On March 30, Aion held the magazine battery 2.0 shooting test conference. It was the first time in the world that the whole battery pack could not be fired, and it solved the battery safety problems in extreme environments such as instantaneous short circuit and explosive damage of multiple batteries for the first time. If the magazine battery passed the acupuncture test before, it was "bravely climbing Mount Everest", then the difficulty of passing the gunshot test for the magazine battery 2.0 released this time is comparable to "manned landing on the moon", which once again defines a new standard for battery safety.
From acupuncture to shooting, from the era of cold weapons to the era of hot weapons
Aion's magazine battery 2.0 shooting test is the most stringent battery safety test so far, shooting at a full pack of fully charged batteries with reserved shooting openings at a distance of 15 meters. Compared with the well-known acupuncture test, the gunshot test simulates a more extreme and harsh scene. When the bullet penetrates the cell, its speed can reach 975,000 times that of acupuncture, and the diameter of the wound is 7-8 times that of acupuncture. It can instantly penetrate multiple cells and cause thermal runaway and explosive damage. In the face of such severe challenges, the industry's mainstream lithium iron phosphate single cells and the industry's mainstream lithium iron phosphate modules have experienced obvious thermal runaway and combustion phenomena, which means that the intrinsic characteristics of the cells alone cannot Realize real security. However, the magazine battery 2.0 did not catch fire or explode after being shot. After disassembling the battery system case, the overall structure was complete, and only three cells were burst damaged. After standing for 24 hours, the temperature returned to normal temperature and passed the shooting test. . This is also the first time in the world that the power battery has achieved no fire and no explosion in the gun test.
The current national standard power battery safety test standards include acupuncture, drop, burning, impact, etc. Acupuncture is the highest safety standard for battery car regulations. It requires the battery not to catch fire within 5 minutes after being punctured by an 8mm steel needle. Previously, the industry had only Less than 3% of the brand's batteries can pass, and the magazine battery released in 2021 is the first battery technology that can achieve the non-ignition of the whole pack of ternary lithium. The magazine 2.0 released by Aian this time has upgraded the battery safety test standard from acupuncture to gunfire. This leap is comparable to the era of cold weapons and fast-forwarding to the era of hot weapons.
Judging from the spontaneous combustion data released by the National Emergency Management Department in the past two years, battery safety is still a pain point and problem in the industry. Wang Qingquan, Director of R&D of Aion Battery, said at the press conference that even if the risk is one in ten million, it takes ten million times of effort! The reason why Aian will continue to study battery safety technology and make technological breakthroughs time and time again is derived from the belief in Aian's bones - the ultimate pursuit of safety.
Three original breakthrough technologies to create the ultimate security protection
In order to provide users with the ultimate battery safety protection, on the basis of the original magazine battery, Magazine Battery 2.0 has made breakthroughs in research and development of a series of original safety technologies such as ultra-stable electrode interface, heat-resistant phase-change material, and battery fire extinguishing system. The ultimate battery safety protection.
For lithium-ion batteries, the electrode interface is the most active area in the cell. In order to enhance the stability of the electrode interface, Magazine Battery 2.0 has developed the "ultra-stable electrode interface" technology. The nano-ceramic material with ultra-high stability and ultra-high heat resistance greatly increases the toughness of the electrode interface; the application of composite current collector materials can quickly collapse when heat accumulates to avoid continuous short circuit; at the same time, Aion is still elastic Oxidation-resistant flame retardants are added to the electrolyte of the cartridge battery 2.0. After activation at high temperature, it can capture the free radicals of the combustion reaction and cut off the conditions for continuous combustion. Under the protection of triple technology, even if thermal runaway occurs in the battery core, its heating rate can be reduced by 20%.
In addition to improving the intrinsic safety of batteries, Aion has also cooperated with China Aerospace Science and Technology to develop a heat-resistant phase-change material with dual functions of heat insulation and phase-change heat absorption. The phase change latent heat of this phase change material is 10 times higher than that of conventional materials, and it can absorb a large amount of heat while maintaining the same temperature. With the mesh nano heat insulation material, the overall heat insulation performance is greatly improved by 40%. On the other hand, the magazine battery 2.0 adopts a double-layer cooling system to cool the top and bottom of the battery core at the same time, the overall cooling efficiency can be increased by 80%, and the temperature of the upper case is also reduced by 75%, which further ensures the battery pack. Safety of occupants above.
