As the domestic auto market has gradually entered the new energy era, the competition between the automobile industry has shifted from the "oil battle" to the "battery war", and it has become the industry consensus that the battery winner wins the world. So in the "battery arena" of competition, who is the best form of power batteries for new energy vehicles in the future? I think the birth of Geely's "Aegis short knife battery" undoubtedly pulls the volume of the automotive industry to another height.
Why does the battery have to be "short"?
As we all know, the importance of battery, motor and electronic control technology for new energy vehicles is comparable to the "three major parts" of fuel vehicles. Among them, the power battery, as the core of pure electric vehicles, is even more important. What are the advantages of Geely's latest "Aegis short knife battery"?
In fact, judging from the name, this battery gives people a sense of "vast and sharp", and the name "short knife" feels like a peerless weapon that only a martial arts master will have, which can not only seal the gods with a knife, but also carry out its own solid defense at close range.
In fact, this battery is indeed very distinctive: first, its shape is very "short", "short" to the battery length of only 580mm, which has the advantage of not only being more flexible in the layout of the whole vehicle, but also more widely adaptable. Since it's called a "short knife", there must be a "long knife" on the market, that's right! Compared with the long knife battery, the internal resistance of the Aegis short knife battery will also be smaller, so that the heat of the battery cell is less, which can effectively reduce the safety risk itself.
The second is that it has a high energy density, and Geely has increased the level of energy density of its batteries to 200Wh/kg. You must know that the leader in this field, the energy density of the second-generation blade battery of a certain Di is only 190Wh/kg, and the energy density of the Aegis short knife battery is 10Wh/kg higher than the former, which means that it can provide longer battery life performance at that time, and the range anxiety that consumers are worried about will be further disintegrated.
Third, its cycle life is longer, because it uses multi-element doped cathode materials, as well as small particle anode materials, combined with its small size, small internal resistance and other advantages, the internal chemical reaction speed is effectively slowed down, according to calculations, the cycle life of Aegis short knife battery can reach 3500 circles, equivalent to a safe driving mileage of up to 1 million kilometers, equivalent to 25 times around the earth.
Finally, it also has a faster charging speed, because the Aegis short knife cell physically solves the problem of high internal resistance of the long knife, and at the same time uses carbon nanotubes with a finer diameter and longer length, and adds additives with lower film-forming impedance to the electrolyte, so as to quickly and greatly improve the fast charging performance. Under the same battery capacity, the 10~80% SOC charging time of the long knife battery takes 26 minutes, while the Aegis short knife battery only takes 17 minutes and 4 seconds.
Can the "short knife" really reach the military level?
It is undeniable that the development of pure electric vehicles in the past two years has made a great breakthrough, but if you look at the penetration rate, there are always more than sixty percent of people who prefer to choose oil vehicles, and the main reason for this, in addition to the anxiety of the range of new energy vehicles, from a technical level, the safety of power batteries is the most headache.
But this time, the Aegis short knife battery brought by Geely is really "not simple", and it is not an exaggeration to say that it has reached the level of military-level security. Why can it be so sure of its safety level, because this battery has already passed various devil tests, and it can be called "up the knife mountain, down the sea of fire" is not afraid.
Specifically, in the six "devil" serial tests carried out by the China Automotive Center, the Aegis short knife battery has undergone 6 tests, including seawater surfing, plateau extreme cold, high-frequency bottom scraping (3 times scraping), extreme crushing, battery pack side pillar collision, and flame scorching. These tests are undoubtedly very difficult, and they also have a number of industry-first high-difficulty test conditions, which can comprehensively evaluate the performance of the battery pack under various extreme conditions, and the Aegis short knife battery can not only pass easily, but also has no fire, explosion, smoke and other thermal runaway phenomena during the test process, with a high degree of safety and reliability.
What's more worth mentioning is that in the "8-needle puncture" test of China Automotive Research Institute, the battery cell of the Aegis short knife battery was punctured by 8 steel needles with a diameter of 5mm at the same time and stood for 1 hour, but still did not smoke, fire or explode. Everyone is very impressed by the appearance of the Tesla pickup, but what is the effect of the battery? This short knife battery has passed the world's first 5.8mm real bullet penetration test cell, and even under such extreme damage conditions, it can still not catch fire and not explode. Bullets are not afraid, and at the same time, seawater immersion, falling and heavy blows, and external fires are all passed safely, which undoubtedly proves the safety of the battery again, and this "Aegis standard" will also improve the safety standards of the industry again.
The Galaxy E5 became the first model
Of course, whether the battery is good or not, you have to really use it in the real car to know, and the Galaxy E5, which will be launched in the second half of the year, has become the first rider of the "Aegis short knife battery".
As a global model developed simultaneously for domestic and foreign markets, the Galaxy E5 is not only fashionable and avant-garde in appearance and interior, but also full of "black technology" all over its body. This car is built on the GEEA 3.0 electronic and electrical architecture, and adopts advanced technologies such as CTB battery-body integration technology, Galaxy 11-in-1 intelligent electric drive and Flyme Auto in-vehicle system. At the same time, with the blessing of the G-TCS all-weather drive anti-skid system, its official elk test speed is as high as 78km/h, and the 0-100km/h acceleration time is 6.9s, which is undoubtedly quite good.
As for the battery, the Galaxy E5 provides Geely's self-developed Aegis short knife battery of 49.52kWh and 60.22kWh according to different configurations, corresponding to CLTC pure electric range of 440 km and 530 km. With the addition of the Aegis short knife battery with higher safety, longer life and longer battery life, the Galaxy E5 will successfully end everyone's prejudice against new energy vehicles, and safety, efficiency and long life will become synonymous with Geely's new energy vehicles.
Write at the end
"As soon as the short knife comes out, who will compete"! The birth of Geely Aegis short knife battery, undoubtedly to the entire battery industry has brought a great impact, after all, it can reach the industry-leading level in terms of safety performance, energy density, charging performance, low temperature resistance and cycle life, Geely seriously "roll up" words are really scary. Nowadays, Aegis short knife battery has become a new star in the battery industry that cannot be ignored, and we also believe that it will lead Geely new energy vehicles to a higher place and bring more surprises and power to the industry!
