid-state battery density will not exceed 500Wh/kg.
So when you see a Chinese company producing all-solid-state batteries with a density of 720Wh/kg, it's really incredible.
If there really is such a battery, then it will definitely hang the batteries of all electric vehicles in the world.
Because neither the solid-state batteries that have been marketed nor those that are being studied have achieved such a good energy density.
The successful development of this battery is of great significance, as it shows that up to 720 watt-hours of energy can be stored per kilogram of battery.
It also means that the range of electric vehicles has increased a lot compared to before, because according to the electric vehicle batteries on the market, the density of 200Wh/kg is already very powerful.
Now that it has reached 720, it is almost 4 times more than 200, which will definitely bring a lot of convenience to electric vehicles.
Many car owners have always wanted to buy pure electric vehicles, but they have been afraid to buy them because of the range or anxiety in this regard.
So with today's battery, there is no need to worry, so that you can have no endurance anxiety when you commute daily and even have the need to run at high speed.
This also shows that the development of pure electric vehicles has ushered in a new milestone, and it will not take a few years to replace fuel vehicles.
Second, the strength of the company in research and development
Due to the development of pure electric vehicles, many companies are researching all-solid-state batteries, and in this case, those that can surpass any battery in the world must be more powerful.
It is understood that the company that announced a major breakthrough in all-solid-state batteries was established in 2018, and the company name is Tailan New Energy.
Although it has not been established for a long time, it has received several rounds of investment and was co-founded by a team of experts at the professional level.
This new energy company is mainly engaged in the development and research of lithium batteries, and is headquartered in the capital of the mainland.
The company had already developed a solid-state battery in its second year of existence, and production began four years later.
Through the technical achievements shared by the company on the official account, it can be known that many key technologies have ushered in breakthroughs, such as the integrated molding process of solid-state batteries.
It is very difficult to develop this kind of technology, but the fact that this company can develop it is enough to prove its strength.
In addition, it has a very high technical level in terms of high-capacity advanced cathode and anode materials, so it is normal to be able to develop a battery with a density of 720Wh/kg.
Relevant data show that the newly developed battery not only has a particularly surprising density, but also adopts a lot of good technology, and the performance has been greatly improved.
You must know that when people drive pure electric vehicles, they pay great attention to the range of the battery, and if the range is low, it will make people feel insecure.
There are also many people who dare not buy a car even if they want to choose because of the range of pure electric vehicles.
However, through the newly developed battery of Tailan New Energy Company, I believe that it can be a good way to improve people's problems in this regard and have stable performance.
It can make the battery life longer, but also because the materials used in it make the cycle, stability and density of the battery have been greatly improved.
When using the battery, even if there are multiple charge and discharge cycles, it is not easy to have the problem of degradation, because it improves the performance of the battery and supports a higher rate of charge and discharge.
What the company's CEO said in an interview in August last year shows that at that time they were already very strong in semi-solid-state batteries, with a density of 350Wh/kg~400Wh/kg.
Not only a few months later, a solid-state battery with a density of 720Wh/kg has been developed, which is really unimaginable.
3. Advantages of pure electric vehicles
More and more people are choosing pure electric vehicles when buying a car, also because this type of car has many advantages.
For example, it can achieve zero pollution and zero emission, and compared with ordinary fuel vehicles, there will be no harmful substances released into the atmosphere to pollute the environment.
This is also the reason why the mainland vigorously promotes people to buy pure electric vehicles, which can better improve air quality and protect the environment.
In addition to this advantage, the development of electric vehicles is also relatively fast, and many cars support fast charging, which does not take a long time to meet the needs of daily cars.
In addition, now that the charging pile equipment has been vigorously promoted, charging piles can be seen in many cities, and it is very convenient to use.
When driving on a daily basis, due to the characteristics of pure electric vehicles, the noise generated is relatively low, so you can enjoy a quiet travel experience.
Because the structure of pure electric vehicles is relatively simple, it is easier to repair faults during daily driving, and the cost is less.
If you choose to use electricity at night when charging, the price is relatively low, which can save the cost of using the car.
Fourth, the maintenance method of pure electric vehicles
In the daily use of the car, in addition to the fuel car needs to pay attention to maintenance, pure electric vehicles also need to pay attention.
Because after good maintenance, the car can have a good life, when using pure electric vehicles, if you want to do a good job of maintenance, it is recommended to use less fast charging.
Although this is a feature that many pure electric vehicles have nowadays, which can be quickly charged, fast charging is often used, which is easy to affect the range of the battery.
Therefore, in daily life, you should charge it in time according to your own car needs, and you don't need to charge fast if you can.
It is also necessary to pay attention to the battery to avoid long-term power loss, such as when the car is not used frequently, it is necessary to replenish the power regularly.
If the battery is depleted for a long time, it will also affect the life of the pure electric vehicle, so it is recommended to check it once a month.
If you want to do a good job of maintenance, you can use regular deep discharge, which is mainly to fully charge the battery after it is completely discharged.
It is necessary to check the high-voltage components of the battery pack, such as whether the battery status and charging connection confirmation signal are normal, and whether the communication between the charging pile and the BMS can be normal.
Even if it is a pure electric car, there is coolant and brake fluid, so it is necessary to check the fluid level in all aspects every day to ensure that the coolant and brake fluid are within the normal range.
The coolant is generally replaced once every two years after driving 40,000 kilometers or about two years to better ensure the normal use of the air conditioning system and motor.
Usually check whether the interface or plug is loose, and keep these places in a normal state.
When charging, you must pay attention to the charging equipment must be qualified, do not modify the charging facilities without permission, or buy charging facilities by yourself.
Ensure that the charging temperature is not higher than 50°C and not lower than 0°C in a normal range, let alone charging in thunderstorms.
epilogue
The reason why today's pure electric vehicles are developing particularly fast is not only related to many professionals, but also related to the attention that has attracted people in this field.
For example, when people do not recognize pure electric vehicles, and few people buy pure electric vehicles, naturally not so many companies pay attention to the research of this model.
When we see the development of pure electric vehicle batteries, we can know that China's technology in this area is also constantly developing.
If you are also concerned about pure electric vehicles, but do not know how to maintain them, you must understand the above content in detail.
For people who have not yet bought pure electric vehicles, the newly developed battery is really very good news, and I believe that new energy vehicles will get better and better in the future.
