Are lithium-ion batteries solvent-free?

In response to the growing demand for lithium-ion batteries (LIBs), we demonstrate a solvent-free manufacturing technology that can avoid toxic organic solvents and form unique electrode structures to overcome the bottlenecks in low costs and fast charging.

Is slurry casting a viable alternative to solvent-free lithium-ion batteries?

The rise of the production of lithium-ion batteries (LIBs) calls for a global improvement of the electrode manufacturing process. At present, slurry casting is the standard technique. The solvent-free (SF) approach appears as a prominent alternative as it avoids the use of toxic solvents and decreases the 2023 The Authors.

Is a scalable dry electrode process necessary for lithium based batteries?

Scalable dry electrode process is essential for the sustainable manufacturing of the lithium based batteries. Here, the authors propose a dry press-coating technique to fabricate a robust and flexible high loading electrode for lithium pouch cells.

What are lithium ion batteries?

Lithium-ion batteries (LIBs) [4, 5] are one of the most promising energy technologies. They are rapidly gaining popularity in new energy vehicles, intelligent gadgets, and electronic devices due to their high energy density, excellent efficiency, and long cycle life [6, 7, 8].

How are lithium ion batteries made?

Lithium ion batteries have also been manufactured using spray painting techniques by using NMP based paints to spray each electrode component onto the desired surface 20. While this allows for battery fabrication on a variety of surfaces it still requires the solvent to be evoporated.

How to reduce the manufacturing cost of lithium ion batteries?

The cost of batteries mainly consists of two parts, i.e., raw materials and manufacturing costs. Reducing manufacturing energy consumption and increasing electrode thickness are two effective methods to lower the manufacturing cost of LIBs .
