How to improve the safety of lithium batteries with NMP as one of the raw materials? !

Today is June 7th. The editor wanted to search for more professional knowledge about NMP (N-methylpyrrolidone/N-methyl -2-Pyrrolidone ), but found news on the Internet about the fire of these energy storage systems such as lithium batteries. A 2021 report by the U.S. Environmental Protection Agency can find public records of such fires in 28 states from 2013 to 2020; one place with more than a dozen fires in a year was also flagged.

With the expansion of the global NMP (N-methylpyrrolidone) market and the surge in the market for lithium batteries and new energy vehicles, not only the finished products of these energy storage systems may catch fire, but the recycled products that can be recycled for too long also have fire risks. How to improve the safety of energy storage systems such as lithium batteries has become a top priority in the new energy industry. (Of course, NMP solvent is used in lithium batteries to make the performance of lithium batteries more stable and safer. For more details, please click to read the previous related articles.)

A topic that the new energy industry we need to think about at this stage is how to reduce the cost of battery’s production, improve the performance of batteries, and ensure the safety of finished battery products and the safety of recycled products without damaging the ecological environment. Everyone in the industry knows that making new batteries needs to mine thousands tons of lithium and cobalt from salt flats and deposits around the world; This process  not only destroys the environment, but also makes the cost of raw materials of batteries more expensive .

So Fengqi You the professor of engineering from Cornell University, began studying the life cycle of elements such as lithium in energy systems, saying we should recycle everything we can. In other words, in fact, the resources in this world are limited, which cannot be robbed, and more attention should be paid to the link of recycling. Only by recycling resources can let human beings is possible to live forever, and the earth can keep its rotation. Therefore, not only the battery recycling facility was born, but even the NMP (N-methylpyrrolidone) solvent used in battery production was developed by the WIT FENGZE&ZESHENG team to develop an NMP waste gas recycling system. The new energy industry itself is a green new generation industry. Only by working hard towards green technology can let we continue to grow and develop.

Fengqi You, the professor of engineering from Cornell University, also noted that key metals, such as lithium, contained in old batteries, such as the one that started a fire in Scottsdale in 2019, are ripe for extraction and pumping back into the supply chain. . With these complete recycling facilities, the new energy industry can reduce the mining of metals such as lithium and cobalt; when used batteries are recycled, there will be no hoarding of used batteries, thereby reducing the risk of fire in the garbage bin.

Just like the NMP (N-methylpyrrolidone) solvent is produced and supplied by WIT FENGZE & ZESHENG, it will contain a lot of impurities after use, and it will also pollute the environment and affect human health if it is directly discharged into the air; but if the NMP waste gas recovery system is used , all the problems will be solved. It not only protects the ecological environment, but also protects the health of employees, but also saves the cost of producing NMP solvent, killing three birds with one stone.

WIT FENGZE & ZESHENG not only produces and supplies NMP solvent, which can make the performance of lithium battery more stable; it can also customize a set of NMP waste gas recovery system for the cooperative battery factory to protect the environment and the health of employees; it can also improve the performance of lithium battery. Security helps a lot.
