Next, we start from? Maxwell? Explain the unique stunt "dry electrode" technology in detail, and see how it helps Tesla achieve a new leap in energy efficiency and cost, and what impact the addition of dry electrode technology has on consumers.
20 19? Tesla acquired in 2008? Maxwell? An exposed document shows that Maxwell? Dry electrode technology is the pillar technology of supercapacitor, which will be used in lithium batteries in the future and become the new favorite of electric vehicle market.
When Tesla invested? 2.35? A billion-dollar acquisition? Maxwell? When the news came out, people didn't know? Musk? What do you want to say to supercapacitors (Maxwell? ) or other battery technologies.
Soon, Musk? It reveals the original intention of "Xiang Zhuang's sword dance is intended to serve the public".
So Tesla bought it? Maxwell? Don't use supercapacitors on electric cars, Musk? What really matters is. Maxwell? Other technologies are in hand-and these technologies will greatly affect Tesla's future business.
"This is a great event. Maxwell? There are many technologies in hand, and if they can be applied correctly, they will definitely have a great impact. "Musk? Said.
Maxwell? It is a well-known leader in the design and manufacture of high energy density supercapacitors in the industry. It provides continuous support for the company's business, including the integration of renewable energy, the electrification of traditional vehicles and the acceleration of the growth of the electric vehicle market. It's a perfect match with Tesla.
Take? Models? 3? For example, what is the energy density of this super best-selling electric car now? 2 10? WH/ kg (battery capacity), what is the battery capacity? 275? WH/L .
Maxwell? It is claimed that you can achieve energy density with your own technology? 300? WH/ kg, up to? 42.8%。
But, 300 WH/ kg? That's not all. How much does Maxwell plan to further increase this number? 500? WH/ kg
Such a huge improvement is definitely a blockbuster for the electric vehicle market.
Can Tesla follow the trend and keep his car alive? 220? Miles (about? 354? Km) to? 375? Miles (about? 603? Kilometers).
In addition to surface improvement such as battery life, Maxwell? Dry electrode technology can also greatly simplify the manufacturing process. Can the manufacturing cost be reduced when the battery life is doubled? 10-20? Percentage points.
Maxwell? This means that a special powder can be made into a dry film electrode.
Judging from the prototype product demonstration, Maxwell? It can improve the discharge rate while maintaining the same capacity, which is much stronger than similar products on the market.
So, what is the strength of dry electrode technology?
At present, all lithium batteries on the market use wet electrodes, and this technology needs to use toxic solvents containing binder materials in the production process.
After the coating is completed with the help of complex conformal coating, it needs to be dried, and the drying line is very long and consumes a lot of energy.
After using the dry electrode, the drying step can be directly skipped, which saves money and time.
Crucially, dry electrode technology is not? Maxwell? This concept assumes that it has been used commercially for many years (making supercapacitors).
In addition, dry electrode technology can also reduce battery performance degradation.
Nowadays, dry electrode technology can be operated on a large scale and can be seamlessly combined with existing lithium battery technology.
Judging from the available information, Maxwell? Dry electrode technology can at least improve the energy density of batteries? 20-30? Percentage points.
So, what benefits can consumers enjoy?
First of all, of course, the energy density is improved and the cost is reduced.
This year? 5? In May this year, it was reported that Tesla was applying for a new patent for this battery, which described the nickel, cobalt and aluminum used in the manufacturing process of lithium batteries. (NCA)？ Method and technology of electrode synthesis.
This patent can not only improve the battery life, but also reduce the battery production cost.
What does it matter? Musk? Has been formulated to "extend the service life of electric vehicle batteries? 160? The goal of "10,000 kilometers" coincides with mine. Moreover, Tesla's breakthrough process in the field of batteries has been confirmed by insiders.
It is reported that Tesla is about to make a technological breakthrough in batteries, which is mentioned in the information between Tesla employees and customers. It is reported that these include battery production cost, energy density, battery life and cobalt-free battery design.
Whether the cruising range is improved or the price is reduced, the profits are earned by consumers.
Of course, Tesla may also look at the dishes on the plate, such as in? Models? S/X？ The endurance of such flagship models is constantly improving, but in? Models? 3/Y？ In fact, sales can be increased by lowering the price.
Although this is only a guess, the endurance of all Tesla models will definitely improve in the future.
Second, in? Maxwell? With the help of technology, consumers will definitely experience faster charging speed, which has always been one of the pain points of electric vehicles.
For Tesla, the benefits are more.
First of all, Musk? It is possible to apply supercapacitor technology to its own energy storage equipment and get closer to its vision of transforming into sustainable energy.
Secondly, the elimination of toxic solvents and the improvement of energy density and service life of new batteries are also great contributions to environmental protection.
Maxwell? Point out that the battery with new technology is being completed? 500? Can it be maintained after the second charge-discharge cycle? 90%? The ability. If most users charge the battery at the rate of one week, the battery capacity will drop to? 9? Shicheng, has this car been used? 30? A few years.
How will the strong addition of dry electrode technology affect the relationship between Tesla and Panasonic?
This question is not difficult to guess. After all, these two once close comrades-in-arms have been somewhat alienated.
Except for the acquisition? Maxwell, Tesla has also established contact with many suppliers of power batteries in China. There is even news that Tesla will cooperate with Contemporary Ampere Technology Co., Ltd. to manufacture millions of miles of batteries.
Of course, Panasonic will not wait for death. Last year, Panasonic reached a cooperation with Toyota to sell lithium batteries to other automakers such as Honda.
Of course, Tesla and Panasonic will not be completely stiff in a short time, and the latter will continue to help Tesla produce batteries in the Nevada super factory.
Undoubtedly, acquisition? Maxwell? Will greatly enhance Tesla's hard power.
Given? Musk? There are already many technical reserves in hand, and it is believed that the commercialization speed of dry electrode technology will be faster than expected.
Besides dry electrode technology, battery day? Musk? It may also reveal the news of cobalt-free batteries.
It is conceivable that Tesla will further expand its leading edge in the future and even completely sentence the death penalty of traditional diesel locomotives.
Finally, the model equipped with the latest battery technology may also appear on battery day, or it may not be replaced for a long time? Models? s？ Or? Models? Ten.
