How does the manufacturing process affect the performance of lithium-ion batteries?

The manufacturing process strongly affects the electrochemical properties and performance of lithium-ion batteries. In particular, the flow of electrode slurry during the coating process is key to the final electrode properties and hence the characteristics of lithium-ion cells, however it is given little consideration.

Can aqueous based cathode slurry be used for battery production?

Although the aqueous-based cathode slurry is easy to be transferred to the current coating technology without extra cost, the sacrifice of capacity and cycle stability is not acceptable for battery production. Solvent-free manufacturing emerges as an effective method to skip the drying process and avoid the organic solvent.

Can planetary mixer slurries be used for lithium-ion batteries?

When producing electrode slurries for lithium-ion batteries, it is be necessary to break up potential agglomerates and avoid local material accumulation on a microscopic level. Currently, planetary mixers are preferred for mixing battery slurries for cathode and anode. But is this really the best and most efficient method for mixing battery masses?

How will lithium-ion batteries be produced in 2030?

According to current studies, the demand for cars, portable devices, and energy storage is expected to increase by more than ten times by 2030. To meet the rising demand, ever larger and more efficient battery factories are required. The mixing process is the first step in the production of lithium-ion batteries.

What is the mixing process of lithium ion batteries?

The mixing process is the first step in the production of lithium-ion batteries. It is crucial for the quality of the battery and has one of the greatest impacts on the cell's performance. In the mixing process, active material, binder, and conductive additives are mixed with a dispersion agent like water or solvent to form a slurry.

What is ball milling & slurry mixing in battery manufacturing?

Ball milling is also a common method for dry powder and slurry mixing in battery manufacturing. For the dry powder mixing, the surface energy and work of adhesion of ingredient particles plays an important role in the particle distribution.