For extreme scenarios where the entire battery pack may be damaged due to external reasons, Aion's engineers have also equipped the magazine battery 2.0 with a battery fire extinguishing system. It uses a low-melting point alloy to form a fire extinguishing chamber, and realizes storage of fire extinguishing agent, self-positioning of thermal runaway cells and fixed-point spraying in a very small height space. When the thermal runaway of the battery cell occurs, a large amount of fire extinguishing agent is sprayed on the battery cell instantly and accurately. The fire extinguishing agent can capture the free radicals of the combustion chain reaction while absorbing heat and vaporizing, forming an inert gas atmosphere. Combined with Aion's thermal runaway gas emission treatment technology, it can eliminate sparks and 99.5% of PM10 in the exhaust. The application of this technology makes the magazine battery 2.0 the only battery technology with its own safety "fire brigade".
In addition to the above-mentioned passive battery safety technology, Aian has also developed a sixth-generation cloud-based battery management system based on big data and AI technology. Thanks to more than 600,000 vehicles and 1300TB of full-life cycle application data, the sixth-generation cloud battery management system has greatly improved the ability to identify faults such as self-discharge abnormalities, cooling abnormalities, electrical connection abnormalities, and hidden insulation faults. The recognition ability of AI has reached 200Ω level, which is much higher than the risk line of 10Ω, which can realize early diagnosis and prevent unburned.
The application of the above technologies has increased the comprehensive thermal runaway management capability of the magazine battery 2.0 by 5 times, and can resist the impact of thermal runaway of multiple batteries at the same time.
The technological blowout has ushered in, and the unicorns on the Science and Technology Innovation Board have unlimited potential
Compared with new energy car companies, Aion is more of a technology company. From the first generation of magazine batteries to magazine batteries 2.0, Aion has achieved breakthroughs in the field of battery safety again and again, not only because Aion can be closer to the needs of consumers from the perspective of vehicle safety, but more importantly, they are in electric technology. In terms of long-term resource investment and technology accumulation.
In 2022, "Forbes" released the list of global unicorns, and Aian topped the list in all dimensions. Behind the super unicorn, Aion started the research and application of electrification technology as early as 2011. Today, it has established a world-leading battery research and development team, and has a leading battery laboratory, professional testing field and The battery production workshop is one of the very few car companies in China that has independent design and manufacturing capabilities for advanced batteries. Last year, Aian even invested 10.9 billion to establish Yinpai Battery Technology Co., Ltd., focusing on the development and application of forward-looking battery technology, laying a solid foundation for opening up the battery R&D, design, intelligent manufacturing, sales and service chain.
Previously, it was reported that the cooperation mode of the development project of AH8, the new model of Egypt Safety, has been adjusted from joint development with Huawei to independent development. As a science and technology unicorn, Aian does not lack the confidence and strength to change the cooperation model with Huawei. Since its establishment, Aion has always focused on EV and ICV full-stack self-research, and Aion has accumulated rich scientific and technological achievements. In addition to releasing core three-electric technologies such as magazine battery series, super-speed batteries, sponge silicon negative electrode batteries, microcrystalline iron-lithium batteries, and quark electric drives in the EV field, Aian has also invested in the ICV field to build the ADiGO smart driving interconnection ecosystem. , has realized the accelerated iterative upgrade of over-the-horizon call parking, high-speed NDA, urban NDA and smart cockpit technology. In November last year, it released a new generation of protoss electronic and electrical architecture, which can bring users All-weather safe smart driving experience. The release of Magazine Battery 2.0 not only redefines the standard of battery safety, but also proves that Aian is a unicorn in science and technology.
As Zhang Xiong, deputy general manager of Aian, said at the press conference, "Promoting social progress is Aian's relentless pursuit." Magazine battery 2.0, as a complete battery pack technology, can match battery technologies such as long battery life and ultra-fast charging. It will not only be gradually equipped with Haobo for mass production applications, but will also empower deep diving, aviation, and aerospace with the ultimate battery safety performance. and other fields continue to evolve and accelerate the realization of energy transformation.
Today's Aian has a complete industrial chain layout and strong R&D capabilities, and the technology blowout period has arrived. When Aian sprints to the Science and Technology Innovation Board as a technology giant, the imagination left to the capital market is huge.
