Do you know that the new battery technology under the NMP supply chain can meet the two needs at the same time? !

Follow me on:

The focus of the new energy field to which NMP belongs is technology development. Which company’s technology update is safer, which company has the right to speak in the industry! Today, the editor will introduce to you the development and trends of two leading battery technology innovation companies. WIT FENGZE & ZESHENG not only focus on NMP production and supply for more than 10 years, but also always pay attention to the new information of upstream and downstream supply chain, and organize and share with you every week. These two companies with new research results on batteries will play an unpredictable role in the development of the new energy industry. Please follow the editor to understand what kind of new battery technology:

What’s so great about the new battery technology this time? It can meet the needs of electrification and sustainable development at the same time! No matter how vast the universe is, there is only one Earth that we know so far that is habitable for human beings. Therefore, no matter what technology is developed and developed, it is one of the primary tasks to promote energy recycling, promote sustainable development, and protect the environment. The NMP (N-methylpyrrolidone) waste gas recovery system of Smart Fortress & Zesheng New Materials also follows the same purpose and essence, making a significant contribution to protecting the environment and promoting energy recycling. Closer to home, let’s take a look at which two battery companies are.

[Theion of Germany developed a crystal battery]

Headquartered in Berlin, Germany, Theion is a team of leading scientists, engineers and entrepreneurs. For example, Marek Slavik, one of the world’s leading chemical scientists and battery experts, is the co-founder and CTO of Theion. Theion, which started with lithium-sulfur crystal cathode technology, has also developed a new technology that can triple the cruising range of lithium-ion batteries, but uses only one-eighth of the energy.

Crystals of lithium sulfur

Sulfur (Li2S) is a very promising cathode material (like NMP solvent, which is also used as cathode material for lithium batteries), the cost is only 0.20 EUR/kg, compared to the cost of other cathode materials such as NMC811 Only 20 EUR/kg and has 3 to 5 times the theoretical energy density. By using sulfur as the cathode material, it is possible to bring energy density to a whole new level while reducing costs.

Ulrich Ehmes, Theion’s new CEO, said,”The really dramatic change occurs when lithium sulfur is transformed into a different structure.We put a cover of carbon nanotubes [percolation network] on top of it, orient the carbon nanotubes, and then crystallize around the carbon nanotubes the whole sulfur, obtaining a solid structure of carbon nanotubes with a crystalline structure of sulfur around it. Some other process steps are added in order to make the cathode ready to be integrated into the battery cell, which is a perfect cathode.”

Theion’s crystalline cells are not only technologically novel, they also offer many advantages: high capacity (up to three times the weight and volumetric energy density), cycle life similar to state-of-the-art technology, fast charging capability, high safety (non-flammable components) and low cost (sulfur cost is 1% of NMC811 cost). In addition, sulfur is an industrial by-product (doesn’t need to be mined, ecologically damaging), and it is safe and cheap to recycle. This is yet another similarity to NMP solvents, which are highly recyclable.

“The target application for our cell chemistry will be all mobile devices and vehicles, where weight and volume matters,” said Ehmes. “However, the very first market we will address is space, a niche market where lightweight batteries are required.”Ehmes is very clear about Theion’s future plans:

  • The first samples of electric pumps powered by crystal cells that will be used in commercial rockets will be launched by the end of this year (2022);
  • In 2023, Theion plans to deliver the first samples to eVTOL airliners (air taxis) and all mobile devices including cell phones, laptops and wearables;
  • In 2024, the focus will shift to electric long-range airliners and electric vehicles!

【OneD Battery Sciences has developed Sinanode technology based on the use of special silicon nanowires】

The second battery company I’m introducing today is Palo Alto, California-based OneD Battery Sciences, a global innovation leader that developed the Sinanode technology. This technology uses special silicon nanowires to significantly improve graphite anodes and can effectively improve energy density, electric vehicle battery life and cost efficiency. It is also a new technology that plays an important role in promoting the development of the industry.

The Sinanode pilot plant in Moses Lake

Beginning in May, OneD’s first pilot plants will open to OEMs in Moses Lake, Washington. Each pilot plant uses one CVD machine and can produce about 100 tons of material per year. The purpose of the pilot plant is this: In order for OneD customers to qualify their batteries, they must first have sufficient quantities to manufacture so-called optimized batteries. And OneD has developed a prototype battery with SINANODE anode and commercial cathode in the 4690 EV battery format (46mm diameter, 90mm length). There are about 1,000 of these cells in a typical EV battery pack. After optimizing EV battery prototypes, the pre-production qualification process often requires quality testing before commercial vehicle production. The qualification process typically requires up to 10,000 battery packs. If the energy storage of each battery pack is 100 kWh, the qualification process requires 100 MWh of anode material.

OneD says they can easily produce the volume the market demands with a new CVD machine installed at Moses Lake. Complete production plan: The maximum annual output of a single machine is about 340 MWh. According to OneD, this is the most efficient way to produce silicon-carbon anode materials from a capital and variable cost perspective.

“We’re currently doing all the production out of our Palo Alto production facility,” according to Vincent Pluvinage, CEO at OneD. “However, that’s not the ideal place to do that because it’s not an industrial setting and we are very constrained. That’s why we decided to build our first pilot plant in Moses Lake.”

Yes, in order to become bigger and stronger in the field of new energy, environmental problems must be solved. If you don’t solve environmental problems, “the environment will solve you”! WIT FENGZE & ZESHENG also grasped the point of environmental protection, researched, developed and manufactured an NMP exhaust gas recovery system, which solved the NMP (N-methylpyrrolidone) exhaust gas emission and recycling problems for battery companies.

wind energy

As far as is known, there are two main uses of NMP-based Li-ion batteries. One is a mobile lithium-ion battery for powering new energy vehicles, electric yachts, etc.; the other is a lithium-ion battery for renewable energy such as wind energy and solar energy. OneD believes that these markets for lithium-ion batteries need to be balanced, so their plan is to provide each electric vehicle customer with their graphite processing and silicon nanowire addition pilot facilities, without affecting the supply chain of electric vehicle customers. Under the premise, different new anode materials will be optimized; in the future, the breakthrough Sinanode technology will continue to be improved to meet higher market demands.

WIT FENGZE & ZESHENG will also take these two companies as the second development goal, learn their foresight and development strategy, and produce and supply more NMP solvents that are more in line with market demand for the development purpose, and continue to be in the new energy industry. Write a glorious chapter that belongs to us.
