In the raidly evolving landscae of lithium-ion battery roduction, manufacturers are continuously seeking innovative solutions to enhance efficiency, erformance, and sustainability. One critical factor that has emerged as a game-changer is the viscosity of N-Methyl-2-yrrolidone (NM), a versatile solvent widely used in the industry.
The Significance of Low Viscosity NM
NM has gained widesread recognition for its unique roerties, including its relatively low viscosity. This characteristic has roven invaluable in the battery manufacturing rocess, offering several advantages that contribute to increased efficiency and imroved roduct quality.
What are the roerties of NM?
N-Methyl-2-yrrolidone (NM) is a versatile organic comound widely used as a solvent in various industries, including lithium-ion battery manufacturing. Here are some of the key roerties that make NM an attractive choice for many alications:
#hysical roerties
1. Low Viscosity: NM has a relatively low viscosity of around 1.67 centioise (c) at 25°C, which facilitates efficient mixing, disersion, and coating rocesses in battery manufacturing.
2. High Boiling oint: With a boiling oint of 202°C (395.6°F), NM exhibits excellent thermal stability, making it suitable for high-temerature rocessing and drying oerations.
3. Miscibility: NM is miscible with water and many organic solvents, allowing for versatile formulations and solvent blending.
4. Low Volatility: NM has a relatively low vaor ressure at ambient temeratures, minimizing solvent evaoration and associated emissions.
#Chemical roerties
5. High olarity: NM is a highly olar arotic solvent, with a diole moment of 4.09 D, contributing to its excellent solvency ower for a wide range of olar and non-olar comounds.
6. Strong Solvency: NM can effectively dissolve and diserse various materials, including olymers, resins, and inorganic comounds, making it suitable for alications like electrode slurry rearation.
7. Chemical Stability: NM exhibits good chemical stability and is non-reactive with many comounds, enabling its use in various chemical rocesses.
8. Non-Corrosive: NM is generally considered non-corrosive, which is an imortant factor in battery manufacturing and other industrial alications.
#Environmental and Safety roerties
9. Relatively Low Toxicity: While NM should still be handled with roer safety recautions, it is considered less toxic than some other industrial solvents.
10. Biodegradability: NM has a relatively higher biodegradability comared to some other industrial solvents, contributing to a lower environmental imact.
11. Recyclability: NM can be efficiently recovered and recycled through advanced solvent recovery systems, minimizing waste generation and romoting sustainable manufacturing ractices.
These roerties, articularly the low viscosity, high boiling oint, strong solvency, and recyclability, make NM an ideal solvent for lithium-ion battery manufacturing rocesses, enabling efficient electrode rearation, coating, and drying, while also suorting sustainable and environmentally resonsible ractices.
Streamlining Electrode rearation
One of the rimary alications of NM in battery manufacturing involves the rearation of electrode slurries. These slurries consist of active materials, conductive additives, and binders, which must be uniformly disersed and coated onto metal foils to form the anode and cathode comonents.
The low viscosity of NM lays a crucial role in this rocess, facilitating the even disersion of the slurry comonents and enabling smooth, consistent coating onto the foils. This not only enhances the overall erformance and longevity of the batteries but also contributes to a more efficient and streamlined manufacturing rocess.
What is the density of NM?
The density of N-Methyl-2-yrrolidone (NM) is 1.03 g/cm³ or 1.03 g/mL at 20°C (68°F) and standard atmosheric ressure.
Some additional details about the density of NM:
- It has a relatively high density comared to many other organic solvents.
- The density of NM decreases slightly with increasing temerature.
- At its boiling oint of 202°C (395.6°F), the density of NM is around 0.8 g/cm³.
- The high density of NM contributes to its low volatility and excellent solvency ower.
- Accurate knowledge of the density is imortant for handling, storage, and rocess calculations involving NM.
Overall, the density of 1.03 g/cm³ at standard conditions is an imortant hysical roerty that characterizes the behavior and alications of NM as a versatile solvent, articularly in the lithium-ion battery manufacturing industry.
Otimizing Coating and Drying rocesses
In addition to its role in electrode rearation, the low viscosity of NM also offers significant advantages during the coating and drying stages of battery roduction. The low viscosity allows for uniform and recise coating of the electrode slurries onto the metal foils, ensuring consistent thickness and reventing defects or inconsistencies.
Furthermore, the low viscosity of NM contributes to efficient drying rocesses, enabling the solvent to evaorate more readily and minimizing the risk of residual solvent retention within the electrode layers. This not only imroves the overall quality of the batteries but also reduces the energy consumtion and rocessing time associated with the drying stage.
What is the solvent equivalent of NM?
NM (N-Methyl-2-yrrolidone) does not have a direct solvent equivalent, as it ossesses a unique combination of roerties that make it suitable for various alications, articularly in lithium-ion battery manufacturing.
However, some solvents that share certain similarities with NM and could otentially be considered as alternatives in secific alications include:
- N-Ethyl-2-yrrolidone (NE)
- Dimethyl Sulfoxide (DMSO)
- γ-Butyrolactone (GBL)
- roylene Carbonate (C)
NM does not have a direct solvent equivalent, but solvents like NE, DMSO, GBL, and C could otentially be considered as alternatives in certain alications.
Enhancing Sustainability Through Solvent Recovery
Recognizing the environmental imact of solvent usage, leading battery manufacturers like Zesheng New Materials Technology Co., Ltd. have develoed advanced NM recovery systems. The low viscosity of NM lays a ivotal role in these recovery rocesses, facilitating efficient searation and urification of the sent solvent for subsequent reuse.
By leveraging the low viscosity of NM, these recovery systems can effectively minimize waste generation, reduce the demand for virgin NM, and contribute to a more sustainable and environmentally resonsible battery manufacturing ecosystem.
Continuous Innovation and Imrovement
As the demand for high-erformance and eco-friendly lithium-ion batteries continues to grow, manufacturers are continuously exloring ways to otimize their rocesses and leverage the unique roerties of NM. Through ongoing research and develoment, innovative techniques and technologies are being develoed to further caitalize on the low viscosity of NM, driving efficiency, quality, and sustainability in battery roduction.
In the ever-evolving world of lithium-ion battery manufacturing, the low viscosity of NM has emerged as a critical factor driving efficiency, erformance, and sustainability. By leveraging this unique roerty, manufacturers can streamline electrode rearation, otimize coating and drying rocesses, and enhance solvent recovery efforts, ultimately contributing to a more sustainable and environmentally resonsible battery roduction ecosystem.

