If there is a battery that can ensure that the performance is not reduced within 15 years; it has at least 20,000 times of "0 to 100% full charge and discharge" life; if it is used in the car, it can ensure that at least 2 million kilometers of performance is not attenuated; a charge can maintain a cruising range of at least more than 1,200 kilometers; at the same time, its price is half cheaper than lithium batteries, minus 40 degrees Celsius can be used normally, and a pure tram only takes ten minutes to fill...
So what do you say, the first thing that comes to mind? That's right! That is: if this battery is applied to the car, then pure electric vehicles will usher in the real spring! ——Recently, the battery industry has ushered in good news! A battery called "Ea2I" was officially announced, and it is said to be commercially available in 2022 (that is, this year)!
"Ea2I battery" or commercial in 2022
The stock price of CATL was thus affected
This new battery is an "enhanced modified aluminum-ion graphene battery" (unlike traditional lithium batteries), it is all solid state, does not contain any liquid, so it is extremely safe. Using the abundant aluminum resources on the earth, there is no need to consume nickel, cobalt and other metals required by the lithium battery industry. Has an independent graphene electrode with.
According to the official data, the quality energy density of this battery is 350-550 Wh / kg (the current lithium battery used by Tesla is only 300Wh / kg); and the volume energy density is 1200-1500 Wh / L, which is indeed much higher than the best lithium battery in the world.
As soon as the news came out, the domestic lithium battery "boss" Ningde era suffered a heavy blow, and the stock price plummeted by more than 8% overnight, because this battery is the world's first commercial-grade aluminum-ion solid-state battery. However, when the practitioners of the domestic battery industry further excavated this news, they had a lot of doubts, even doubts.
Inventor Saturnose Company is an Indian enterprise
Official promotional materials look hardcore
The first company to propose this battery is called Saturnose, registered in delaware, USA, but it is an Indian company (this is similar to "Didi International" registered in the British Cayman Islands, similarly), the magic is that this company was just established in April this year...
Although they claim that the battery was developed for 5 years, although they claim that "it is supported by two rounds of seed funding from Saudi Arabia's Dana Venture Fund", although they claim that "this battery is supported by the Indian government", although they claim more and more other things that sound like trouble...
However, for now, it is impossible to find the company's patent information on "aluminum-ion batteries"! Add to that the "Indian background" of this business... Always seems to give people a feeling of unreliability? It is very doubtful whether the battery, called "Ea2I", has been soaked in the water of the Ganges.
But many of the backgrounds are questionable
It's hard to tell if it's true or false! Cause widespread mistrust
Today, the electric vehicle industry continues to heat up, and the entire industry is left with only one last link - the battery still seriously lacks "substantive breakthroughs". Therefore, any battery company as long as the official announcement "made a major breakthrough in the new principle of energy storage" may be able to attract huge investment (of course, where will the invested money be used after this is another statement).
At present, the international cooperation units involved in graphene aluminum-ion battery projects are: Stanford University, Cornell University, Clemson University, University of Maryland, University of Nebraska, Polymer Department of Zhejiang University, Dalian University of Technology, and The European Arion Industrial Alliance. At present, the research and development of graphene aluminum ion batteries is at the forefront of the University of Queensland in Australia. However, in this "Graphene Aluminum Ion Battery Global Alliance", we did not find any relationship with India (but there are indeed Indian researchers in it).
True or false we can not distinguish between the real and false, anyway, they said, in 2022 commercial listing. That being the case, you might as well wait! Anyway, it's 2022! In another month, our Chinese Lunar New Year has passed! So if you can't get on it in 2022, it's them bragging. In fact, in the previous few years, the news about "new principle batteries" was one after another.
The "new principle" of super energy storage has risen and fallen
But in the end, you need to speak in real objects!
For example, the "Stanford University battery made of table salt" just announced 2 months ago has 6 times the power storage and 6 times the battery life (the "energy density" of this battery reaches 1200mAh/g, while the energy density of conventional car lithium batteries is only 200mAh/g)...... For example, we are more looking forward to the "rubidium titanate high-voltage capacitor" super energy storage technology that GAC Group is engaged in.
"Rubidium titanate high-voltage capacitor" energy storage density can be at least 5 times more than lithium batteries (5 to 10 times); charge and discharge cycle life of at least 100,000 times (10 to 500,000 times), at least 10 years of performance does not decay; fast charging speed, due to no conversion loss of electrical energy / chemical energy, the utilization rate of electric energy is as high as 95%; ultra-low temperature characteristics are good, the temperature range is wide -50 °C ~ +170 °C; high safety factor, there is no flammable and explosive substances; green environmental protection, no pollution...
But whether these cases will eventually come up with the "future energy storage" that the people can really use is unknown. For example, GAC's "Rubidium titanate high-voltage capacitors" are claimed to be commercialized during the "14th Five-Year Plan" period, especially in 2023 or 2024. As for whether they can do it, or this sentence – sit and wait! Take something out to count!
After all, in the early years, the "graphene lithium sulfur battery" developed by the University of Colvardo in Spain was optimistic about Airbus, Volkswagen, and BMW, and it obtained several investments, established GRABAT Company, and was also favored and invested by the famous Chint Electric in the mainland. In 2016, they even took out physical samples but 5 years have passed, and now the GRABAT project is not clear whether it is dead or alive, and the official website has not changed a word in the past 6 years...
We'll be lowly in the next issue