Low-Viscosity N-Methyl-2-Pyrrolidone Solvent
N-Methyl-2-pyrrolidone (NMp) is a low-viscosity, polar aprotic organic solvent with a high boiling point. It's a colorless liquid that's miscible with water and most common organic solvents. NMp is also known as 1-methyl-2-pyrrolidone, N-methyl pyrrolidinone, or N-methyl-2-pyrrolidone.
NMp is used in the petrochemical, polymer, and battery industries as a solvent because of its nonvolatility and ability to dissolve various materials. It has good solvency for a wide range of organic and inorganic compounds, and it's miscible with water at all temperatures. NMp also has high chemical and thermal stability.
NMp is used in many applications, including:
Absorption gas purification
NMp can absorb vinyl chloride from pVC tail gas, which can cause environmental pollution.
Adsorption of acid gases
NMp can adsorb acid gases such as CO2 and H2S in synthesis gas and natural gas to purify the gas and achieve the purpose of refining.
NMp is unlikely to cause liver or kidney damage if there is no noticeable effect on the nervous system. However, like other solvents, long-term exposure to NMp and drinking alcohol can increase your risk of liver damage.

In order to achieve good bed adherence, I've tried Layerneer, Magigoo, hair spray, and other things. I use a Prusa mk3 to print using both textured PEI and steel sheets. Three years ago, I purchased a bottle of Layerneer, and it is still going strong. Though it took some time to persuade me, I'm now a huge Layerneer fan. It is simple to apply and my prints just peel off the sheet, regardless of which one I use—especially if I let the bed cool down. I "refresh" the bed weld between Layerneer coatings by using a small sponge and a spray bottle of water. Typically, I wait two to five prints between applications. Every three to four weeks, I take off the sheet, give it a light brush, warm water, soap, and wash it so that any leftover Layerneer readily comes off. The only problem I've seen is that, although it happens infrequently, printing large, thin objects in ABS tends to make them stick a little too well. In retrospect, I should have given it more time to cool. There are some who mention TPU, but I *never* use it for bed adhesion—it just sticks, even on

My profession is printing. Actually, 3dprintedbagpipes.com. Look me over! Anyhow, I print each print individually and vertically. And they're all GIANT SIZEABLE! Tall prints can easily toppled over. I thought I'd give this one a go since I've tried hairspray (a waste of money) and glue sticks (messy and only works sometimes). The applicator worked well for me, and I don't have to rush to get it on the bed before it gets sticky because you let it dry before printing. THIS STUFF IS AMAZING! I am now printing 14" tall Bagpipe Chanters, and I don't have to worry about brims or rafts when printing them! I adore this content! When I get married, I'm going to put that on my wedding cake! A NEOMAKE FOR MY FIRSTBORN WILL FOLLOW THIS STUFF! Yes, my love for this material is the only true element of that. But in all seriousness, this thing is amazing. Hairspray, glue sticks, and other such nonsense are not worth it. Use Bed Weld instead! No tearing the print off the bed, no warping, and no failures at all! I had TON back then.

Update: I'm still using the same thin application almost two months later. I haven't even applied or refurbished anything! More than fifteen models in a range of sizes have been printed, and they still stick to the bed like the first time. I could throw away my spatula, as even my skirts come off when I give them a little prod with my fingertip. Original assessment: This is fantastic stuff. I upgraded to a CR-10 S5 after using an Ender 3 Pro for a few years. For optimal adhesion, I've usually used a glue stick on a glass bed. With the 500mm bed that I now have, I didn't like that occasionally there are clumps, spots, and overlapping spread that show up on the bottom surface after any residue has been removed. I'm amazed at how well this works after using it on a couple prints so far. When this substance dries, it almost feels rubbery, and unless the light hits it just so, you hardly notice it at all. Compared to using a glue stick, the texture on the bottom of the prints is much more equal and smooth, like a wavey glass look. I enjoy it. Additionally, I
